Abstract: This paper analyzed and summarized the differences among the international standards ISO16422:2014, Chinese National Standard GB/T 41422—2022, European Standard EN 17176?2:2019, Australian/New Zealand Standard AS/NAS 4441:2017, Brazilian Standard ABNT NBR 15750:2020, and Indian Standard IS 16647:2017 in terms of their scope, terms and definitions, material, material classification, classification and selection of pipes, geometrical characteristics, and mechanical characteristics for PVC?O pipes. The differences among the North American standard system represented by the American standard ASTM F 1483?17 and the Canadian standard CSA B137.3.1:20 and the ISO standard system were also simply summarized. The application prospects of PVC?O pipes were proposed.
