1.1 本规程涵盖了确定磨损量W的程序 五、 使用SRV试验机，通过触针尖端轮廓术，在高频线性振荡运动下，对试件上的磨损痕和轨迹进行摩擦学应力测量。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 本标准并不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建立适当的安全、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 在摩擦学测试中，磨损量的确定成为一个关键因素，因为它比磨痕直径更具辨别力，因为光学可见的磨痕直径可能表明或可能不表明球表面和磨损轨迹上的磨损是材料的不可逆损失。 此测试方法的用户应确定结果是否与现场性能或其他应用相关。 注3: 据信，触觉触针尖端轮廓仪确定了最真实的图形，并且比在非接触模式下操作的光学轮廓仪更频繁地使用。

1.1 This practice covers a procedure for determining the wear volume W V of wear scars and tracks on test pieces tribologically stresses under high-frequency, linear-oscillation motion using a SRV test machine by means of stylus tip profilometry. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 ====== 5.1 The determination of the wear volume becomes in tribological testing a key element, as it is more discriminative than the wear scar diameter, because an optically visible wear scar diameter may or may not indicate wear on the surface of the ball and the wear track as an irreversible loss of material. Users of this test method should determine whether results correlate with field performance or other applications. Note 3: It is believed, that tactile stylus tip profilometer determines the most realistic figure and are more frequent in use, than it can be achieved by optical profilometers operating in a non-contacting mode.
