流体输送用聚烯烃管材 耐裂纹扩展的测定 切口管材裂纹慢速增长的试验方法(切口试验)
Application Summary AI generated
This standard specifies a test method for determining the resistance of polyolefin pipes to slow crack growth by using a notched pipe specimen under constant internal pressure. It is applied in the quality control and material evaluation of polyethylene (PE) and polypropylene (PP) pipes used for fluid conveyance, such as water supply, gas distribution, and industrial piping systems. The notch test helps predict long-term durability and failure behavior under stress, ensuring pipes meet safety and performance requirements for buried or pressurized applications.
