IntroductionThe American Welding Society (AWS) Board of Directorshas adopted a policy whereby all officia
40、l interpretations ofAWS standards are handled in a formal manner. Under thispolicy, all interpretations are made by the committee that isresponsible for the standard. Official communication con-cerning an interpretation is directed through the AWS staffmember who works with that committee. The polic
41、yrequires that all requests for an interpretation be submittedin writing. Such requests will be handled as expeditiouslyas possible, but due to the complexity of the work and theprocedures that must be followed, some interpretationsmay require considerable time.A2. ProcedureAll inquiries shall be di
42、rected to:Managing DirectorTechnical Services DivisionAmerican Welding Society550 N.W. LeJeune RoadMiami, FL 33126All inquiries shall contain the name, address, and affilia-tion of the inquirer, and they shall provide enough infor-mation for the committee to understand the point ofconcern in the inq
43、uiry. 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 singleprovision of the standard unless the point of the inquiryinvolves t
44、wo or more interrelated provisions. Theprovision(s) shall be identified in the scope of the inquiryalong with the edition of the standard that contains theprovision(s) the inquirer is addressing.A2.2 Purpose of the Inquiry. The purpose of the inquiryshall be stated in this portion of the inquiry. Th
45、e purposecan be to obtain an interpretation of a standardsrequirement or to request the revision of a particularprovision in the standard.A2.3 Content of the Inquiry. The inquiry should beconcise, yet complete, to enable the committee tounderstand the point of the inquiry. Sketches should beused whe
46、never appropriate, and all paragraphs, figures,and tables (or annex) that bear on the inquiry shall becited. If the point of the inquiry is to obtain a revision ofthe standard, the inquiry shall provide technicaljustification for that revision.A2.4 Proposed Reply. The inquirer should, as aproposed r
47、eply, state an interpretation of the provisionthat is the point of the inquiry or provide the wording fora proposed revision, if this is what the inquirer seeks.A3. Interpretation of Provisions ofthe StandardInterpretations of provisions of the standard are made bythe relevant AWS technical committe
48、e. The secretary ofthe committee refers all inquiries to the chair of the partic-ular subcommittee that has jurisdiction over the portion ofthe standard addressed by the inquiry. The subcommitteereviews the inquiry and the proposed reply to determineStandard Welding Procedure Specification (SWPS)wha
49、t the response to the inquiry should be. Following thesubcommittees development of the response, the inquiryand the response are presented to the entire committee forreview and approval. Upon approval by the committee, theinterpretation is an official interpretation of the Society,and the secretary transmits the response to the inqui
