Impact strength is the resistance of a material to cracking under dynamic load. The test temperature is an important factor in the impact tests.

We perform impact tests at room temperature, at temperatures down to -60oC and at the temperature of liquid nitrogen (-196oC). Typically, decreasing the test temperature increases the brittleness of the material.

The tests are performed on standardized notched (V or U) specimens, on a pendulum impact tester with a standard striker with a blade with a radius rounding edge of 2 mm or 8 mm. After the test, it is possible to determine the lateral extension (LE) of the specimens.

Impact test is performed in compliance with:

  • PN-EN ISO 148-1
  • PN-EN ISO 9016
  • ASTM E23
