1.1 这些试验方法包括测定砌体墙构件强度和荷载-挠度特性的方法。 1.2 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本标准中描述的测试方法旨在作为制定砌体构件特定测试协议的起点。 4.1.1 测试协议可用于砌体构件荷载-挠度行为的一般研究。 4.1.2 测试协议可用于评估服务机构和其他方鉴定砌体构件和材料。 4.1.3 本标准中描述的试验方法是通用的，旨在适用于解决广泛的预期支撑和负载条件。 4.2 如何解释测试结果将取决于被测试砌体构件的预期用途。

1.1 These test methods cover methods for determining the strength and load-deflection characteristics of masonry wall elements. 1.2 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. 1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 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. ====== Significance And Use ====== 4.1 The test methods described in this standard are intended for use as a starting point in developing specific testing protocols for masonry elements. 4.1.1 The testing protocols could be used for general research on the load-deflection behavior of masonry elements. 4.1.2 The testing protocols could be used for qualification of masonry elements and materials by evaluation services and other parties. 4.1.3 The test methods described in this standard are general, and are intended to be adaptable to address a wide range of anticipated support and loading conditions. 4.2 How the test results are interpreted will depend on the intended use of the masonry element being tested.
