JIS K6252 uses a right-angle test specimen to evaluate the tear resistance of rubber materials, focusing on crack initiation and propagation under stress concentration conditions.

Test Parameters

• Tear Strength Measurement – Simulates crack propagation under localized stress concentration.
• Durability Assessment – Ensures material reliability under high-stress conditions.

Applicable Materials

• Rubber products used in high-stress environments, such as seals and shoe soles.

Applications

Shoe Sole Materials – Tests tear resistance under sharp stress conditions to extend product lifespan.
Rubber Gaskets & Vibration Pads – Evaluates crack resistance and stability under high-load conditions.
