标准范围

本文件规定了使用改进的Lambourn试验机测定橡胶耐磨性的方法。测定由圆盘状橡胶试验片和砂轮之间的圆周速度差引起的滑动引起的磨损损失，所述圆盘状橡胶试验片和砂轮通过规定的载荷相互按压而独立旋转。测试结果可以报告为每磨损测试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。由于改进的Lambourn试验机能够独立地设置各种磨料条件，例如滑移率、滑动速度和载荷，因此该方法适用于在广泛的严重程度条件下评估一系列橡胶产品，特别是轮胎的化合物。轮胎胎面橡胶的试验实例见附录？A.

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.
