A standard, as defined by the National Standards Policy Advisory Committee, is:
"A prescribed set of rules, conditions, or requirements concerning definitions of terms; classification of components; specification of materials, performance, or operations; delineation of procedures; or measurement of quantity and quality in describing materials, products, systems, services, or practices."
As the U.S. member body of the International Organization for Standardization (ISO), ANSI has been authorized to provide, upon request, complimentary access for students and faculty to selected standards currently available in the ISO collection. Certain standards from the International Electrotechnical Commission (IEC) may also be made available upon request. These collections are comprised of nearly 20,000 standards, which can be made available to U.S. faculty and students in all disciplines in institutions of higher learning throughout the United States.
The American Dental Association (ADA) has also authorized access to a collection of dental standards upon request.
