Manually operated ball valves and closed bottom taper plug valves for gas installations for buildings

This document specifies technical requirements and test methods for manual ball valves and tapered plug valves used in gas installations within buildings. The scope covers valves designed for natural gas and liquefied petroleum gas, ensuring safety and performance under specified operating conditions. It defines essential characteristics such as pressure ratings, flow capacity, leakage rates, and durability under various mechanical and environmental stresses. The standard outlines procedures for verifying material quality, structural integrity, and functional reliability throughout the service life of the components. It applies to valves intended for domestic, commercial, and industrial applications where safe gas distribution is critical. Compliance with these specifications helps maintain consistent product quality across the supply chain. The text provides guidance for manufacturers, testers, and users regarding the design, manufacture, and acceptance of these specific valve types. By adhering to these technical provisions, stakeholders can ensure that equipment meets recognized safety benchmarks for gas appliance connections and distribution systems. This framework supports the harmonization of valve specifications in relevant sectors without addressing administrative or procedural aspects beyond the technical criteria themselves.
