标准范围

ISO 4662:2009规定了两种测定硬度介于30 IRHD和85 IRHD之间的橡胶回弹性的方法。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，试件固定牢固，但可以自由膨胀。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圆盘外围的半球体的冲击，圆盘由轴支撑，并由离轴质量引起旋转。在撞击前后立即测量撞击质量的动能。

ISO 4662:2009 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.
