ASTM D624 Die B is used to measure the tear strength of rubber materials, primarily evaluating:

Test Parameters

• Tear Strength – Assesses the material’s resistance to tearing during crack propagation.
• Crack Propagation Behavior – Analyzes the tearing pattern under different load conditions.

Applications

Seals & Shoe Soles – Ensures durability and tear resistance under heavy pressure.
Rubber Components – Evaluates reliability under high-stress environments, such as vibration pads and gaskets.
