Full title and description

ISO 7619-1:2010 — Rubber, vulcanized or thermoplastic — Determination of indentation hardness — Part 1: Durometer method (Shore hardness). This part specifies the durometer (Shore) method for measuring the indentation hardness of vulcanized or thermoplastic rubber using the A, D, AO and AM scales and gives requirements for instruments, test pieces, test procedure and precision data.

Abstract

ISO 7619-1:2010 defines procedures for determining Shore (durometer) hardness of rubber and thermoplastic elastomers. It covers instrument types and tolerances, test-piece preparation and thickness requirements, timing and reading procedures, calibration/verification guidance and precision information (Annex A). The standard was issued as the second edition in 2010.

Scope

This part of ISO 7619 specifies the durometer (Shore) method for the determination of indentation hardness of vulcanized or thermoplastic rubber. It applies to durometers using the A scale (normal hardness), D scale (high hardness), AO scale (low hardness and cellular rubbers) and AM scale (thin test pieces in the normal-hardness range). The document covers instrument characteristics and tolerances, preparation and conditioning of test pieces, test procedure (including timing and reading), calibration/verification and precision data.

Key topics and requirements

• Defined durometer types and indentor geometries (types A, D, AO and AM) and their dimensional tolerances.
• Requirements for calibrated spring force and indicating devices; equations relating applied force to hardness readings for the instrument types.
• Test-piece preparation and minimum thickness rules (e.g., ≥6 mm for A/D/AO, ≥1.5 mm for AM) and guidance on multilayer test pieces.
• Conditioning temperature and environmental considerations for valid results.
• Timing and reading procedures, including optional automatic timing devices to improve precision.
• Precision data and measurement uncertainty guidance provided (Annex A / amendment history included in the 2010 revision).
• Notes on comparability between Shore durometer values and IRHD; the standard advises caution when correlating different hardness measurement systems.

Typical use and users

Used by materials test laboratories, quality control departments in rubber and elastomer manufacturing, product designers and suppliers of elastomer components (seals, gaskets, hoses, vibration mounts). The standard supports specification, incoming inspection and acceptance testing where Shore hardness is a material property or quality characteristic.

Related standards

ISO 7619 is a multipart series; Part 2 covers the IRHD pocket meter method. Other relevant standards referenced for calibration and test-piece preparation include ISO 18898 (instrument calibration) and ISO 23529 (preparation of test pieces). ISO 48 (hardness measurements in IRHD range) is also related for comparison and broader hardness testing context.
