21、of American Welding Society StandardsAll standards (codes, specifications, recommended practices, methods, classifications, and guides) of the American Welding Society (AWS) are voluntary consensus standards that have been developed in accordance with the rules of the American National Standards Ins

22、titute (ANSI). When AWS American National Standards are either incorporated in, or made part of, documents that are included in federal or state laws and regulations, or the regulations of other governmen-tal bodies, their provisions carry the full legal authority of the statute. In such cases, any

23、changes in those AWS standards must be approved by the governmental body having statutory jurisdiction before they can become a part of those laws and regulations. In all cases, these standards carry the full legal authority of the contract or other document that invokes the AWS standards. Where thi

24、s contractual relationship exists, changes in or deviations from requirements of an AWS stand-ard must be by agreement between the contracting parties.AWS American National Standards are developed through a consensus standards development process that brings together volunteers representing varied v

25、iewpoints and interests to achieve consensus. While AWS administers the process and establishes rules to promote fairness in the development of consensus, it does not independently test, evaluate, or verify the accuracy of any information or the soundness of any judgments contained in its standards.

It must be reviewed every five years, and if not revised, it must be either reaffirmed or withdrawn. Comments (recom-mendations, additions, or deletions) and any pertinent data that may be of

36、use in improving this standard are requested and should be addressed to AWS Headquarters. Such comments will receive careful consideration by the AWS B2 Committee on Procedure and Performance Qualification and the author of the comments will be informed of the Committees response to the comments. Gu
