ASTM D624 uses a trousers-type specimen (Die T) to measure the tear strength of rubber materials, primarily evaluating:

Test Parameters

• Tear Strength – Analyzes the material’s resistance to tearing as the notch is pulled apart.
• Crack Propagation Behavior – Assesses the stability and durability of the material when stretched at both ends.

Applications

Tires & Transmission Belts – Evaluates crack propagation under high loads or dynamic movement to ensure product stability and longevity.
Shoe Soles & Industrial Rubber Products – Suitable for shoe soles, sealing gaskets, and other components exposed to irregular stress and tearing forces.
