1.1 This specification covers the materials, properties, and packaging of dry, combined materials for use as surface bonding mortar with concrete masonry units that have not been prefaced, coated, or painted. 1.2 This specification does not cover design or application. Consult the manufacturer for specific recommendations. 1.3 Appendix X1 of this specification contains the recommended tests for evaluation of surface bonded masonry assemblages used to establish design loads for the composite wall. 1.4 Appendix X2 through Appendix X5 of this specification contain additional tests that may be performed on surface bonding mortar. 1.5 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. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 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. |
