1.1 These test methods provide various testing procedures commonly used for evaluating characteristics of concrete masonry units and related concrete units. Methods are provided for sampling, measurement of dimensions, compressive strength, absorption, unit weight (density), moisture content, flexural load, and ballast weight. Not all methods are applicable to all unit types, however.
1.2 Specific testing and reporting procedures are included in annexes to these test methods for the following specific unit types:
(Specifications C55, C73, C1634)
1.3 The test procedures included in these test methods are also applicable to other types of units not referenced in these test methods, but specific testing and reporting requirements for those units are not included.

Concrete Masonry Units
Note 1—The testing laboratory performing these test methods should be evaluated in accordance with Practice C1093.
1.5 The values stated in inch-pound units are to be regarded as the standard, except in Annex A4, where either SI units or inch-pound units are to be regarded separately as standard. The values given in parentheses throughout are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.6 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.
