ISO 813
Rubber, vulcanized or thermoplastic — Determination of adhesion to a rigid substrate — 90° peel method


ISO 813 defines the methodology for measuring elastomer hardness using Shore durometers on the A and D scales. This international standard applies to vulcanized rubbers, thermoplastic elastomers, and related polymeric materials, encompassing both laboratory specimens and finished products. The test procedure involves pressing a standardized indenter into the material surface and determining penetration depth to establish hardness values. Essential for quality control and mechanical property characterization, ISO 813 ensures consistent hardness assessment across elastomeric materials in industrial applications.
