ActiveThermoplastics pipes for the conveyance of fluids--Determination of resistance to rapid crack propagation (RCP)--Small-scale steady-state test(S4 test)
流体输送用热塑性塑料管材 耐快速裂纹扩展(RCP)的测定 小尺寸稳态试验(S4试验)
Application Summary AI generated
This standard specifies the small-scale steady-state (S4) test method for determining the resistance of thermoplastics pipes to rapid crack propagation (RCP). It is applied in the quality control and material evaluation of pipes used for fluid conveyance, particularly in gas and water distribution systems where sudden pressure drops or impacts could trigger catastrophic brittle fracture. The test is essential for ensuring pipeline safety under low-temperature or high-stress conditions.
