ActivePolyethylene materials for piping systems—Determination of Strain Hardening Modulus in relation to slow crack growth
管道系统用聚乙烯材料 与慢速裂纹增长相关的应变硬化模量的测定
Application Summary AI generated
This standard specifies a test method for determining the strain hardening modulus of polyethylene materials, which is used to evaluate their resistance to slow crack growth. It is applied in the quality control and material selection for polyethylene piping systems, particularly in gas and water distribution networks where long-term durability under sustained pressure is critical. The standard is relevant for manufacturers, testing laboratories, and engineers assessing the performance of PE pipe grades.
