ISO 34-1 measures the tear resistance of rubber materials using a trousers-type test specimen, primarily evaluating:

Test Parameters

• Tear Strength – Assesses the material’s resistance to tearing when force is applied to both ends of the notch.
• Crack Propagation Behavior – Simulates crack expansion from the notch to evaluate material stability and durability.

Applications

Tires & Transmission Belts – Simulates dynamic usage conditions to ensure tear resistance under high stress or repeated loading.
Shoe Soles & Industrial Rubber Products – Evaluates crack initiation and propagation in real-world applications, such as shoe soles and vibration pads that endure high loads.
