1.1 本试验方法涵盖金属材料的销式轴承试验，以确定轴承屈服强度和轴承强度。 注1: 轴承表面附带润滑剂的存在可能会显著降低通过该方法获得的轴承屈服强度值。 1.2 单位- 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和健康实践，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 从轴承试验中获得的数据是轴承极限强度和屈服强度。这些数据提供了通过距离试样边缘特定距离的孔，用紧密配合的圆柱销加载的材料边缘承载能力的测量值。 4.2 在销不受限制的情况下，轴承特性在材料比较和结构设计中很有用。

1.1 This test method covers a pin-type bearing test of metallic materials to determine bearing yield strength and bearing strength. Note 1: The presence of incidental lubricants on the bearing surfaces may significantly lower the value of bearing yield strength obtained by this method. 1.2 Units— 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 and health 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 data obtained from the bearing test are the bearing ultimate and yield strength. The data provide a measure of the load-carrying capacity of a material edge loaded with a close-fitting cylindrical pin through a hole located a specific distance from the specimen edge. 4.2 Bearing properties are useful in the comparison of materials and design of structures under conditions where the pin is not restricted.
