1.1 本试验方法提供了确定单个砌体拉杆和锚件抵抗从砌体砂浆接缝中拔出的能力的程序。 1.2 提供了两种实验室测试程序，用于测试由嵌入双垛粘结砌块之间砂浆中的砌石拉杆或锚组成的试样。 1.2.1 程序A- 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。 1.4 本标准无意解决与其使用相关的安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====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块和砂浆一起使用的各种拉杆和锚的抗拔强度的保守、比较数据。建议使用该试验方法，直到可以开发出经济、改进的方法，以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 and health practices and determine the applicability of regulatory limitations prior to use. ====== 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.
