7、thods, 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 American National Standards are either incorporated in, ormade part of, docume
8、nts 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 cases, any changes in those AWSstandards must be approved by the governmental body having statutory jurisdiction b
9、efore 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. Where this contractual relationship exists, changes in or deviations from requirementsof an AWS standard must be by
10、 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 the AWS administers theprocess and establishes rules to p
11、romote fairness in the development of consensus, it does not independently test, evalu-ate, or verify 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

AWS also makes no guarantee or warranty as to the accuracy or completeness of any informationpublished herein.In issuing and making this standard
13、available, AWS is neither undertaking to render professional or other services for oron behalf 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 appro
14、priate, seek theadvice of a competent professional in determining the exercise of reasonable care in any given circumstances. It isassumed that the use of this standard and its provisions is entrusted to appropriately qualified and competent personnel.This standard may be superseded by the issuance
15、of new editions. This standard may also be corrected through publicationof amendments or errata. It may also be supplemented by publication of addenda. Information on the latest editions ofAWS standards including amendments, errata, and addenda are posted on the AWS web page (www.aws.org). Users sho

Users of this standard acceptany and all liabilities for infringement of any patent or trade name items. AWS disclaims liability for
17、the infringement ofany patent or product trade name resulting from the use of this standard.The 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,
18、 when discovered, are postedon 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 appropriate technical committee.

19、,Attention: Managing Director, Technical Services Division, 8669 NW 36 St, # 130, Miami, FL 33166 (see Annex G).With regard to technical inquiries made concerning AWS standards, oral opinions on AWS standards may be rendered.These opinions are offered solely as a convenience to users of this standar
20、d, and they do not constitute professional ad-vice. Such opinions represent only the personal opinions of the particular individuals giving them. These individuals donot speak on behalf of AWS, nor do these oral opinions constitute official or unofficial opinions or interpretations ofAWS. In additio
21、n, oral opinions are informal and should not be used as a substitute for an official interpretation.This standard is subject to revision at any time by the AWS D15 Committee on Railroad Welding. It must be reviewedevery five years, and if not revised, it must be either reaffirmed or withdrawn. Comme
22、nts (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 AWS D15 Committee on RailroadWelding and the author of the comments will
23、 be informed of the Committees response to the comments. Guests are in-vited to attend all meetings of the AWS D15 Committee on Railroad Welding to express their comments verbally.
