This Standard specifies minimum requirements for the safety, performance and use of gas appliance regulators. These requirements apply to self-acting gas pressure regulators up to 50 mm in size for use on natural gas (NG), simulated natural gas (SNG), town gas (TG), tempered liquefied petroleum gas (TLP) and liquefied petroleum gas (LPG), for inlet gas pressures up to 7 kPa and outlet pressures above 0.25 kPa. They may be of the lock-up type.
NOTE 1 Conformance of a regulator to the requirements of this Standard does not imply that it is acceptable for use without supplemental tests in its intended application.
NOTE 2 For regulators incorporated within a combination control, refer to AS 4624.
