Specifies the uniform minimum requirements for manufacturers, designers, regulatory authorities, testing laboratories and similar organizations for the safety, performance and use of over-pressure and under-pressure cut off devices up to 150 mm size. These devices are intended for use with natural gas, town gas, tempered liquefied petroleum gas and liquefied petroleum gas.

These requirements apply to over-pressure and under-pressure cut off devices up to 150mm size for use on natural gas (NG), simulated natural gas (SNG), town gas (TG), tempered liquefied petroleum gas (TLP) and liquefied petroleum gas (LPG), intended to be fitted in the gas supply downstream of the master meter or an LPG first stage pressure regulator.These requirements cover over-pressure and under-pressure cut off devices intended for installation into a pipeline either directly or as part of a gas pressure regulator. Over-pressure cut off devices generally serve to protect equipment downstream of regulators from being pressurized beyond its rated working pressure if the regulator fails.These requirements do not cover devices incorporating electrically operated safety shut off valves actuated by pressure switches. Requirements for these items are covered in AG213 (to be AS4628) and AG214 (to be AS4629).Compliance with these requirements does not imply acceptability for use without supplemental tests in an intended application.
