Basic Information
Scope
Main technical content: This standard specifies the basic requirements, technical requirements, test methods, inspection rules, marking, packaging, transportation, storage, and quality commitments for scratch-resistant non-excavation polyethylene water supply pipes (hereinafter referred to as "pipes") made from polyethylene compounding materials of at least PE100 grade and extruded into shape. The standard also specifies the requirements for raw materials. This standard applies to scratch-resistant non-excavation polyethylene water supply pipes with a nominal pressure of 1.0 MPa to 2.5 MPa and a nominal outer diameter of 110 mm to 1200 mm. The standard is suitable for pipes used in temperature not exceeding 40 °C, for the transportation of drinking water, and for general-purpose pressure water supply and drainage and sewage discharge, as well as for pipes used in excavation construction (conventional laying, sandless laying, etc.)
