BS ISO 4649:2017规定了两种通过试验测定橡胶耐磨性的方法 旋转圆筒装置的方式。这些方法包括测定因摩擦试样的研磨作用而产生的体积损失 超过规定等级的砂纸。方法A适用于非旋转试样，方法B适用于A 旋转试样。对于每种方法，结果都可以报告为相对体积损失或磨损 阻力指数。这些测试方法适用于比较测试、质量控制和规范合规性 测试、裁判目的和研发工作。研究结果之间没有密切关系 可以推断出磨损试验和使用性能。 注:使用旋转试样时，磨损损失通常更均匀，因为试样的整个表面 在试验期间，试样与砂纸接触。然而，有相当大的风险 有使用非旋转试件的经验。交叉引用:ISO 2393:2014ISO 2781:2008 Ed 4ISO 18899:2013ISO 7619-1:2010 Ed 2ISO 9298:2017ISO 23529:2016ISO 2230:2002ISO 5725-2ISO 19983:2017ISO 23794:2015 ED3购买本文件时提供的所有当前修订版均包括在内。

BS ISO 4649:2017 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.Cross References:ISO 2393:2014ISO 2781:2008 Ed 4ISO 18899:2013ISO 7619-1:2010 Ed 2ISO 9298:2017ISO 23529:2016ISO 2230:2002ISO 5725-2ISO 19983:2017ISO 23794:2015 ED3All current amendments available at time of purchase are included with the purchase of this document.
