ISO 34-2:2022 — Tear strength of vulcanized or thermoplastic rubber (small Delft test pieces)

← Back to all standards

ISO 34-2 is the test method for the tear strength of vulcanized or thermoplastic rubber using small (Delft) test pieces. To match this to your program, talk with our team.

What ISO 34-2 Covers

It measures rubber tear strength on small specimens, suited to limited material or micro-scale evaluation.

How the Test Is Run

A small Delft 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

Small-specimen tear testing extends evaluation to limited material; grips and a sensitive tensile frame are used.
