Abstract
This document specifies the terms and definitions, symbols and abbreviations, materials, product classification, requirements, test methods, inspection rules and marking, transportation, and storage of oriented hard polyvinyl chloride (PVC-O) pipes (hereinafter referred to as "pipes") and fittings used for pressure water transmission.
This document is applicable to pipes and fittings used in water supply, pressure drainage, sewage disposal, and irrigation systems where the water temperature does not exceed 45℃ and the maximum operating pressure (MOP) does not exceed 2.5 MPa, and the pipes and fittings are installed underground or aboveground (not directly exposed to sunlight).
Note: When the operating temperature does not exceed 25℃, the temperature reduction factor (ft) of the pressure is equal to 1. For the ft of the operating temperature between 25℃ and 45℃, please refer to Appendix B.
