Copying and networking prohibited.Approval of an American National Standard requires verification by ANSI that therequirements for due process, consensus, and other criteria for approval have been metby the standards developer.Consensus is established when, in the
3、 judgement of the ANSI Board of StandardsReview, substantial agreement has been reached by directly and materially affected inter-ests. Substantial agreement means much more than a simple majority, but not necessari-ly unanimity. Consensus requires that all views and objections be considered, and th
4、at aconcerted effort be made toward their resolution.The use of American National Standards is completely voluntary; their existence doesnot in any respect preclude anyone, whether he has approved the standards or not, frommanufacturing, marketing, purchasing, or using products, processes, or proced
5、ures notconforming to the standards.The American National Standards Institute does not develop standards and will in no cir-cumstances give an interpretation of any American National Standard. Moreover, noperson shall have the right or authority to issue an interpretation of an American NationalStan
