Specifies the designations and requirements for design, construction, testing and marking of safety devices required by AS 2030, to be fitted to gas cylinders and may be suitable for LPG fuel vessels covered by AS 1425. Provides for both metallic and non-metallic fusible plugs, bursting discs, pressure relief valves, and combinations of these. Includes requirements for performance rating of all types by type tests, as well as for material, design, construction, identification and marking.

This Standard specifies the designations, and the requirements for design, construction, testing, and marking of safety devices required by the AS 2030 series Standards to be fitted to gas cylinders.NOTES:1. Safety devices to this Standard are also suitable for use in accordance with AS 1425 for LP gas fuel vessels, but it should be noted that the performance values required by the AS 2030 series and AS 1425 are not necessarily the same. Where intended for use in accordance with AS 1425, the term 'gas cylinder' should be read to include 'LP gas fuel vessel'.2. Fitment of safety devices on cylinders used for certain gases is prohibited (see requirements for fitment of safety devices specified in the various Parts of AS 2030).
