Significance and Use

These test methods provide general testing requirements for application to a broad range of concrete products. Those general testing requirements are included in the body of this standard.

Note 2—Consult manufacturer, supplier, product specifications, or other resources for more specific measurement or testing guidelines for those products not addressed with the annex of this standard.

These test methods provide specific testing requirements in two distinct sections, the requirements applicable to all units covered by these test methods and those applicable to the specific unit types. The requirements applicable to all units are included in the body of these test methods and those applicable to the specific unit types are included within the annexes.


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:

Annex A1Concrete masonry units (Specifications C90, C129)
Annex A2Concrete and calcium silicate brick
(Specifications C55, C73, C1634)
Annex A3Segmental retaining wall units (Specification C1372)
Annex A4Concrete interlocking paving units
(Specification C936/C936M)
Annex A5Concrete grid paving units (Specification C1319)
Annex A6Concrete roof pavers (Specification C1491)
Annex A7Dry-cast articulating concrete block
(Specification D6684)

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.

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.
