Flexural Test



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

kJ/m2 ISO 179 

Tensile Test

MPa ISO 527 

Flexural Test


ISO 178


The flexural test measures the required force to bend a specimen under three point loading conditions. Flexural modulus is used as an indication of a specimen stiffness when flexed. It is also reported as the flexural strength or flexural yield strength.

Hardness Shore.D ISO 868
