4、equirements for due process, consensus, and other criteria for approval have been met by the standards developer. An American National Standard implies a consensus of those substantially concerned with its scope and provisions. Consensus is established when, in the judgment of the ANSI Board of Stan

Consensus requires that all views and objections be considered, and that a concerted effort be made toward
