Significance and Use
4.1 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.
4.2 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.
Scope
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 A1—Concrete masonry units (Specifications C90, C129) |
| Annex A2—Concrete and calcium silicate brick |
| Annex A3—Segmental retaining wall units (Specification C1372) |
| Annex A4—Concrete interlocking paving units |
| Annex A7—Dry-cast articulating concrete block |
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.
1.4 These test methods include the following sections:

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.
