AMERICAN NATIONAL STANDARDS
By approving this American National Standard, the ANSI Board of Standards Review confirms that the requirements for
due process, consensus, balance and openness have been met by B11 Standards, Inc., (the ANSI-accredited standards
developing organization). American National Standards are developed through a consensus process. Consensus is
established when substantial agreement has been reached by directly and materially affected interests. Substantial
agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views
and objections be considered, and that a concerted effort be made toward resolution. This process brings together
volunteers and/or seeks out the views of persons who have an interest in the topic covered by this publication. While B11
Standards, Inc., administers the process and establishes procedures to promote fairness in the development of consensus,
it does not write the document and it does not independently test, evaluate or verify the accuracy or completeness of any
information or the soundness of any judgments contained in its standards or guidelines.
American National Standards are promulgated through ANSI for voluntary use; their existence does not in any respect
preclude anyone, whether they have approved the standards or not, from manufacturing, marketing, purchasing, or using
products, processes, or procedures not conforming to the standards. However, users, distributors, regulatory bodies,
certification agencies and others concerned may apply American National Standards as mandatory requirements in
commerce and industry.
Neither B11 Standards, Inc. nor any of the organizations or individuals that assisted in authoring, developing,
editing or distributing this standard (B11 Standards, Inc. and such organizations and individuals collectively
