IntroductionThe American Welding Society (AWS) Board of Directorshas adopted a policy whereby all official interpretations ofAWS standa

47、rds are handled in a formal manner. Under thatpolicy, 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 policyrequires that all requests fo

48、r 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.
