13、eveloped in accordance with the rules of theAmerican National Standards Institute (ANSI). 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 fu
14、ll legal authority of the statute. In such cases, any changes in those AWS standards must beapproved by the governmental body having statutory jurisdiction before they can become a part of those laws andregulations. In all cases, these standards carry the full legal authority of the contract or othe
15、r document that invokes theAWS standards. Where this contractual relationship exists, changes in or deviations from requirements of an AWSstandard must be by agreement between the contracting parties.International Standard Book Number: 0-87171-430-2American Welding Society, 550 N.W.
