ISO 180: Plastics — Izod impact strength (pendulum impact test)

← Back to all standards

ISO 180 is the test method for the Izod impact strength of plastics using a pendulum impact configuration. To match this to your program, talk with our team.

What ISO 180 Covers

It defines the Izod cantilever arrangement, notch types, and conditioning for plastics, giving a consistent measure of impact strength for molded and extruded materials.

Why It Matters

Izod impact strength ranks plastic toughness for acceptance and development; controlled notching and conditioning keep results comparable.

Reading the Designation

Cited as ISO 180 with its edition year. Confirm the edition and the specimen or notch requirements before finalizing fixtures and reporting. To configure an impact setup, request a quote.
