What is Impact Test and How Should It be Done?

Besides environmental causes, materials may fail when subjected to sudden applied impact due to pressure, load or stress. Be it a dry film of paint, varnish or other related product coating – these materials may crack or even peel from a substrate when exposed to sudden falling weight and pressure.

Here is where impact testing comes in.

Impact test is a method to evaluate the resistance of a material. It is usually carried out to:

1. Ensure compliance to specific test requirement
2. Determine the maximum weight or pressure that can be applied before the coating cracks or peels from its substrate

There are various types of impact testers designed to meet different test standards.

In general, impact testers usually consist of a solid base with guided tube support, together with different weights and impact heads. The selection of impact tester and type of tester heads are dependent on your business’s application and usage.
