ISO 179-1 — Charpy impact strength of plastics (non-instrumented impact test)

← Back to all standards

ISO 179-1 defines the Charpy impact test for plastics under defined pendulum-impact conditions, measuring absorbed energy for notched or unnotched specimens. To match this to your program, talk with our team.

What ISO 179-1 Covers

It specifies edgewise and flatwise Charpy arrangements, notch types, and conditioning for plastics, giving a consistent measure of impact strength for compounds and moldings.

Why It Matters

Charpy impact strength is a common quality and formulation indicator for plastics; controlled notching and conditioning keep results comparable.
