ISO 34-1 Tear Strength Testing for Rubber (Trouser, Angle, Crescent)

← Back to all standards

ISO 34-1 is the test method for the tear strength of vulcanized or thermoplastic rubber using trouser, angle, and crescent specimens. To match this to your program, talk with our team.

What ISO 34-1 Covers

It measures the force to tear rubber with several specimen geometries, giving tear strength for elastomer specification and development.

How the Test Is Run

A rubber tear specimen is pulled at a controlled rate until it tears, and the tear strength is calculated from the force and thickness.

Why It Matters

Tear strength governs rubber durability; grips and a tensile frame suited to elastomers are used.
