Valves for water supply - Fitness for purpose requirements and appropriate verification tests - Part 5: Control valves

This technical specification establishes specific suitability requirements and corresponding verification test procedures for control valves intended for use in water supply systems. It forms the fifth part of a comprehensive series addressing various valve types within the water distribution infrastructure. The document outlines essential criteria to ensure operational reliability and safety when these valves are installed in pressurized networks. Detailed methodologies for conducting validation tests are provided, allowing manufacturers and users to assess whether a valve product meets the defined performance benchmarks. These tests cover critical aspects such as pressure resistance, leakage rates, and functional response under defined conditions. The scope focuses exclusively on control valves, distinguishing their unique characteristics from other valve categories covered in related parts of the standard series. By adhering to the prescribed guidelines, stakeholders can verify that the components function correctly within the water supply environment without causing system failures. The content serves as a reference for quality assurance processes, ensuring consistency in product evaluation across different manufacturing facilities.
