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 (Specifications C55 , C73 , C1634 ) Annex A3 —Segmental retaining wall units (Specification C1372 ) Annex A4 —Concrete interlocking paving units (Specification C936/C936M ) Annex A5 —Concrete grid paving units (Specification C1319 ) Annex A6 —Manufactured concrete ballast units (Specification C1884 ) Annex A7 —Dry-cast articulating concrete block (Specification D6684 ) Annex A8 —Segmental and pedestal-set concrete paving slabs (Specification C1782/C1782M and C1944/C1944M ) 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: Section Scope 1 Referenced Documents 2 Terminology 3 Significance and Use 4 Sampling 5 Measurement of Dimensions 6 Compressive Strength 7 Absorption 8 Calculations 9 Report 10 Keywords 11 Annexes—Test Procedures Concrete Masonry Units Annex A1 Concrete and Calcium Silicate Brick Annex A2 Segmental Retaining Wall Units Annex A3 Concrete Interlocking Paving Units Annex A4 Concrete Grid Paving Units Annex A5 Manufactured Concrete Ballast Units Annex A6 Dry-Cast Articulating Concrete Block Annex A7 Segmental and Pedestal-Set Concrete Paving Slabs Annex A8 Worksheet and Test Report for Concrete Masonry Units Appendix X1 Test Report for Concrete Interlocking Paving Units Appendix X2 Calculation of Normalized Web Area Appendix X3 Note 1: The testing laboratory performing these test methods should be evaluated in accordance with Practice C1093 . 1.5 The text of this test method references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.7 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== 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. 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. 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.
