BS ISO 48-5:2018规定了通过IRHD校准的袖珍硬度计测定硫化橡胶或热塑性橡胶压痕硬度的方法。此类仪表的使用主要用于控制目的，而非规范目的（规范见ISO 48-2）。通过将袖珍硬度计固定在支架上，可以提高精度。交叉引用:ISO 23529ISO 48-9ISO 48-2ISO 48-6ISO 868购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS ISO 48-5:2018 specifies a method for determining the indentation hardness of vulcanized or thermoplastic rubber by means of a pocket hardness meter calibrated in IRHD. The use of such meters is primarily intended for control, not specification, purposes (for specification, see ISO 48-2). It is possible to increase precision by fixing the pocket hardness meter on a support.Cross References:ISO 23529ISO 48-9ISO 48-2ISO 48-6ISO 868All current amendments available at time of purchase are included with the purchase of this document.
