Standard Method of Test for
Obtaining and Testing Drilled Cores
and Sawed Beams of Concrete
AASHTO Designation:T 24M/T 24-07
ASTM Designation:C 42/C 42M-04
1.1.This method covers obtaining, preparing, and testing (l} cores drilled from concrete for length or compressive or
splitting tensile strength determinations; and (2) beams sawed from concrete for flexural strength determinations.
1.2.The values stated in SI units or inch-pound units are to be regarded separately as the standard.
Within the text, the inch-pound units are shown in brackets. The values stated in each system are
not exact equivalents; therefore, each system shall be used independently of the other.
Combining values from the two systems may result in nonconformance with the standard.
