Gas Safety Program

Program Summary Card


Since 2004 the gas compliance market in Australia has been de-regulated and now organisations accredited by JASANZ, and recognised by the state regulators, can offer independent certification services.

The Gas Safety program applies to new gas appliances, at the time of manufacture, distribution or installation.  It is not applicable to “used” or second hand appliances.

AS3645 is the overall governance standard, which applies above all other standards (even if certification is not awarded to AS3645), and is subject to change. A list of the certification standards, are available from the Global-Mark Document Centre within the Gas Safety Program Information Brochure.

This certification program applies to the following gas appliance inlet pressures:

  • Natural Gas (NG) - 1.13kPa
  • Town Gas (TG) - 0.75kPa
  • Liquefied Petroleum Gas (LPG) - 2.75kPa (Propane, Butane or Universal gas - AS2658 appliances may vary)
  • Tempered Liquefied Petroleum Gas (LTP) - 0.75kPa

Gas Safety Categories:

  • I – Domestic Equipment
  • II – Commercial Equipment
  • III – Low volume products (<2 produced/month)
  • IV – Components
  • V – Camping and Leisure


  • Clients can transfer an existing JAS-ANZ Accredited certification to Global-Mark
  • Components may be certified to pressures nominated by client or to the applicable Australian standard
  • Type A appliance - a new gas appliance covered by the relevant appliance standard, with a gas consumption of no more than 500MJ/hr
  • Certification is based on a type-test process, including product testing and/or assessments acceptable to Global-Mark or the appropriate state Technical Regulator
  • The Certificate of Approval is valid for the product or a range of products with similar characteristics, materials and production processes, as tested. The term, similarly, is determined and based on Global-Mark judgement remains based
  • The Global-Mark certification mark must be affixed to the product, its packaging or supporting literature, together with the relevant standard and Global-Mark ID number
  • The certification mark must be used next to, or with, the manufacturer’s compliance label and must also include name of manufacturer/distributor, model/part number, date of certification, Global-Mark, type of gas to be used and other technical details of the gas appliance
  • The compliance label and certification mark must be permanently assigned to the appliance and must be visible to the end user
  • If any of the products critical components are changed, a new test report is required, with notification to Global-Mark so approval of the new/changed product can be granted prior to being implemented into production (using the design lock change form).


  • Minimum of yearly review of the product – typically product inspection together with quality controls
  • Review and approval of changes during the life cycle of the product (using the design lock change form)
  • On-going sampling and testing of the product (as the product changes, as defined in the SC, standard, or when approved test reports expire)
  • Physical inspection of the certified product(s) against requirements and documents in the compliance folder (including test reports and specifications)
