(Test Method)Standard Test Methods for Sampling and Testing Concrete Masonry Units and Related Units
Standard Test Methods for Sampling and Testing Concrete Masonry Units and Related Units
SCOPE
1.1 These test methods cover the sampling and testing of concrete masonry units for dimensions, compressive strength, absorption, unit weight (density), and moisture content. Flexural load testing and ballast weight determination of concrete roof pavers are also covered. Note 1 - The testing laboratory performing these test methods should be evaluated in accordance with Practice C 1093.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
