Standard Test Method for Obtaining and Testing Drilled Cores and Sawed Beams ofConcrete

Standard Test Method for Obtaining and Testing Drilled Cores and Sawed Beams ofConcrete1 1. Scope* 1.1 This test method covers obtaining, preparing, and test- ing cores drilled from concrete for length or compressivestrength or splitting tensile strength determinations.This test method is not applicable to cores from shotcrete. NoE 1—Test Method C1604/C1604M is applicable for obtaining,preparing,and testing cores from shotcrete. NoTE 2—Appendix X1 provides recommendations for obtaining andtesting sawed beams for flexural performance. 1.2 The values stated in either Sl units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore，cachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard. 1.3 The text of this standard references notes and footnotesthat provide explanatory material. These notes and footnotes(excluding those in tables and figures) shall not be consideredas requirements of the standard. 1.4 This standard does nor purport to address the safetyconcerns.if cany; associated with its se.It is the responsibiliryof the user of this standard to establish appropriate safety andhealth pracrices and determine the applicability of regulatorylimitations prior to use. 2.
