1.1 本试验方法涵盖了确定承受静载荷时钉子弯曲屈服力矩的程序。它仅适用于工程连接应用中使用的钉子，其中所需的连接容量由设计师指定。 1.2 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 注1: 本试验方法适用于任何英寸磅 F1575 或国际单位制[ F1575M ]. SI中的值是两个有效数字的数学转换，并显示在括号中[ ]. 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====== 5.1 钉子是木结构中常见的机械紧固件。目前，用于确定横向加载钉连接能力的工程设计程序使用屈服理论来确定所设计的横向加载钉连接的标称阻力。为了确定侧向荷载钉连接的标称阻力，必须知道弯曲屈服力矩。

1.1 This test method covers procedures for determining the bending yield moment of nails when subjected to static loading. It is intended only for nails used in engineered connection applications, in which a required connection capacity is specified by the designer. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. Note 1: This test method is applicable in either inch-pounds F1575 or SI Units [ F1575M ]. Values stated in SI are a mathematical conversion of two significant digits and are shown in brackets [ ]. 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 ====== 5.1 Nails are a common mechanical fastener in wood structures. Engineering design procedures used to determine the capacities of laterally-loaded nailed connections currently use a yield theory to establish the nominal resistance for laterally-loaded nailed connections that are engineered. In order to develop the nominal resistance for laterally-loaded nailed connections, the bending yield moment must be known.
