5、RDApproval of an American National Standard requires verification by ANSI that the require-ments for due process, consensus, and other criteria for approval have been met by the stan-dards developer.Consensus is established when, in the judgement of the ANSI Board of Standards Review, substantial ag
6、reement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not neces-sarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution.The use of
7、 American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he or she has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards.The American Nati
8、onal Standards Institute does not develop standards and will in no cir-cumstances give an interpretation of any American National Standard. Moreover, no per-son shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standard
9、s Institute. Requests for interpre-tations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard.CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute requ
10、ire that action be taken periodically to reaffirm, revise, or withdraw this standard.
