Valves for water supply - Fitness for purpose requirements and appropriate verification tests - Part 4: Air valves

This technical specification outlines the applicability requirements and corresponding verification tests specifically designed for air valves used in water supply systems. It addresses the technical criteria necessary to ensure these components function effectively within pressurized water networks, focusing on their ability to manage air pockets and prevent vacuum conditions that could compromise system integrity. The document details the methodology for evaluating performance under various operational scenarios, including pressure fluctuations and air release mechanisms. It establishes clear parameters for manufacturing and installation practices to maintain safety and efficiency standards across infrastructure. The scope covers specific testing procedures to validate compliance with established engineering principles relevant to fluid transport systems. By adhering to these guidelines, stakeholders can verify that air valves meet the necessary benchmarks for reliability and durability. This framework supports consistent quality control measures throughout the lifecycle of water distribution components, ensuring seamless integration into broader network designs without direct reference to specific regulatory bodies or exact publication dates.
