Domestic Programs (American National Standards) Overview
Accreditation by ANSI signifies that the
procedures used by the standards body in connection with the development of
American National Standards meet the Institute’s essential requirements for
openness, balance, consensus and due process.
ANSI is often asked about the total number of
standards (and standards setting bodies) in the United States. It is estimated that in the U.S. today there
are hundreds of “traditional” standards developing organizations – with the 20
largest SDOs producing 90% of the standards – and hundreds more
“non-traditional” standards development bodies, such as consortia. This means that the level of U.S.
participation is quite expansive as the groups themselves are comprised of
individual committees made up of experts addressing the technical requirements
of standards within their specific area of expertise.
As of 2012, some 226 of these standards developers were accredited by ANSI; there are approximately 10,000 American National Standards (ANS).
According to data provided in NIST Special Publication 806, Standards
Activities of Organizations in the United States (1996 Edition; edited by
Robert B. Toth), there are more than 93,000 standards produced and nearly 700 
organizations that cited standards development as an area of activity. Of these, the federal government is the
largest single creator and user of standards (more than 44,000 of them); the
private sector in America collectively has about 49,000 standards.
However, with the approval of the National
Technology Transfer and Advancement Act (NTTAA) of 1995 (Public Law 104-113),
federal agencies are encouraged to utilize voluntary consensus standards where
feasible and to participate as appropriate in voluntary consensus standards
development activities. Standards that
are approved as American National Standards satisfy all of the requirements of
The ANS process is designed to withstand
scrutiny, while protecting the rights and interests of every participant. In
essence, ANSs quicken the market acceptance of products while making clear how
to improve the safety of those products for the protection of consumers.
The hallmarks of the American National Standards process include:
- consensus on a proposed standard by a group or
"consensus body" that includes representatives from materially
affected and interested parties;
- broad-based public review and comment on draft
- consideration of and response to comments
submitted by voting members of the relevant consensus body and by public review
- incorporation of approved changes into a draft
- right to appeal by any participant that believes
that due process principles were not sufficiently respected during the
standards development in accordance with the ANSI-accredited procedures of the
As mentioned above, in order to maintain ANSI
accreditation, standards developers are required to consistently adhere to a
set of requirements or procedures that govern the consensus development
process. These requirements are set forth in a document known as the
"ANSI Essential Requirements".
A series of guidance documents help to further explain these procedures.
Due process is the key to ensuring that ANSs are
developed in an environment that is equitable, accessible and responsive to the
requirements of various stakeholders. The open and fair ANS process ensures
that all interested and affected parties have an opportunity to participate in
a standard's development. It also serves and protects the public interest since
standards developers accredited by ANSI must meet the Institute's essential
requirements and other due process safeguards.
