Scope

Scope: This document specifies the terms and definitions, classification, technical requirements, test methods, sampling inspection and inspection items, marking, packaging, and transportation of anti-pollution partition valves (hereinafter referred to as partition valves). This document applies to anti-pollution partition valves connected to dedicated water supply systems. Main technical content: Anti-pollution partition valves are protective devices installed in various piping systems to prevent downstream liquids from flowing back to the upstream, thereby avoiding backflow pollution. This standard specifies the terms and definitions, classification, technical requirements, test methods, sampling inspection and inspection items, marking, packaging, and transportation of anti-pollution partition valves. This standard references European standards and combines with China's actual usage conditions and standardization development directions. It provides detailed explanations of test items such as appearance, hygiene, backflow protection function, risk requirements of protection points, air gap test, durability performance, bending strength, sealing performance, mechanical characteristics, reliability, hydraulic characteristics, and compatibility with disinfected products, providing a basis for the design, production, sales, and use of anti-pollution partition valves.
