Consensusisestablishedwhen,inthejudgmentoftheANslBoardofStandards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be 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 procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard.
