Scope

This document specifies the terms and definitions, design and materials, technical requirements, test methods, factory tests, instructions, and markings for flame arresters used in welding, cutting, and related processes with gas, oxygen, or compressed air. Flame arresters are applied to the downstream outlets of gas storage tanks, manifold systems, or pressure reducers in gas path systems, and the upstream inlets of welding and cutting torches.
This document does not specify the specific installation locations of flame arresters in gas path systems.
This document does not apply to other safety devices without flame arresters as specified in GB/T 46082.2.
This document does not apply to pre-mixed gas pipeline systems of oxygen and gas, or air and gas. For example, the downstream gas pipelines of gas mixers or hydrogen and oxygen gas generators from water electrolysis.
