1、Designation:C1587/C1587M15Standard Practice forPreparation of Field Removed Manufactured Masonry Unitsand Masonry Specimens for Testing1This standard is issued under the fixed designation C1587/C1587M;the number immediately following the designation indicates theyear of original adoption or,in the c
2、ase of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 The purpose of this practice is to standardize thepreparation of manufactured masonry units an
3、d masonry speci-mens extracted from the field for compressive and flexuralbond strength testing in a laboratory environment.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The inch-pound unitsare shown in brackets.The values stated in each system
4、 maynot be exact equivalents;therefore,each system shall be usedindependently of the other.Combining values from the twosystems may result in non-conformance with the standard.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibili
