7、S D15.2/D15.2M:2013iiiStatement 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 ru

8、les 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 state laws and regulations, or the regulations of other governmen-tal bodies, their provisions carry the full legal autho

9、rity of the statute. In such cases, any changes in those AWS standardsmust be approved by the governmental body having statutory jurisdiction 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 tha

10、t invokes theAWS standards. Where this contractual relationship exists, changes in or deviations from requirements of an AWS stan-dard must be by agreement between the contracting parties.AWS American National Standards are developed through a consensus standards development process that bringstoget

11、her volunteers representing varied viewpoints and interests to achieve consensus. While AWS administers theprocess and establishes rules to promote 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 j

12、udgments contained in its standards.AWS disclaims liability for any injury to persons or to property, or other damages of any nature whatsoever, whether spe-cial, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, or reliance onthis standard.

18、he power to do so.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. Such requests should be addressed to the American Welding Society,Attention: Managing Director, Technical Ser

19、vices Division, 8669 Doral Blvd., Suite 130, Doral, FL 33166 (see AnnexF). With regard to technical inquiries made concerning AWS standards, oral opinions on AWS standards may be ren-dered.

These individualsdo not speak on behalf of AWS, nor do these oral opinions constitute official or unofficial opinions or interpretations ofAWS. In addition, oral opinions are informal and sho

21、uld 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. Comments (recommendations, additions,or de

22、letions) 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 be informed of the Committees respon

23、se to the comments. Guests areinvited to attend all meetings of the AWS D15 Committee on Railroad Welding to express their comments verbally.Procedures for appeal of an adverse decision concerning all such comments are provided in the Rules of Operation of theTechnical Activities Committee.
