Application Summary AI generated
This standard specifies the requirements and test methods for plastics piping systems used in the trenchless renovation of underground non-pressure drainage and sewerage networks, specifically for lining with close-fit pipes. It is applied in municipal infrastructure projects where existing damaged or leaking sewer and drainage pipes are rehabilitated by inserting a tightly fitting plastic liner without excavation. The standard ensures the mechanical performance, dimensional compatibility, and long-term durability of the lining system under in-service conditions.
