BS ISO 48-7:2018规定了一种测定硫化橡胶或热塑性橡胶辊盖表观硬度的方法，用肖氏硬度表示，用于仅要求中等精度的测量。所使用的方法和设备基本上是ISO 48-4中所述的方法和设备，在这种情况下，测量是在经过处理的橡胶覆盖辊的曲面上进行的，而不是在平面试件上进行的。规定了肖氏A型和D型仪器，后者用于测量高硬度辊。交叉引用:ISO 48-4ISO 23529ISO 6123-1购买时可用的所有现行修订版均包含在本文件的购买中。

BS ISO 48-7:2018 specifies a method for the determination of the apparent hardness of vulcanized- or thermoplastic-rubber roller covers, expressed in Shore hardness, for measurement where only medium precision is required. The method and apparatus used are essentially those described in ISO 48-4, the measurements in this case being made on the curved surface of the conditioned rubber-covered roller rather than on a flat test piece. Shore type A and type D instruments are specified, the latter being used for measurements on rollers of high hardness.Cross References:ISO 48-4ISO 23529ISO 6123-1All current amendments available at time of purchase are included with the purchase of this document.
