1.1本试验方法涵盖了使用英国摆锤抗滑测试仪测量表面摩擦特性的程序。附录中包含了测试仪的校准方法。 1.2英国摆锤测试仪是一种动态摆锤冲击式测试仪，用于测量将橡胶滑块边缘推过测试表面时的能量损失。该测试仪适用于平坦表面上的实验室和现场测试，以及从加速抛光轮测试中测量弯曲实验室试样的抛光值。 1.3测量值，BPN=平面的英国摆锤（测试仪）数和加速抛光的抛光值- 车轮试样代表使用仪器和本文所述程序获得的摩擦特性，不一定与其他滑动度测量设备一致或相关。 1.4 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。 1.5以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 ====意义和用途====== 本试验方法在现场或实验室中测量表面的摩擦性能、微观结构。 本试验方法可用于确定各种抛光工艺对材料或材料组合的相对影响。 根据该方法测量的值不一定与使用其他方法确定摩擦性能或防滑性获得的值一致或直接相关。 笔记 类似类型表面的1-BPN和抛光值在数值上不相等，主要是因为滑动长度和表面形状不同。 不建议通过数学操作或使用特殊测量尺度对抛光值进行理论校正，以获得数值相等性。

1.1 This test method covers the procedure for measuring surface frictional properties using the British Pendulum Skid Resistance Tester. A method for calibration of the tester is included in the Annex. 1.2 The British Pendulum Tester is a dynamic pendulum impact-type tester used to measure the energy loss when a rubber slider edge is propelled over a test surface. The tester is suited for laboratory as well as field tests on flat surfaces, and for polish value measurements on curved laboratory specimens from accelerated polishing-wheel tests. 1.3 The values measured, BPN = British Pendulum (Tester) Number for flat surfaces and polish values for accelerated polishing-wheel specimens, represent the frictional properties obtained with the apparatus and the procedures stated herein and do not necessarily agree or correlate with other slipperiness measuring equipment. 1.4 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. 1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. ====== Significance And Use ====== This test method provides a measure of a frictional property, microtexture, of surfaces, either in the field or in the laboratory. This test method may be used to determine the relative effects of various polishing processes on materials or material combinations. The values measured in accordance with this method do not necessarily agree or directly correlate with those obtained utilizing other methods of determining friction properties or skid resistance. Note 1—BPN and polish values from similar types of surfaces will not be numerically equal, primarily because of the differences in slide length and surface shape. Theoretical correction of the polish values to obtain numerical equality, either by mathematical manipulation or by use of special measuring scales is not recommended.
