1、Designation:C500/C500M07(Reapproved 2011)1Standard Test Methods forAsbestos-Cement Pipe1This standard is issued under the fixed designation C500/C500M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number
2、 in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1NOTEUnits information was editorially corrected in January 2012.1.Scope1.1 These test methods cover the testing of asbestos-cementpipe for hydrostatic str
