# Charpy impact tests

## You wish to perform Charpy impact tests on your polymers...

The purpose of the Charpy impact bending test is to measure the resistance of a material to failure. It is frequently called Charpy impact test or even Charpy test. It is preferably performed on an unnotched specimen.

In the Charpy impact test the specimen is positioned horizontally.

The ISO 179 standard specifies a method for determining the Charpy impact strength of plastics. A pendulum sheep animated by a determined speed causes by a single percussion the rupture of a specimen (smooth or notched) placed between two supports. The purpose of the test is to determine the energy required to break the specimen.

### The pendulum impact tester for Charpy impact tests

The pendulum impact tester is the equipment used to perform Charpy impact tests.

It is used to measure the energy absorbed by a material during fracture after impact. This mechanical test is essential to evaluate material toughness, resilience, and impact behavior, particularly in industrial and metallurgical sectors.

## FILAB laboratory can assist you in performing Charpy impact tests on your polymers

With the support of a partner laboratory, the FILAB laboratory can assist you in carrying out Izod impact tests on your polymers in accordance with the ISO 179 standard.

We also offer other physicochemical and thermal analysis services on polymers such as
