Standard Specification for Adhered Concrete Masonry Units

SCOPE
1.1 This specification covers solid, dry-cast, concrete masonry units intended for use as an interior and exterior adhered veneer and are made from portland cement, water, and suitable mineral aggregates with or without the inclusion of other materials.  
1.2 The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
Note 1: Adhered concrete masonry units covered by this specification are made from lightweight or normal weight aggregates, or both.
Note 2: When particular features are desired, such as density classification, surface textures for appearance or bond, finish, color, fire resistance, insulation, acoustical properties, or other special features, such properties should be specified separately by the purchaser. Suppliers should be consulted as to the availability of adhered concrete masonry units having the desired features.  
1.4 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.
