ASTM C1314-02

Standard Test Method for Compressive Strength of Masonry Prisms

SCOPE
1.1 This test method covers procedures for masonry prism construction and testing, and procedures for determining the compressive strength of masonry, f'mt', used to determine compliance with the specified compressive strength of masonry,  f `m'. When this test method is used for research purposes, the construction and test procedures within serve as a guideline and provide control parameters.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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.
