3、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 judgement of the ANSI Board of StandardsReview, substantial agreement has been reache

4、d by directly and materially affectedinterests. Substantial agreement means much more than a simple majority, but not nec-essarily 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 Standa
