1.1 本规范涵盖了用于修复砌体的砂浆，其建造方法和材料早于现行建筑标准的制定。砂浆可用于非结构性目的，如砌体的重新定位，或用于结构性目的，例如但不限于重建或修复有助于砌体结构完整性的砂浆接缝。 1.2 砌体包括以下用砂浆铺设的单元:( 1. )铸石( 2. )粘土砖和瓷砖( 3. )混凝土砌体( 4. )天然石材( 5. )赤陶，以及( 6. )硅酸钙。 1.3 本规范可用于对项目的砂浆进行资格预审。 1.4 使用本规范测试的砂浆是实验室制备的砂浆，并不代表现场砂浆。 1.5 本规范为根据性能、材料和美学要求设计合适的砂浆配方提供了依据。 使用本规范需要彻底了解砌体组件在组件结构、水管理和长期性能方面的保护和持续性能的功能、维护和维修要求。 1.6 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对国际单位制的数学转换，仅供参考，不被视为标准值。 1.7 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification covers mortar for the repair of masonry constructed with methods and materials that pre-date the origination of current standards of construction. The mortar may be used for non-structural purposes such as repointing of the masonry, or for structural purposes such as, but not restricted to, re-construction or repair of mortar joints that contribute to the structural integrity of the masonry. 1.2 Masonry includes the following units laid in mortar: ( 1 ) cast stone, ( 2 ) clay brick and tile, ( 3 ) concrete masonry, ( 4 ) natural stone, ( 5 ) terra cotta, and ( 6 ) calcium silicate. 1.3 This specification may be used to pre-qualify mortar for a project. 1.4 Mortars tested using this specification are laboratory-prepared mortars and do not represent in-place, site mortars. 1.5 This specification provides a basis for the design of an appropriate mortar formulation based upon performance, material and aesthetic requirements. Use of this specification requires a thorough understanding of the function, maintenance, and repair requirements for the preservation and continued performance of the masonry assembly in the context of the assembly’s structure, water management, and long-term performance. 1.6 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. 1.7 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.
