硫化橡胶或热塑性橡胶 使用改进的兰伯恩试验机测定耐磨性

[中文适用范围]： 本文件规定了一种使用改进型兰伯恩试验机测定橡胶耐磨性的方法。测定由圆盘状橡胶试件和磨轮之间的圆周速度差引起的滑移所造成的磨损损失，圆盘状橡胶试件和磨轮在特定载荷下独立旋转，其圆周相互挤压，该滑移由圆周速度差引起。试验结果可以报告为单位磨损试验时间或运行距离的体积损失，和/或与参考化合物相比的耐磨性指数。由于改进型兰伯恩试验机能够独立设定各种磨损条件，例如滑移率、滑动速度和载荷，该方法适用于在各种严酷条件下评估一系列橡胶产品（尤其是轮胎）的化合物。附件 A 中给出了轮胎胎面橡胶的测试示例。 [外文原描述]： This document specifies a method for the determination of the resistance of rubber to abrasion using the Improved Lambourn test machine. The abrasion loss resulting from the slip caused by the difference in circumferential speed between a disc-shaped rubber test piece and an abrasive wheel, which are driven to rotate independently with their circumferences pressed against each other by a specified load, is determined. The test result can be reported as a volume loss per abrasion test time or running distance, and/or as an abrasion resistance index compared with a reference compound. As the Improved Lambourn test machine is capable of setting various abrasive conditions, such as slip rate, sliding speed and load, independently, this method is suitable for the evaluation of compounds for a range of rubber products, especially tyres, under a wide range of severity conditions. An example of the testing of tyre tread rubber is given in Annex A.
