Approval of an American National Standard requires verification by ANSI that the
requirements for due process, consensus, and other criteria for approval have been
met by the standards developer
Consensus is established when, in the judgment of the ANSI Board of Standard
Review, substantial agreement has been reached by directly and materially affected
interests. ubstantial agreement means much more than a simple majority, but not
necessarily unanimity. Consensus requires that all views and objections be
considered, and that a concerted effort be made toward their resolution
The use of American National Standards is completely voluntary their existence does
not in any respect preclude anyone, whether he has approved the standards or not
from manufacturing, marketing, purchasing, or using products, processes, or
procedures not conforming to the standards
