6、on the Use of American Welding Society StandardsAll standards (codes, specifications, recommended practices, methods, classifications, and guides) of the AmericanWelding Society (AWS) are voluntary consensus standards that have been developed in accordance with the rules of theAmerican National Stan
7、dards Institute (ANSI). When AWS American National Standards are either incorporated in, ormade part of, documents that are included 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 cas
8、es, any changes in those AWSstandards must be approved by the governmental body having statutory jurisdiction before they can become 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. Wher
9、e this contractual relationship exists, changes in or deviations from requirementsof an AWS standard must be by agreement between the contracting parties.AWS American National Standards are developed through a consensus standards development process that bringstogether volunteers representing varied
10、 viewpoints and interests to achieve consensus. While AWS administers the processand establishes rules to promote fairness in the development of consensus, it does not independently test, evaluate, orverify the accuracy of any information or the soundness of any judgments contained in its standards.
11、AWS disclaims liability for any injury to persons or to property, or other damages of any nature whatsoever, whetherspecial, indirect, consequential or compensatory, directly or indirectly resulting from the publication, use of, or relianceon this standard. AWS also makes no guaranty or warranty as
12、to the accuracy or completeness of any informationpublished herein.In issuing and making this standard available, AWS is not undertaking to render professional or other services for or onbehalf of any person or entity. Nor is AWS undertaking to perform any duty owed by any person or entity to someon
13、eelse. Anyone using these documents should rely on his or her own independent judgment or, as appropriate, seek theadvice of a competent professional in determining the exercise of reasonable care in any given circumstances.This standard may be superseded by the issuance of new editions. Users shoul
14、d ensure that they have the latest edition.Publication of this standard does not authorize infringement of any patent or trade name. Users of this standard acceptany and all liabilities for infringement of any patent or trade name items. AWS disclaims liability for the infringement ofany patent or p
15、roduct trade name resulting from the use of this standard.Finally, AWS does not monitor, police, or enforce compliance with this standard, nor does it have the power to do so.On occasion, text, tables, or figures are printed incorrectly, constituting errata. Such errata, when discovered, are postedo
16、n the AWS web page (www.aws.org).Official interpretations of any of the technical requirements of this standard may only be obtained by sending a request,in writing, to the Managing Director, Technical Services Division, American Welding Society, 550 N.W. LeJeune Road,Miami, FL 33126 (see Annex H).
17、With regard to technical inquiries made concerning AWS standards, oral opinionson AWS standards may be rendered. However, such opinions represent only the personal opinions of the particularindividuals giving them. These individuals do not speak on behalf of AWS, nor do these oral opinions constitut
18、e officialor unofficial opinions or interpretations of AWS. In addition, oral opinions are informal and should not be used as asubstitute for an official interpretation.This standard is subject to revision at any time by the AWS D8 Committee on Automotive Welding. It must be reviewedevery five years
19、, and if not revised, it must be either reaffirmed or withdrawn. Comments (recommendations, additions,or deletions) and any pertinent data that may be of use in improving this standard are required and should be addressedto AWS Headquarters. Such comments will receive careful consideration by the AW
20、S D8 Committee on AutomotiveWelding and the author of the comments will be informed of the Committees response to the comments. Guests areinvited to attend all meetings of the AWS D8 Committee on Automotive Welding to express their comments verbally.Procedures for appeal of an adverse decision conce
21、rning all such comments are provided in the Rules of Operation ofthe Technical Activities Committee. A copy of these Rules can be obtained from the American Welding Society, 550N.W.
