Standards Incorporated by Reference (SIBR) Database

The Standards Incorporated by Reference (SIBR) Database includes the voluntary consensus standards, government unique standards, private industry standards, and international standards referenced in the Code of Federal Regulations (CFR) and those used by U.S. Federal Government Agencies in their procurement activities.

The Code of Federal Regulations (CFR) is the codification of the general and permanent rules published in the Federal Register by the executive departments and agencies of the Federal Government. It is divided into 50 titles that represent broad areas subject to Federal regulation. Each volume of the CFR is updated once each calendar year and is issued on a quarterly basis. More data on the CFR can be found at the GPO Access Home Page.

In this database, Regulatory Standards Incorporated by Reference are sometimes referred to as as R-SIBR and Procurement Standards Incorporated by Reference as P-SIBR.

This database is continually being updated as the CFR changes, procurement policy, requirements, and standards change, and new standards are incorporated. If you find any errors, ommissions, or want a new standard to be considered, then please notify the SIBR Administrator at sibr@nist.gov using the Contact Us link.
