Industrial valves - Test of flow resistance using water as test fluid

This document outlines the technical specifications for conducting resistance tests on industrial valves when water is utilized as the test fluid. It establishes the necessary procedures and criteria to ensure valves meet defined performance requirements under specific hydraulic conditions. The text details the test setup, fluid properties, pressure application methods, and measurement protocols required to assess the valve's ability to withstand pressure differentials while maintaining leak tightness. It covers various valve types commonly found in piping systems and specifies the acceptable limits for leakage rates during the evaluation process. The information provided within this publication serves as a guide for manufacturers, testing laboratories, and quality assurance personnel to verify the structural integrity and functional reliability of industrial valve components. By adhering to these guidelines, stakeholders can ensure consistent evaluation methods and comparable results across different facilities and product lines.
