Regulating authorities

Basic concepts

This standard does not specify the location of these devices in the gas system

Initial selection for normal use

The effect of the thermal barrier material on the dimensional tolerances is covered by BS EN 12020-2 although the actual thermal barrier material itself is not (see BS EN 14024)

Gas welding equipment. Safety devices - Incorporating a flame (flashback) arrestor Ingestion-build-78747 Regulating authoritiesBS EN 730 1 specifies the general requirements and tests for safety devices for fuel gases and oxygen or compressed air incorporating 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 standard does not specify the location of these devices in the gas system. Nor does it include requirements for safety devices which do not
