Scope
This standard specifies the materials, product classification and specifications, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of pipes and fittings made from polyethylene resin as the main raw material, which are extruded into pipes and moulded or processed by secondary processing (for sewage and wastewater discharge).
This standard applies to gravity sewage and wastewater discharge systems and siphon-type roof rainwater drainage systems in buildings.
Under non-pressure conditions, the temperature range of fluids in high-density polyethylene pipes specified by this standard is 0°C to 65°C, and the instantaneous drainage temperature should not exceed 95°C; the environmental temperature range of high-density polyethylene pipes is -40°C to 65°C.
