8、s, and guides) 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

9、 in federal or state laws and regulations, or the regulations of other govern-mental bodies, their provisions carry the full legal authority of the statute. In such cases, any changes in those AWSstandards must be approved by the governmental body having statutory jurisdiction before they can become

10、 a part ofthose laws and regulations. In all cases, these standards carry the full legal authority of the contract or other documentthat invokes the AWS standards. Where this contractual relationship exists, changes in or deviations from requirementsof an AWS standard must be by agreement between th

46、1. IntroductionThe American Welding Society (AWS) Board of Direc-tors has adopted a policy whereby all official interpreta-tions of AWS standards are handled in a formal manner.Under this policy, all interpretations are made by thecommittee that is responsible for the standard. Officialcommunication

47、 concerning an interpretation is directedthrough the AWS staff member who works with thatcommittee. The policy requires that all requests for aninterpretation be submitted in writing. Such requests willbe handled as expeditiously as possible, but due to thecomplexity of the work and the procedures t

48、hat must befollowed, some interpretations may require considerabletime.A2. ProcedureAll inquiries shall be directed to:Managing DirectorTechnical Services DivisionAmerican Welding Society8669 Doral Blvd., Suite 130Doral, FL 33166All inquiries shall contain the name, address, and affilia-tion of the

49、inquirer, and they shall provide enough infor-mation for the committee to understand the point ofconcern in the inquiry. When the point is not clearlydefined, the inquiry will be returned for clarification. Forefficient handling, all inquiries should be typewritten andin the format specified below.A2.1 Scope. Each inquiry shall address one single provi-sion of th
