ASTM C140-08
Historical Standard: ASTM C140-08 Standard Test Methods for Sampling and Testing Concrete Masonry Units and Related Units
SUPERSEDED (see Active link, below)
1. 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 C 90 , C 129 ) |
| Annex A2 Concrete brick (Specifications C 55 , C 73 , C 1634 ) |
| Annex A3 Segmental retaining wall units (Specification C 1372 ) |
| Annex A4 Concrete interlocking paving units (Specification C 936 ) |
| Annex A5 Concrete grid paving units (Specification C 1319 ) |
| Annex A6 Concrete roof pavers (Specification C 1491 ) |
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.

1.5 The values stated in inch-pound units are to be regarded as the standard, except in Annex A4, where SI units are to be regarded 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.
