标准摘要
[中文适用范围]: 本文件规定了硫化或热塑性橡胶辊套表观硬度的测定方法,以国际橡胶硬度(IRHD)表示。 该方法原则上类似于测定在特定力下操作的橡胶硬度的方法。 所使用的装置与 ISO 48-2 中描述的装置类似,具有专门设计用于应用于滚筒覆盖物和类似弯曲表面的底座。 注 对于某些滚筒,滚筒表面的橡胶厚度可能存在显着变化,这可能会影响测量的表观硬度。 [外文原描述]: This document specifies a method for the determination of the apparent hardness, expressed in International Rubber Hardness Degrees (IRHD), of vulcanized- or thermoplastic-rubber roller covers. The method is similar in principle to the methods used for the determination of the hardness of rubber in ISO 48-2 in that it consists essentially of measuring the depth of penetration of a spherical indentor operating under a specified force. The apparatus used is similar to that described in ISO 48-2, having a base specifically designed for application to roller covers and similar curved surfaces. NOTE With some rollers, there can be significant variation in the thickness of the rubber over the surface of the roller, which could affect the measured apparent hardness.
