硫化橡胶或热塑性橡胶 使用旋转圆柱形滚筒装置测定耐磨性

[中文适用范围]： 本文件规定了两种利用旋转圆柱形滚筒装置测定橡胶耐磨性的方法。这两种方法涉及测定由于将试件在规定等级的磨料片上摩擦而引起的体积损失。方法 A 适用于非旋转试件，方法 B 适用于旋转试件。对于每种方法，结果都可以报告为相对体积损失或耐磨性指数。这些测试方法适用于比较测试、质量控制、规范合规性测试、仲裁目的以及研发工作。无法推断出该磨耗试验结果与使用性能之间没有密切关系。注：使用旋转试件时磨损损失通常更均匀，因为试件的整个表面在整个测试期间都与磨料片接触。然而，使用非旋转试件也有相当多的经验。 [外文原描述]： This document specifies two methods for the determination of the resistance of rubber to abrasion by means of a rotating cylindrical drum device. The methods involve determination of the volume loss due to the abrasive action of rubbing a test piece over a specified grade of abrasive sheet. Method A is for a non-rotating test piece and method B is for a rotating test piece. For each method, the result can be reported as a relative volume loss or an abrasion resistance index. These test methods are suitable for comparative testing, quality control, specification compliance testing, referee purposes and research and development work. No close relation between the results of this abrasion test and service performance can be inferred. NOTE The abrasion loss is often more uniform using the rotating test piece because the whole surface of the test piece is in contact with the abrasive sheet over the duration of the test. However, there is considerable experience using the non-rotating test piece.
