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:
