AS/NZS 5601.1:2010

Specifies requirements and means of compliance for the design, installation and commissioning of gas installations that are associated with use or intended use of fuel gases such as natural gas, LP Gas, biogas or manufactured gas.

This Standard contains the mandatory requirements and means of compliance for the design, installation and commissioning of gas installations that are associated with the use or intended use of fuel gases such as natural gas, LP Gas, biogas or manufactured gas. The user is expected to be familiar with the properties and characteristics of those fuel gases and the principles of combustion, ventilation and flueing applicable to the safe installation and operation of gas appliances. For New Zealand, these requirements cover gas installations downstream of the point of supply (as defined in the Gas (Safety and Measurement) Regulations 2010.For Australia, these requirements cover gas installations downstream of the outlet of - (a) the consumer billing meter installation; (b) the first regulator on a fixed gas installation where an LP Gas tank or cylinder(s) is installed on site; or (c) the first regulator on site (if no meter is installed) where LP Gas is reticulated from off site storage.Where the term 'installation' is used it is deemed to include the pipework, appliances, flues, air ducts, ventilation and other ancillary items.Section 2 of this Standard contains the performance requirements for the design, installation, and commissioning of gas installations, including those operating at pressures exceeding 200 kPa. It includes, in Clause 2.6.4, some specific limitations as the performance requirements cannot be reliably met if those prohibitions are breeched.Sections 3 to 6 of this Standard contain a means of compliance for installations designed to operate with a gas supply pressure not exceeding 200 kPa. In Australia, approval for any variation to the requirements of Sections 3 to 6 or the normative appendices might need to be obtained from the appropriate Technical Regulator.In New Zealand, the Technical Regulator does not provide approvals for variations to the means of compliance in Sections 3 to 6. References to approval by the Technical Regulator are not applicable to New Zealand. The installation certifier is responsible for ensuring that the installation, including any variations, meets the requirements in Section 2.Where a Standard is cited as part of a means of compliance or in an Appendix, any Standard with equivalent performance requirements may be used as an alternative means of compliance in New Zealand.
