19、of the AmericanWelding Society (AWS) are voluntary consensus standards that have been developed in accordance with the rules of theAmerican National Standards Institute (ANSI). When AWS American National Standards are either incorporated in, ormade part of, documents that are included in federal or
20、state laws and regulations, or the regulations of other governmen-tal bodies, their provisions carry the full legal authority of the statute.
