ASTM D624 Die C uses a right-angle test specimen to measure the tear strength of rubber materials, primarily evaluating:

Test Parameters

• Tear Strength – Analyzes the material’s resistance to tearing at a right-angle notch.
• Crack Initiation Behavior – Tests the material’s durability and stability at the crack initiation point.

Applications

Seals & Gaskets – Evaluates tear resistance under localized high-stress conditions to ensure product stability.
Shoe Soles & Industrial Rubber Components – Assesses the reliability and lifespan of products like vibration pads and rubber sealing strips under heavy pressure or high-load environments.
