标准摘要
[中文适用范围]: 本文件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:摆锤法和行程计法。 摆锤法:一个带有球形端的质量块撞击一个被牢固固定但可以自由膨胀的平面试样。测量撞击质量块在撞击前和撞击后的动能。 行程计法:一个平面试样被安装在圆盘边缘上的半球撞击,圆盘由轴支撑并由偏心质量引起旋转。测量撞击质量块在撞击前和撞击后的动能。 [外文原描述]: 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.
