Charpy Impact Strength



The mechanical properties of a polymer determine the range of usefulness and the service that can be expected from the material. Mechanical properties testing provides information on strength, impact resistance, hardness and fracture toughness.


Testing for mechanical properties is performed under various conditions. These are:











Izod Impact Strength

kJ/m2 ISO 180

Charpy Impact Strength


ISO 179


As like Izod impact, Charpy impact test is also for measuring the materials resistance to impact. Both of them use the same principle to test the Impact resistance of materials but there are several differences such as specimen position and dimension, point of strike, direction and type of Notch.

Tensile Test MPa ISO 527 
Flexural Stress MPa ISO 178 
Hardness Shore.D ISO 868
