AS/NZS 5601.1 Gas Pressure Standards & Compliance Certification
AS/NZS 5601.1 Gasfitting Safety & Pressure Thresholds
Under AS/NZS 5601.1 Gas Installations Standards and NSW Fair Trading Gasfitting Rules, Sydney Natural Gas systems operate at 1.13 kPa (11.3 mbar) working pressure, while LPG systems run at 2.75 kPa (27.5 mbar). Before issuing a mandatory NSW Fair Trading Gas Compliance Certificate, our licensed gas fitters conduct a 20-minute digital static pressure decay test to verify zero gas leakage.
