FDA Recognized Consensus Standards for Medical Devices: Complete Guide (2026)

Why FDA Recognized Consensus Standards Matter

Every medical device submitted to the FDA for premarket review must demonstrate that it is safe and effective for its intended use. One of the most efficient ways to do this is by conforming to FDA recognized consensus standards. These standards represent agreed-upon state-of-the-art test methods, safety requirements, performance criteria, and process frameworks developed by expert technical committees around the world. When you conform to a recognized standard and submit a Declaration of Conformity, the FDA can rely on that conformance to satisfy certain premarket review requirements — reducing the amount of supporting data you need to provide and streamlining the review process.

Despite this, many manufacturers misunderstand how the recognition program works, which standards apply to their devices, and how to properly document conformance. Missteps here lead to FDA requests for additional information, delayed clearance or approval timelines, and in the worst cases, rejected submissions.

This guide covers the full landscape of FDA recognized consensus standards: how they are recognized, which ones matter most, how to use them in premarket submissions, and how to avoid the most common pitfalls. The mechanics below remain current. Recognition List Number 065 (effective February 19, 2026) is no longer the latest list: FDA published Recognition List Number 066 on August 24, 2026.

What Are FDA Recognized Consensus Standards?

Definition and Legal Basis

Consensus standards are voluntary technical standards developed by Standards Development Organizations (SDOs) through a process of open consultation, public comment, and consensus among stakeholders. They are not regulations. They are not mandatory unless a standard is specifically incorporated by reference into a federal regulation. Instead, they represent a voluntary framework that the FDA has evaluated and determined to be suitable for use in premarket submissions.

The legal authority for the FDA's standards recognition program comes from Section 514(c)(1)(B) of the Federal Food, Drug, and Cosmetic Act (FD&C Act). This provision directs the FDA to periodically publish in the Federal Register a list of recognized consensus standards. When a manufacturer submits a Declaration of Conformity to a recognized standard, the FDA may rely on that declaration to satisfy certain premarket requirements under the statute.

Key points that manufacturers often misunderstand:

• Recognition is voluntary. You are not required to conform to recognized standards. You may choose alternative approaches, but you then bear the burden of demonstrating that your approach is equally rigorous.

• Over 1,800 standards are currently recognized. The FDA maintains a searchable database of all recognized standards, organized by device specialty and standard type.

• Conformance can reduce the data burden. When you declare conformity to a recognized standard, the FDA can rely on that conformance to satisfy specific review requirements, meaning you may need to submit less supporting test data.

• Not all consensus standards are recognized. The FDA evaluates each standard and determines whether to recognize it, in whole or in part, for use in medical device premarket submissions.

• ISO 13485 is a notable exception. Despite being the most widely referenced quality management system standard in the medical device industry, ISO 13485 is not recognized by the FDA for standard premarket submissions. It is recognized only under the Medical Device Single Audit Program (MDSAP). The FDA's quality system requirements are defined by 21 CFR Part 820, which is transitioning to the Quality Management System Regulation (QMSR).

How Recognition Differs From Regulation

Understanding the distinction between a recognized standard and a regulatory requirement is essential:

The FDA Standards Recognition Program

Organization and Governance

The FDA's standards recognition program is managed by the Division of Standards and Conformity Assessment (DSCA), which operates within the Center for Devices and Radiological Health (CDRH). The program is known as the Standards Recognition and Conformity Assessment Program (S-CAP).

DSCA is responsible for:

• Evaluating consensus standards for potential recognition

• Managing the recognition list publication process

• Maintaining the searchable database of recognized standards

• Coordinating with Specialty Task Groups (STGs) that provide technical expertise on standards relevant to specific medical device categories

• Supporting the Accreditation Scheme for Conformity Assessment (ASCA) pilot program

Recognition List Publication Process

The FDA publishes updated lists of recognized consensus standards approximately twice per year in the Federal Register. Each recognition list includes additions of newly recognized standards, withdrawals of standards that are no longer appropriate, corrections to previously published information, and revisions to the scope of recognition for existing standards.

The recent cadence of recognition lists:

An important practical detail: the FDA updates its searchable database of recognized standards as decisions are made, even before the formal Federal Register publication. This means that between publication dates, manufacturers can check the database for newly recognized standards. While early adoption carries some risk (the formal notice has not been published), it also provides a strategic advantage for manufacturers who want to align with the latest requirements ahead of competitors.

How Standards Are Evaluated for Recognition

The FDA does not automatically recognize every consensus standard published by an SDO. Each standard undergoes an evaluation process that considers:

1. Relevance to medical device premarket review. Does the standard address a safety or performance concern that FDA reviewers evaluate?

2. Scientific and technical validity. Are the test methods, acceptance criteria, and process requirements based on sound science?

3. Applicability to the FD&C Act. Does the standard help satisfy a requirement under the Act?

4. No conflict with existing regulations. The recognized standard must not conflict with any FDA regulation.

5. Stakeholder input. The FDA considers comments from manufacturers, SDOs, healthcare professionals, and the public.

Recognition List 065 (February 2026) Updates

Recognition List Number 065, effective February 19, 2026, is the most recent update to the FDA's list of recognized consensus standards. This list is particularly relevant for manufacturers of medical electrical equipment and systems that rely on IEC 60601 and ISO/IEC 80601 series standards.

Key Updates in List 065

• Updated IEC standards for medical electrical equipment. Several standards in the IEC 60601 series received recognition updates, including revised editions and amended versions that reflect the latest safety and performance requirements for medical electrical systems.

• Updated ISO/IEC 80601 series. Particular requirements standards for specific types of medical equipment (patient monitors, ventilators, surgical equipment, etc.) were updated to reflect new editions.

• Transition periods for superseded standards. Where new editions replace previously recognized versions, transition periods have been established to allow manufacturers time to update their testing and documentation. For example, IEC 60601-2-52 Edition 1.0 has been superseded by Edition 1.1, with a transition period extending until July 5, 2026.

• Corrections and scope clarifications. Several previously recognized standards received corrections to their recognition scope or supplementary information sheets.

What This Means for Manufacturers

For manufacturers currently preparing premarket submissions, Recognition List 065 offers both opportunities and obligations:

• Newly recognized standards can be referenced immediately in Declarations of Conformity. If a new edition of a standard relevant to your device has been recognized, you can begin testing to that edition right away.

• Early alignment provides a strategic advantage. Manufacturers who proactively update their testing and documentation to conform to newly recognized standards demonstrate state-of-the-art compliance, which tends to result in smoother FDA reviews.

• Transition periods must be tracked. If a standard you currently conform to has been superseded, you need to plan your migration to the new edition within the specified transition period. After the transition deadline, Declarations of Conformity to the old edition will no longer be accepted.

• The searchable database is your primary tool. Always verify the current recognition status of a standard in the FDA's database before referencing it in a submission, rather than relying on potentially outdated printed lists.

Key Standards Development Organizations

The FDA recognizes standards from multiple Standards Development Organizations. Understanding who develops these standards helps you navigate the landscape and find the right standards for your device. The following table lists the primary SDOs whose standards are recognized by the FDA:

A practical point: many standards exist in multiple forms. For example, IEC 60601-2-47 (particular requirements for the basic safety and essential performance of ambulatory electrocardiographic systems) also exists as ANSI/AAMI/IEC 60601-2-47, which is the U.S. adoption. The FDA's recognition list specifies which version(s) are recognized. When a U.S. adoption exists, it is typically the recognized version, even though the technical content may be identical to the IEC original.

Most Important Recognized Standards

While the FDA recognizes over 1,800 standards, a relatively small number are referenced in the vast majority of premarket submissions. The following table summarizes the most important recognized standards, what they cover, and when they apply:

Important Note on ISO 13485

ISO 13485 (Medical devices — Quality management systems) is conspicuously absent from the list above. This is intentional and reflects an important nuance. The FDA does not recognize ISO 13485 for use in standard premarket submissions (510(k), De Novo, PMA, etc.). The FDA's quality system requirements are defined by 21 CFR Part 820, which is being modernized as the Quality Management System Regulation (QMSR). ISO 13485 is recognized only under the Medical Device Single Audit Program (MDSAP), where a single audit conducted by an Auditing Organization can satisfy the quality system requirements of multiple regulatory jurisdictions simultaneously.

This distinction matters because some manufacturers incorrectly assume that ISO 13485 certification can be referenced in a Declaration of Conformity for a 510(k) or PMA submission. It cannot — at least not for the purpose of satisfying FDA quality system requirements in a premarket context.

Specialty Task Groups Explained

The FDA uses Specialty Task Groups (STGs) to provide technical expertise on standards relevant to specific medical device categories. Each STG is composed of engineers, scientists, and reviewers who specialize in a particular area of medical technology. STGs evaluate proposed standards, recommend recognition decisions, and help identify gaps in the existing standards landscape.

Understanding which STG covers your device can help you anticipate which standards will be relevant to your submission and which test methods FDA reviewers will expect to see. The current STGs and their areas of responsibility:

When a new standard is proposed for recognition, the relevant STG reviews it and makes a recommendation to DSCA. The STG's technical evaluation considers whether the standard's test methods are scientifically valid, whether its acceptance criteria are appropriate for the intended regulatory purpose, and whether it addresses a genuine need in premarket review.

Declaration of Conformity: Complete Process

The Declaration of Conformity (DOC) is the formal document by which a manufacturer declares that its device conforms to a specific FDA recognized consensus standard. Submitting a DOC is not merely a procedural checkbox — it is a legally significant statement that the FDA relies upon during premarket review.

When to Submit a Declaration of Conformity

You should submit a DOC when all of the following conditions are met:

1. The standard is currently recognized by the FDA (verify in the searchable database).

2. Your device fully conforms to the standard, or you can justify any deviations.

3. The standard is applicable to the regulatory requirements being addressed in your submission.

4. All testing has been performed on the finished device (or at the stage of manufacture appropriate for the test).

Required Elements of a Declaration of Conformity

A complete DOC must include the following elements:

The DOC in Practice: eSTAR and Form FDA 3514

For 510(k) and De Novo submissions prepared using the eSTAR template (which is now the required format for most submissions), the standards conformance information is built into the template. eSTAR automatically generates a standards table where you list each recognized standard you conform to, and the DOC PDFs are uploaded directly within the template.

For other submission types, the standards information is captured on the CDRH Premarket Review Submission Cover Sheet (Form FDA 3514), which includes a section for listing recognized standards and accompanying Declarations of Conformity.

Full Conformity vs. Partial Conformity

Full conformity means that the device meets every requirement of the recognized standard, with no exceptions. This is the expected case for most Declarations of Conformity. When you declare full conformity, the FDA can rely on the DOC to satisfy the corresponding premarket review requirements without requesting additional test data.

Partial conformity means that the device meets some but not all requirements of the standard, or that it conforms with certain deviations or exclusions. Partial conformity requires you to:

• Clearly identify which requirements are not met

• Provide a technical justification for each deviation

• Submit additional test data or analysis to demonstrate that the deviation does not compromise safety or effectiveness

• Expect that the FDA will evaluate the non-conforming aspects on their merits

Partial conformity can be appropriate in certain situations — for example, when a particular test method in the standard is not applicable to your device's design or intended use. However, it significantly increases the scrutiny applied to your submission and should be avoided when possible.

General Use: An Alternative to Declaration of Conformity

Not all standard references in a premarket submission require a DOC. The FDA distinguishes between two categories:

Under the General Use category, you can reference any standard — including non-recognized standards — but you cannot submit a DOC. Instead, you submit the underlying test data and reports that demonstrate your device's performance. The FDA will evaluate the data on its merits, without the presumption of adequacy that comes with conformance to a recognized standard.

This distinction is critical: you cannot submit a Declaration of Conformity to a non-recognized standard. If you choose to test to a standard that the FDA has not recognized, you must submit your test data under General Use, and the FDA will assess whether the testing is sufficient.

Legal and Ethical Considerations

A Declaration of Conformity is a serious legal document. The FDA considers a false DOC to be a falsified document, which can result in enforcement action, including warning letters, import alerts, consent decrees, and civil or criminal penalties. A DOC must accurately reflect the device's actual conformance status, supported by verifiable test data and documentation.

Key rules:

• You cannot submit a DOC to a standard that has been withdrawn or superseded (unless within a transition period).

• You cannot submit a DOC to a non-recognized standard.

• All testing referenced in the DOC must have been actually performed on the finished device (or at the appropriate stage of manufacture).

• The DOC must be signed by an authorized representative of the manufacturer.

How to Use Standards in 510(k), De Novo, and PMA Submissions

Applicable Submission Types

FDA recognized consensus standards can be referenced in a wide range of premarket submission types:

Standards in 510(k) Submissions

In a 510(k) submission, recognized standards serve a dual purpose. First, they help establish that your device is substantially equivalent to the predicate device by demonstrating that both devices meet the same safety and performance standards. Second, they reduce the data burden by allowing you to rely on DOCs rather than submitting extensive raw test data.

The eSTAR template for 510(k) submissions includes a dedicated section for recognized standards. For each standard you reference, you will:

1. Select the standard from a pre-populated list (based on the FDA's current recognition database)

2. Indicate whether you are submitting a DOC (full conformity) or using the standard under General Use

3. Upload the DOC PDF or supporting test reports as appropriate

4. Identify the extent of conformity and any deviations

Standards in De Novo Submissions

De Novo classification requests present a unique opportunity for standards-based strategies. When the FDA grants a De Novo request, it creates a new classification regulation and establishes special controls for that device type. These special controls frequently include conformance to specific recognized consensus standards.

As a De Novo applicant, you can proactively propose which standards should serve as special controls for the new device type. This gives you significant influence over the regulatory framework for your device category. By demonstrating conformance to relevant standards in your submission, you both strengthen your own application and help shape the expectations for future manufacturers in the same category.

Standards in PMA Submissions

PMA submissions require the most comprehensive evidence of safety and effectiveness. While recognized standards alone are insufficient for PMA approval (clinical data is typically required), they play an important supporting role:

• Non-clinical testing: Standards such as IEC 60601, ISO 10993, and ISO 11137 provide the framework for bench testing, biocompatibility evaluation, and sterilization validation.

• Manufacturing quality: Standards for process validation, sterilization, and packaging help demonstrate manufacturing control.

• Risk management: ISO 14971 provides the risk management framework that underpins the entire PMA application.

Transition Periods and Superseded Standards

How Transition Periods Work

When the FDA recognizes a new edition of a standard that supersedes a previously recognized edition, the old edition does not immediately become invalid. Instead, the FDA typically establishes a transition period during which manufacturers may continue to submit DOCs to either the old or the new edition.

The transition period serves several purposes:

• It allows manufacturers time to update their testing programs and documentation to the new edition.

• It prevents disruption to submissions that are already in preparation.

• It gives testing laboratories time to update their capabilities and accreditations.

Example: IEC 60601-2-52 Transition

A concrete example from Recognition List 065 illustrates how this works in practice. IEC 60601-2-52 Edition 1.0 (particular requirements for the basic safety and essential performance of medical beds) has been superseded by Edition 1.1. The FDA has established a transition period extending until July 5, 2026. During this period:

• Manufacturers may submit DOCs to either Edition 1.0 or Edition 1.1.

• After July 5, 2026, DOCs to Edition 1.0 will no longer be accepted.

• Manufacturers should plan to complete any testing to Edition 1.0 and submit their documentation before the transition deadline, or update their testing to Edition 1.1.

What Happens to Cleared and Approved Devices

An important principle: devices that have been cleared or approved under a previous edition of a standard remain valid even after that standard edition is withdrawn. The FDA does not require manufacturers to re-test or re-submit devices simply because a standard has been updated.

However, manufacturers should be aware of the following:

• Post-market obligations (such as complaints, CAPA, and risk management) may drive the need to evaluate devices against new standards editions, even for previously cleared products.

• Significant changes to a cleared device (requiring a new 510(k)) will need to conform to the currently recognized edition of applicable standards.

• State-of-the-art expectations evolve with new standards editions, and this can affect the FDA's expectations during inspections and post-market reviews.

Common Mistakes to Avoid

Over years of observing submissions, several recurring mistakes stand out. Avoiding these will save significant time and resources:

1. Referencing Withdrawn or Superseded Standards

This is the single most common mistake. Manufacturers sometimes reference standard editions that have been superseded or withdrawn, often because they are using outdated templates or have not checked the FDA's searchable database recently. Always verify the current recognition status of every standard you reference before submitting.

2. Submitting a DOC to a Non-Recognized Standard

A Declaration of Conformity can only be submitted for FDA recognized consensus standards. If you test to a standard that is not on the recognition list, you must submit your test data under the General Use category. Submitting a DOC to a non-recognized standard will result in an FDA refusal to accept or a request for additional information.

3. Testing on Non-Finished Devices

All testing referenced in a Declaration of Conformity must be performed on the finished device, unless the standard specifically allows testing at an earlier stage of manufacture. Testing on prototypes, engineering samples, or incomplete assemblies does not satisfy DOC requirements.

4. Claiming Full Conformity With Known Deviations

If your device does not fully conform to a standard, you must disclose the deviations. Claiming full conformity when deviations exist is a false declaration, which the FDA treats as a serious compliance issue.

5. Ignoring Supplementary Information Sheets

The FDA sometimes publishes Supplementary Information Sheets (SIS) alongside recognized standards. These sheets specify the scope of recognition, any limitations, and additional guidance on how the standard should be applied. Ignoring the SIS can lead to misapplication of the standard and submission deficiencies.

6. Failing to Track Transition Periods

If a standard you conform to has been superseded, you must complete your submission within the transition period or update your conformance to the new edition. Failing to track these deadlines can result in a submission that references a no-longer-accepted standard edition.

7. Confusing ISO 13485 Recognition Scope

ISO 13485 is recognized only under MDSAP, not for standard premarket submissions. Do not submit a DOC to ISO 13485 in a 510(k), De Novo, or PMA submission for the purpose of demonstrating quality system compliance.

8. Not Aligning Standards With Risk Management

Standards conformance should be documented within the framework of your risk management file (ISO 14971). Failure to connect standard conformance to hazard identification, risk analysis, and risk control can create gaps that auditors and reviewers will identify.

Step-by-Step: Incorporating Standards Into Your Submission

The following step-by-step process will help you systematically identify, apply, and document standards conformance in your premarket submission.

Step 1: Identify Applicable Standards Early

Begin standards identification during the concept phase of your device development. Consider:

• The device type and classification (which STG covers your device?)

• The device's technology (electrical, mechanical, software, combination?)

• Patient contact type and duration (which biocompatibility endpoints?)

• Sterilization method (which sterilization standards?)

• Intended use environment (hospital, home, ambulatory — affects EMC and safety requirements)

• Software content (which software lifecycle and usability standards?)

Step 2: Verify Recognition Status

For each potentially applicable standard, check the FDA's searchable database of recognized consensus standards. Verify:

• Is the standard currently recognized?

• Which edition or version is recognized?

• Are there any Supplementary Information Sheets?

• Is the standard within a transition period?

Record the recognition number and publication date for your records.

Step 3: Develop a Standards Matrix

Create a standards matrix that maps each recognized standard to the specific premarket requirements it addresses. This matrix serves as both an internal planning tool and a submission document. Include:

Step 4: Conduct Testing

Perform all testing required by the standards on the finished device (or at the appropriate stage of manufacture). Ensure that:

• Test methods exactly follow the standard's prescribed methods

• Test equipment is calibrated and qualified

• Testing is conducted by qualified personnel

• All results are documented in test reports that can withstand FDA review

• If using an external test laboratory, verify that the laboratory is competent and, where applicable, accredited

Step 5: Prepare Declarations of Conformity

For each standard where you achieve full conformance, prepare a Declaration of Conformity that includes all required elements:

1. Standard identification (full designation, edition, publication date)

2. Device identification (model numbers, configurations covered)

3. Extent of conformance (full or partial)

4. Description of any deviations, with technical justification

5. Summary of test results

6. Identity of the testing laboratory

7. Date(s) of testing

8. Name, title, and signature of the authorized representative

Step 6: Integrate Into Submission

Using eSTAR (for 510(k) and De Novo) or the appropriate submission format, integrate your standards information:

• Complete the standards table with all referenced standards

• Upload DOC PDFs for fully conformant recognized standards

• Upload test reports for General Use references

• Cross-reference standards conformance in your substantial equivalence discussion (510(k)) or safety and effectiveness summary (De Novo/PMA)

Step 7: Review and Verify

Before submitting, conduct a final review:

• Confirm that all referenced standards are currently recognized

• Verify that all DOCs are complete and signed

• Ensure that test data supports the conformance claims in each DOC

• Check that the standards matrix is consistent with the submission content

• Verify no transition period deadlines will expire during the expected review period

The ASCA Pilot Program

The Accreditation Scheme for Conformity Assessment (ASCA) is an FDA pilot program that adds an additional layer of confidence to testing results. Under ASCA, the FDA accredits testing laboratories to perform conformance testing for specific recognized standards. When testing is performed by an ASCA-accredited laboratory, the FDA has greater confidence in the test results, which can further streamline the review process.

Key features of the ASCA program:

• Voluntary participation. Manufacturers are not required to use ASCA-accredited laboratories, but doing so can provide regulatory benefits.

• Scope-limited. Not all recognized standards are included in the ASCA program. The FDA has identified specific standards for which ASCA accreditation is available.

• Laboratory accreditation. Testing laboratories must meet ASCA requirements and undergo FDA assessment to receive accreditation.

• Enhanced review efficiency. Test reports from ASCA-accredited laboratories may receive reduced scrutiny during premarket review, as the laboratory's competence has been independently verified.

For manufacturers with complex testing requirements (such as extensive electrical safety or EMC testing), using an ASCA-accredited laboratory can be a strategic advantage that reduces the likelihood of FDA questions about test methodology or results.

Strategic Benefits of Standards Conformance

Beyond the immediate regulatory benefits, systematic conformance to FDA recognized consensus standards provides several strategic advantages:

Reduced Submission Data Burden

The most direct benefit: when you conform to a recognized standard and submit a DOC, the FDA can rely on that conformance to satisfy specific premarket requirements. This means you may not need to submit the full underlying test data, reducing the volume of your submission and the time reviewers need to spend evaluating it.

Streamlined Review Process

FDA reviewers are familiar with recognized standards and their requirements. When a submission demonstrates conformance to well-known standards, reviewers can quickly confirm that key safety and performance requirements are met, rather than evaluating novel or unfamiliar test methods and criteria.

State-of-the-Art Demonstration

Conformance to current editions of recognized standards demonstrates that your device incorporates state-of-the-art safety and performance features. This is particularly important for De Novo submissions, where you are establishing the baseline expectations for a new device category.

Global Regulatory Alignment

Most FDA recognized consensus standards are international standards (ISO, IEC) that are also referenced by regulatory authorities in the EU, Japan, Canada, Australia, and other markets. Designing and testing to these standards supports simultaneous submissions in multiple jurisdictions, reducing duplicative testing and accelerating global market access.

Audit and Inspection Readiness

Standards conformance documentation supports quality system audits and FDA inspections. When an investigator asks about risk management, biocompatibility, or electrical safety, being able to point to systematic conformance to recognized standards provides clear, defensible evidence of your approach.

De Novo Special Controls Framework

For De Novo submissions, recognized standards can serve as the foundation for special controls. By proposing specific standards conformance as special controls, you help the FDA define the regulatory framework for your device type, which benefits both your company and future manufacturers in the same category.

FAQ

How often does the FDA update its list of recognized consensus standards?

The FDA publishes updated recognition lists approximately twice per year in the Federal Register. However, the searchable database is updated on a rolling basis as recognition decisions are made, even before the formal Federal Register publication. Manufacturers should check the database regularly — ideally before each submission — to verify the current recognition status of their referenced standards.

Is conformance to recognized standards mandatory?

No. Conformance to recognized consensus standards is voluntary unless a standard has been specifically incorporated by reference into a federal regulation. However, if you choose not to conform to a recognized standard, you must provide alternative evidence that satisfies the relevant premarket requirements. This typically means submitting more test data and facing a more detailed review.

Can I submit a Declaration of Conformity to a standard that is not recognized by the FDA?

No. A Declaration of Conformity can only be submitted for standards that are currently recognized by the FDA. If you test to a non-recognized standard, you can reference it under the General Use category and submit your test data and reports, but you cannot submit a DOC.

What happens if I conform to an older edition of a standard that has been superseded?

If the FDA has established a transition period for the superseded edition, you may continue to submit a DOC to the old edition until the transition deadline expires. After the transition period, DOCs to the old edition will no longer be accepted. You should plan to update your testing and documentation to the new edition before the deadline.

Does conformance to a recognized standard guarantee FDA clearance or approval?

No. Conformance to recognized standards satisfies specific technical requirements but does not guarantee clearance or approval. The FDA considers the totality of the evidence in a premarket submission, including clinical data (where required), labeling, manufacturing information, and other factors. Standards conformance is one component of a successful submission, not a substitute for a complete application.

Can I use test data from a previous submission for a new device?

It depends. Test data from standards conformance testing may be applicable to a new device if the new device is sufficiently similar to the previously tested device and the testing remains valid. However, significant design changes, different configurations, or new intended uses may require re-testing. The eSTAR template allows you to reference previously submitted test data where appropriate, but you must justify its applicability to the new device.

Is ISO 13485 recognized by the FDA?

ISO 13485 is recognized by the FDA only under the Medical Device Single Audit Program (MDSAP). It is not recognized for standard premarket submissions such as 510(k), De Novo, PMA, or IDE. The FDA's quality system requirements are defined by 21 CFR Part 820, which is transitioning to the Quality Management System Regulation (QMSR). Do not submit a DOC to ISO 13485 in a standard premarket submission.

What is the difference between Declaration of Conformity and General Use?

A Declaration of Conformity (DOC) is submitted when your device fully conforms to a recognized standard. Under General Use, you reference a standard (recognized or non-recognized) but do not submit a DOC — instead, you submit the underlying test data and reports. General Use is appropriate when you have partial conformity to a recognized standard, or when you are using a non-recognized standard.

How do I find the right standards for my device?

Start by identifying the Specialty Task Group (STG) that covers your device type. Then search the FDA's database of recognized standards, filtering by the relevant STG and device category. Review the product code for your device, which the FDA's database associates with applicable standards. Finally, review guidance documents for your device type, which often reference applicable standards. If you are unsure, a pre-submission meeting with the FDA can help clarify which standards are expected.

What is the ASCA program and should I use it?

The Accreditation Scheme for Conformity Assessment (ASCA) is an FDA pilot program that accredits testing laboratories to perform conformance testing for specific recognized standards. Using an ASCA-accredited laboratory provides additional confidence in your test results and can streamline the FDA review process. Participation is voluntary, but it is a strategic consideration for manufacturers with complex testing requirements. Check whether ASCA accreditation is available for the standards applicable to your device.

Can a Declaration of Conformity be submitted for software standards like IEC 62304?

Yes. IEC 62304 is a recognized consensus standard, and you can submit a DOC to it. However, demonstrating conformance to IEC 62304 is fundamentally different from demonstrating conformance to a physical test standard. For IEC 62304, conformance is demonstrated through process documentation, design artifacts, and lifecycle records rather than physical test results. Your DOC should describe the extent of your lifecycle process conformance and reference the supporting documentation in your submission.

What should I do if a standard I need is not recognized?

If a standard you believe is relevant to your device is not recognized by the FDA, you can still use it — but under the General Use category. Submit your test data and reports, and explain why the standard is appropriate for demonstrating your device's safety and performance. You can also petition the FDA to consider recognizing the standard through the standards recognition process. Contact the DSCA or the relevant STG to express your interest.
