e acceptance of a standard as an American National Standard (ANS) requires that it be processed through one of three methods: by canvass list, accredited standards committee (ASC), or accredited standards organization action. All three methods share the common requirement that the process used has been accredited by the American National Standards Institute (ANSI) that the methodology incorporates due process and that consensus among interests is achieved. Inherent in that approval is presentation of accepted operational procedures and/or a balloting group that is balanced among users, manufacturers, and general interest groups. Other considerations include (1) that the document is within the scope previously registered, (2) identi–ed con«icts are resolved, and (3) that known national standards were examined to avoid duplication or con«ict, any appeal has been completed, and the ANSI patent policy is met.
