WK94432 - New Test Method for Strain Hardening Modulus (SHM) in relation to slow crack growth for polyethylene materials in piping systems

Work Item

ASTM WK94432

New Test Method for Strain Hardening Modulus (SHM) in relation to slow crack growth for polyethylene materials in piping systems

1. Scope

Using the ISO test method 18488-2015 as guidance, develop an ASTM test method for strain hardening modulus (SHM) that can be used to predict slow crack growth properties of PE materials used in piping systems

Keywords

Strain Hardening Modulus (SHM), slow crack growth properties

Rationale

As HDPE materials continue to improve, the Strain Hardening Modulus (SHM) test method can provide an efficient method to predict slow crack growth properties of HDPE materials used in pressure piping systems
