All standards (codes, specifications, recommnended practices, methods, lassifications, and guides) of the American Welding Society are voluntary consensus standards that have been developed in accordance with the rules of the American National Standards Institute. When AWS standards are either incorporated in, or made part of, documents that are included in federal or state laws and regultions, or the regulations of other governmental bodies, their provi-sions carry the full legal authority of the statute. In such cases, any 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 this contractual relationship exists, changes in or deviations from requiremnents of an AWS standard must be by agreement between the contracting parties.
