AS 4603: Flashback Arrestors for Gas Welding and Cutting
This standard specifies the requirements for flashback arrestors used in oxy-fuel gas systems. It includes guidelines for testing and maintaining these devices to prevent dangerous gas or flame reverse flows. For proper maintenance of flashback arrestors, they must undergo flashback arrestor testing at least once or twice a year to ensure that they are working properly.
