1.1 本试验方法提供了测定单个砌体拉杆和锚栓抵抗砌体砂浆接缝拔出的能力的程序。 1.2 提供了两种实验室测试程序，用于测试样本，其中包括嵌入双叠砌合砌体单元之间砂浆中的砌体拉杆或锚。 1.2.1 程序A- 适用于小型（砖尺寸）砌块。 1.2.2 程序B- 用于大型（砌块尺寸）砌块。 1.3 以英寸-磅单位表示的数值视为标准值。括号中给出的值是数学转换为SI单位，仅供参考，不被视为标准单位。 1.4 本标准并不旨在解决与其使用相关的安全问题（如有）。本标准的使用者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。 1.5 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====== 5.1 本试验方法旨在提供一种简单、廉价的方法，以生成与不同类型砌体单元和砂浆一起使用的各种拉杆和锚栓的拉拔强度的保守比较数据。建议使用此试验方法，直到可以开发出经济、改进的方法来更全面地模拟使用条件。

1.1 This test method provides procedures for determining the ability of individual masonry ties and anchors to resist extraction from a masonry mortar joint. 1.2 Two laboratory testing procedures are provided for use with test specimens which consist of a masonry tie or anchor embedded in mortar between twin stack-bonded masonry units. 1.2.1 Procedure A— For use with small (brick-size) masonry units. 1.2.2 Procedure B— For use with large (block-size) masonry units. 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. 1.4 This standard does not purport to address 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. 1.5 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 ====== 5.1 This test method is intended to provide a simple inexpensive means of generating conservative, comparative data on pullout strengths of various ties and anchors used with different types of masonry units and mortars. This test method is recommended for such use until economical, improved methods can be developed to simulate service conditions more inclusively.
