BS ISO 4662:2017规定了两种测定橡胶回弹性的方法 介于30和85之间。它们是摆锤法和三点仪法。在摆锤法中，一端为球形的质量块撞击平整的试件，试件牢牢固定，但可以自由移动 隆起在撞击前后立即测量撞击质量的动能。使用三点仪法，平面试样受到安装在试样周围的半球体的冲击 支撑在轴上的圆盘，由一个轴转动- 轴心质量。原子的动能 在撞击前后立即测量撞击质量。交叉引用:ISO 23529:2016 ISO 48:2010 Ed 5ISO 19983ISO 9272:2005 Ed 2购买时可用的所有当前修订版均包含在本文件的购买中。

BS ISO 4662:2017 specifies two methods for determining the rebound resilience of rubber the hardness of which lies between 30 IRHD and 85 IRHD. They are the pendulum method and the tripsometer method.With the pendulum method, a mass with a spherical end impacts a flat test piece, firmly held but free to bulge. The kinetic energy of the impacting mass is measured immediately before and after impact.With the tripsometer method, a flat test piece is impacted by a hemisphere mounted on the periphery of a disc which is supported on an axle and caused to rotate by an off-axis mass. The kinetic energy of the impacting mass is measured immediately before and after impact.Cross References:ISO 23529:2016 ISO 48:2010 Ed 5ISO 19983ISO 9272:2005 Ed 2All current amendments available at time of purchase are included with the purchase of this document.
