The Defense Technical Information Center is the largest central resource for DoD and government-funded scientific, technical, engineering, and business related information and is an excellent complement or back-up to ASSIST tools. This site offers an easy to use link to the full text DoD Specifications and Standards eAccess database.
Standards Issued or Adopted by Federal Agencies
In accordance with the NTTAA, regulatory agencies adopt private sector standards, wherever possible, instead of creating proprietary, non-consensus standards. Standards.gov is NIST's federal standards portal, featuring background materials and useful links for locating information about the use of standards in government.
NIST's Standards Incorporated by Reference (SIBR) database contains the voluntary consensus standards, government unique standards, private industry standards, and international standards that are referenced in the U.S. Code of Federal Regulations (CFR), which codifies all Federal regulations in the United States. SIBR also includes standards that are used by U.S. Federal Government Agencies in procurement activities.
Many government agencies offer databases and websites that aggregate and track their standards requirements and programs:

The NHTSA safety requirements are set forth in the series of Federal Motor Vehicle Safety Standards.
National Science and Technology Council (NSTC)
NSTC publishes the "Registry of USG Recommended Biometric Standards". This Registry is based upon interagency consensus on biometric standards required to enable the interoperability of various Federal biometric applications, and to guide Federal agencies as they develop and implement related biometric programs.
Consumer Product Safety Commission (CPSC)

There are thousands of Industry Standards in the U.S. developed by professionals in specific industry sectors such as telecommunications, concrete, fire protection, information technology, etc. Many industry sector standards are included in the standards search engines provided by NSSN, IHS, TechStreet, and SAI Global.
However, when looking for standards it is useful to also search a standards developer's site. There are over 600 standards developers based in the U.S., many of which are international in scope and participation.
View and add to our list of standards organizations that offer free access to their standards.
There are a diversity of bodies involved in the preparation of standards used globally. These include governmental or treaty organizations, nongovernmental organizations, and organizations that are either specialized in standardization or involved in other activities. In general, an international standard is voluntary and has no legal status unless a regulatory authority requires conformance to that standard.
It is the policy of the U.S. government to use the term "international standard" to refer to standards developed in conformity with the principles of the WTO TBT Committee's 2000 Decision on the Principles for the Development of International Standards, which include (1) openness; (2) transparency; (3) impartiality and consensus; (4) relevance and effectiveness; (5) coherence; and (6) the development dimension.
Though many standards developers in the United States are international in scope and participation, there are several international standards bodies that operate by national representative participation, including:
The ISO supports a wide-range of standardization work on everything from screw threads to ship building.
The IEC prepares and publishes international standards for electrical, electronic and related technologies.
ITU's scope of standardization is global telecommunications. ITU's standards documents, called Recommendations, can be downloaded for free on the ITU website.
Codex develops food standards, guidelines and related texts
Non-U.S. National Standards
If you are an exporter, it is important to know the national standards and regulations that must be addressed to gain entry to a new market. Within each country, the designated Inquiry Point to the WTO/TBT Agreement is prepared to assist you in identifying the pertinent standards and regulations that apply to the product or service you offer.
Listed below are links to several national standards bodies that offer searchable standards collections in English. Many of the country pages on our World Guide to Standards Resources have links to the country's national standards body as well. Another good source for information on national standards bodies is the ISO membership directory, which lists the over 150 member bodies and counting.
