SHT – Strain Hardening Test Modulus

Standard reference ISO 18488

03 April 2024

The measurement of the SHT modulus of polyethylene is added to the list of Accredited Tests, which is obtained from a stress-strain curve based on the traction ratio performed in a climatic chamber at 80°C.
The value of the SHT - Strain Hardening Test Modulus - allows characterization between materials and it has been demonstrated that this value must be at least 53 Mpa for the latest generation PE-100-RC polyethylene according to the product standards EN 12201, EN 1555, ISO 4427, ISO 4437 and EN 15494.
