Scope

This standard specifies the symbols and abbreviations, raw materials, product classifications, requirements, and tests for pipes (hereinafter referred to as "pipes") and pipe fittings produced with polypropylene (PP) resin as the main raw material for sewage and wastewater discharge in buildings. Methods, inspection rules, marking, packaging, transportation and storage. This standard applies to gravity discharge of sewage and wastewater inside buildings and buried pipes. It can also be used for industrial drainage pipes, taking into account the chemical resistance and heat resistance of the material. The application range of fluid temperature in pipes specified in this standard is 0°C ~ 65°C, and the instantaneous drainage temperature does not exceed 95°C.
