This ISO 48 International Standard provides guidance on the determination of the hardness of vulcanized and thermoplastic rubbers. It is intended to provide an understanding of the significance of hardness as a material property and to assist in the selection of an appropriate test method.

Standards referenced as follow:

ISO 48, Rubber, vulcanized or thermoplastic — Determination of hardness (hardness between 10 IRHD and 100 IRHD)

ISO 7267-1, Rubber-covered rollers — Determination of apparent hardness — Part 1: IRHD method

ISO 7267-2, Rubber-covered rollers — Determination of apparent hardness — Part 2: Shore-type durometer method

ISO 7267-3, Rubber-covered rollers — Determination of apparent hardness — Part 3: Pusey and Jones method

ISO 7619-1, Rubber, vulcanized or thermoplastic — Determination of indentation hardness — Part 1: Durometer method (Shore hardness)

ISO 7619-2, Rubber, vulcanized or thermoplastic — Determination of indentation hardness — Part 2: IRHD pocket meter method

ISO 18898, Rubber — Calibration and verification of hardness testers

ISO 27588, Rubber, vulcanized or thermoplastic—Determination of dead-load hardness using the very low rubber hardness (VLRH) scale
