FDA Modernization Act of 1997: Guidance for the Recognition and 
Use of Consensus Standards; Availability

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is: (1) Announcing the 
availability of a guidance entitled ``Guidance on the Recognition and 
Use of Consensus Standards,'' the purpose of which is to provide 
guidance to industry and reviewers within the Center for Devices and 
Radiological Health (CDRH) on the use of recognized consensus 
standards, including declarations of conformity to the standards, 
during the evaluation of premarket submissions for medical devices; (2) 
publishing the initial list of standards that will be recognized for 
use in the premarket review process; and (3) announcing the agency's 
policy on updating the list of recognized standards. This guidance will 
assist manufacturers who elect to declare conformity with consensus 
standards to meet all or part of medical device review requirements.

DATES: This guidance is effective on February 19, 1998; however, 
written comments concerning this guidance may be submitted at any time.

ADDRESSES: Written comments concerning this guidance must be submitted 
to the first contact person listed below. Comments should be identified 
with the docket number found in brackets in the heading of this 
document. Submit written requests for single copies of ``Recognition 
and Use of Consensus Standards'' to the Division of Small Manufacturers 
Assistance (DSMA), Center for Devices and Radiological Health (HFZ-

SUPPLEMENTARY INFORMATION:

I. Background

    Many domestic and international consensus standards address 
relevant aspects of safety and/or effectiveness of medical devices. 
Many of these consensus standards have been developed with the 
participation of FDA staff. Section 204 of the Food and Drug 
Administration Modernization Act of 1997, Pub. L. 105-115, 111 Stat. 
2296 (1997) (FDAMA) amends section 514 of the Federal Food, Drug, and 
Cosmetic Act (the act) (21 U.S.C. 360d), allowing the agency to 
recognize consensus standards established by international and national 
standards development organizations that may be used to satisfy 
identified portions of device review requirements. This notice 
announces the availability of a guidance document entitled ``Guidance 
on the Recognition and Use of Consensus Standards,'' which describes 
how FDA will implement that part of the FDAMA.
    The agency has adopted Good Guidance Practices (GGP's), which set 
forth the agency's policies and procedures for the development, 
issuance, and use of guidance documents (62 FR 8961, February 27, 
1997). Although ``Guidance on the Recognition and Use of Consensus 
Standards'' is Level 1 guidance under the GGP's, this guidance will 
become effective upon issuance. Under the GGP's the agency may elect 
not to solicit public comment prior to implementation when there is a 
new statutory requirement * * * that requires immediate implementation 
and guidance is needed to help effect such implementation'' (62 FR 8961 
at 8968). However, comments may be submitted at any time by interested 
parties, and these comments will be considered in any future revisions 
to the guidance.
    This guidance document may contain collections of information that 
require OMB clearance under the Paperwork Reduction Act of 1995. FDA 
will seek such approval and provide an opportunity for comment, as 
appropriate.

II. Use of Recognized Standards

    A person required to submit a premarket application (i.e., 
Premarket Notification (510(k)), Investigational Device Exemptions 
application (IDE), Premarket Approval application (PMA), Humanitarian 
Device Exemption application (HDE), or Product Development Protocol 
(PDP)) must provide information as required by the statute and 
regulations to allow FDA to make an appropriate decision regarding the 
clearance or approval of the submission. This guidance document 
describes how FDA will recognize consensus standards and use 
conformance with recognized standards to satisfy review requirements. 
It does not affect FDA's ability to obtain any information authorized 
by the statute or regulations. Use of consensus standards in this 
manner is authorized by section 514 of the act, as amended by FDAMA.
    FDA believes that conformance with applicable recognized consensus 
standards can provide a reasonable assurance of safety and/or 
effectiveness for many devices. Therefore, information submitted on 
conformance with such standards will have a direct bearing on 
determinations of safety and effectiveness made during the review of 
IDE's, HDE's, PMA's, and PDP's. In case of 510(k)s, information on 
conformance with recognized consensus standards may help establish the 
substantial equivalence of a new device to a legally marketed predicate 
device. This information can serve as a surrogate for comparative 
information to show that the new device is as safe and effective as the 
predicate in the areas covered by the standards. Moreover, if a 
premarket submission contains a declaration of conformity to recognized 
consensus standards, this will, in most cases, eliminate the need to 
review actual test data for those aspects of the device addressed by 
the standards. The content of a declaration of conformity is described 
in the guidance document and is consistent with the ISO/IEC Guide 22.
    Conformance with recognized consensus standards in and of itself, 
however, may not always be a sufficient basis for regulatory decisions. 
For example, a specific device may raise a safety or effectiveness 
issue not addressed by any standard, or a specific FDA regulation may 
require additional information beyond that which conformity to the 
recognized consensus standards provides. Under such circumstances, 
conformity with recognized standards will not satisfy all requirements 
for marketing, or investigating, the product in the United States.
    The guidance document, ``Guidance on the Recognition and Use of 
Consensus Standards'', represents the agency's current thinking on the 
use of recognized consensus standards for medical devices. It does not 
create or confer any rights for or on any person and does not operate 
to bind FDA or the public. An alternative approach may be used if such 
approach satisfies the requirements of the applicable statute, 
regulations, or both.

III. List of Recognized Standards

    The initial list of consensus standards to be recognized for use in 
premarket review is presented at the end of this document. This list is 
also maintained on the FDA web site ``http://www.fda.gov/cdrh''. Also 
posted on the web site are supplemental data sheets for each recognized 
standard. These data sheets list the address(es) where the standard can 
be obtained, information on any limitations to the application of the 
standard in medical device review, and a list of devices for which 
declarations of conformity with the recognized standard will be 
routinely accepted by agency reviewers. In addition to these documents, 
the web site contains answers to frequently asked questions regarding 
the use of recognized standards.

IV. Recommendation of Standards for Recognition by FDA

    Modifications to the list of recognized consensus standards related 
to medical devices will be announced in the Federal Register at least 
once a year, or more often if necessary. FDA intends that the next 
revision to the list of recognized standards will include standards to 
be recognized by the Center for Biologics Evaluation and Research as 
well as by CDRH.
    Any person may recommend consensus standards as candidates for 
recognition under new paragraph  of section 514 of the act, 
by submitting such recommendations, with justification, to the address 
identified at the beginning of this document. To be properly 
considered, such recommendations should contain at a minimum the 
following information: (1) Title of the standard, (2) any reference 
number and date, (3) name and address of the nationally or 
internationally recognized standards development organization, (4) a 
proposed list of devices for which a declaration of conformity should 
routinely apply, and (5) a brief identification of the testing or 
performance or other characteristics of

[[Page 9563]]

the device(s) that would be addressed by a declaration of conformity.
