GB/T 531.2-2009 "Rubber, vulcanized or thermoplastic - Determination of indentation hardness - Part 2: Portable hardness meter method" specifies the method for measuring the indentation hardness of vulcanized or thermoplastic rubber using a portable rubber international hardness durometer (IRHD). This instrument directly reads the IRHD hardness value by measuring the depth of penetration of a specified shape indenter under a specific spring force into the rubber, and is suitable for rapid testing in the field or laboratory.
