Rubber, vulcanized or thermoplastic — Determination of hardness — Part 5: Indentation hardness by IRHD pocket meter method
硫化橡胶或热塑性橡胶硬度的测定第5部分:用IRHD袖珍硬度计法测定压痕硬度
This document 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.
