NZS 5261:2003

Gas installation

This document has been re-assessed by the committee, and judged to still be up to date.

Please note: Transitional provisions in the Gas (Safety and Measurement) Regulations 2010 allow NZS 5261:2003 Gas installation and NZS 5428:2006 LPG installations for non-propulsive purposes in caravans and boats to be used as alternatives to AS/NZS 5601 Gas installations up until 31 December 2012.

Legislative changes in 1992 removed the responsibility for inspection and certification of gas installations from the gas suppliers and instituted a regime of gas certification by a person authorized under the Plumbers, Gasfitters and Drainlayers Act. This Standard in Part 1 details the various aspects of a gas installation that contribute to its safety, stating performance criteria that shall be achieved to ensure that the legislative requirements for safety of gas installations are met. Part 2 gives the gasfitter more detailed information as a means of compliance with these performance criteria for small installations, and Part 3 gives references for use in the design and specification of larger installations. The means of compliance in Parts 2 and 3 are not the only means of compliance with the performance criteria in Part 1. Gas installations should be undertaken by persons authorized under the Plumber Gasfitters and Drainlayers Act 1976.
