Compression test

This test method is used to assess the behaviour of plastics when subjected to uniaxial compressive stress.

The test results are only comparable if the specimens are produced and tested under exactly the same conditions. They cannot therefore be transferred to any random plastic products. The elasticity modulus (E modulus) serves as a parameter for comparing different materials and is a measure of stiffness.

Results of the test method
Values for stress and strain such as:
  • Compressive modulus εc [MPA]
  • Compressive flow stress σY [MPA]
  • Compressive strength σM [MPA]
  • Nominal flow compression εcy [%]
  • Nominal compression at compressive strength εcM [%]
  • Stress-strain curve
