34、nsensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been rached by directly and materially affected interests. Substantial agreement means much more than a s
35、imple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. AMERICAN NATIONAL STANDARD The use of American NationaI Standards is completely voluntary; their existence does not i n any resp
36、ect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpr
37、etation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard i n the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose
38、 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 CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time.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 require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers
39、of American National Standards may receive current information on all standards by calling or writing the American National Standards Institute.
