ActivePolyolefin pipes for the conveyance of fluids—Determination of resistance to crack propagation—Test method for slow crack growth(notch test)
流体输送用聚烯烃管材 耐裂纹扩展的测定 慢速裂纹增长的试验方法（切口试验）
Application Summary AI generated
This standard specifies a notch test method for determining the slow crack growth resistance of polyolefin pipes used in fluid conveyance systems. It is applied by manufacturers and testing laboratories to evaluate the long-term durability and failure resistance of polyethylene (PE) and polypropylene (PP) pipes under sustained internal pressure. The test is critical for quality control and material selection in water supply, gas distribution, and industrial piping applications.
