Gas welding equipment. Safety devices - Devices not incorporating a flame (flashback) arrestor1 Scope This document specifies the general requirements and tests for safety devices for fuel gases and oxygen or compressed air which do not incorporate a flame (flashback) arrestor used downstream of manifold, cylinder and or pipeline outlet regulators, and upstream of blowpipes for welding, cutting and allied processes. This document does not specify the location of these devices in the gas system. This document is not applicable to safety devices
