标准范围

本文件规定了硫化橡胶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ISO 48-2中用于测定橡胶硬度的方法，因为它主要包括测量在规定力下工作的球形压头的穿透深度。所使用的仪器与ISO 48-2中所述的仪器类似，其底座专门设计用于辊盖和类似曲面。注:对于某些辊子，辊子表面的橡胶厚度可能会发生显著变化，这可能会影响测得的表观硬度。

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.
