8、 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 Standards Institute (ANSI). When AWS standards are either incorporated in, or made part o

9、f,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 beapproved by the governmental body having statutory jurisdic

10、tion before they can become a part of those laws andregulations. In all cases, these standards carry the full legal authority of the contract or other document that invokes theAWS standards. Where this contractual relationship exists, changes in or deviations from requirements of an AWSstandard must

11、 be by agreement between the contracting parties.AWS American National Standards are developed through a consensus standards development process that bringstogether volunteers representing varied viewpoints and interests to achieve consensus. While AWS administers the processand establishes rules to

12、 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.AWS disclaims liability for any injury to persons or to property, or other damages of any nature whatsoev

13、er, 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 to the accuracy or completeness of any informationpublished herein.In issuing and making this standard av

14、ailable, 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 someoneelse. Anyone using these documents should rely on his or her own independent judgment or, as appropriate

15、, 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a competent professional in determining the exercise of reasonable care in any given circumstances.This standard may be superseded by the issuance of new editions.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 should ensure that they have the latest edition.Publication of this standard does not authorize infringement o

16、f 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 product trade name resulting from the use of this standard.Finally, AWS does not monitor, police, or enfor

17、ce 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 postedon the AWS web page (www.aws.org).Official interpretations of any of the technical requirements of this st

18、andard 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. With regard to technical inquiries made concerning AWS standards, oral opinions on AWS standardsmay be rendered. Howeve

19、r, such opinions represent only the personal opinions of the particular individuals giving them.These individuals do not speak on behalf of AWS, nor do these oral opinions constitute official or unofficial opinions orinterpretations of AWS. In addition, oral opinions are informal and should not be u

20、sed as a substitute for an officialinterpretation.This standard is subject to revision at any time by the AWS A5 Committee on Filler Metal. It must be reviewed everyfive years, and if not revised, it must be either reaffirmed or withdrawn. Comments (recommendations, additions, ordeletions) and any p

21、ertinent data that may be of use in improving this standard are required and should be addressed toAWS Headquarters. Such comments will receive careful consideration by the AWS A5 Committee on Filler Metal andthe author of the comments will be informed of the Committees response to the comments. Gue

22、sts are invited to attendall meetings of the AWS A5 Committee on Filler Metal to express their comments verbally. Procedures for appeal ofan adverse decision concerning all such comments are provided in the Rules of Operation of the Technical ActivitiesCommittee. A copy of these Rules can be obtaine
