Scope
Scope: This document specifies the terms and definitions, symbols, abbreviations, materials, product classification, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of polyethylene pipes for water supply (hereinafter referred to as "pipes") made from 112-grade polyethylene compound as raw material and extrusion-molded. This document applies to polyethylene piping systems and their components for general-purpose pressure water transmission and drinking water distribution, where the water temperature does not exceed 40 °C and the maximum operating pressure (MOP) does not exceed 2.0 MPa. Note 1: The reference working temperature is 20 °C. For pressure reduction coefficients between 0 °C and 40 °C, please refer to Appendix A. Note 2: It is the responsibility of the purchaser to select the products specified in this section appropriately according to their specific application needs and in compliance with relevant regulations, standards, or norm requirements. This document applies to polyethylene pipes for water supply with a nominal outer diameter of 16 mm to 2,500 mm, manufactured from 112-grade polyethylene compound. Main Technical Contents: 1.
