All standards of the American Welding Society (codes, specifications, recommended practices, methods, etc.) 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 regulations, or the regulations of other governmental bodies, their provisions carry the full
legal authority of the statute. In such cases, any changes in those AWS standards must be approved by the govern-
mental 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 requirements of an AWS standard must be
by agreement between the contracting parties.
