JIS K6252 measures the tear resistance of rubber materials using a trousers-type test specimen, specifically analyzing crack initiation and propagation under dual-end tensile forces.

Test Parameters

• Tear Strength – Evaluates material resistance when force is applied to both ends of a trousers-shaped notch.
• Crack Propagation Resistance – Simulates material durability from initial crack formation to expansion.

Applicable Materials

• Suitable for rubber products subjected to dynamic stress or repeated loading.

Applications

Tires & Transmission Belts – Assesses tear resistance under repeated stretching or high dynamic loads.
Shoe Soles & Industrial Rubber Components – Simulates real-world performance in applications such as vibration dampers and gaskets under crack propagation conditions.
