Gas Technical Regulators of Australia - High Risk Equipment Safety Critical Testing - Version 1.2

Oct 4, 2026

Gas Technical Regulators of Australia outlines the Gas Equipment Certification Scheme Rules requiring conformity assessment bodies to perform ongoing post-certification surveillance, including physical inspection and review of production instructions, markings, and relevant safety complaints or incidents. For equipment classified as high risk, surveillance also includes safety critical testing every two years. The document lists high-risk gas equipment types, sets out the required testing standards and clause requirements, and describes how the high-risk equipment list is reviewed bi-annually using field incidents, standards changes, stakeholder input, additional evidence, and recalls.

Gas Technical Regulators of Australia High Risk Equipment Safety Critical Testing The Gas Technical Regulators of Australia Gas Equipment Certification Scheme Rules require conformity assessment bodies (CABs) to conduct ongoing post-certification surveillance activities as part of the overall certification process. • For all products the post-certification surveillance consists of a physical inspection of a production sample, which involves a physical comparison of the sample against the relevant Technical Specification, a review of production instructions and markings, and consideration of any safety related complaints or incidents. • For gas equipment that has been classified by the technical regulators as high risk, in addition to the physical comparison, the equipment is required to undergo safety critical testing every 2 years as part of surveillance activities. This document provides a list of gas equipment that has been classified as high risk. It also specifies for each type of equipment the testing that is required to be undertaken once every 2 years on a representative sample. Products have been classified as high risk due typically either due to inherent design risks with the equipment that cannot be reliably assessed through the existing post surveillance physical inspection process, or due to field incidents that highlight a safety risk. The High Risk Safety Critical Testing equipment list shall be reviewed by the Gas Technical Regulators bi-annually at which time changes to the list and requirements will be considered. Changes to the list will consider a range of factors when determining if it necessary for equipment or requirements in the list to be modified. These include: • Field incidents and investigations • Standard changes • Input from industry stakeholders • Other relevant evidence demonstrating a change in risk • Recalls Consultation with industry stakeholders will be undertaken as part of the review process.

FAQs

What does post-certification surveillance include for certified gas equipment?

It involves a physical inspection of a production sample, including comparison against the relevant Technical Specification, review of production instructions and markings, and consideration of safety-related complaints or incidents.

How often must high-risk gas equipment undergo safety critical testing?

High-risk equipment must undergo safety critical testing every 2 years as part of surveillance activities, in addition to physical comparison.

Why are some gas products classified as high risk?

They are typically classified as high risk due to inherent design risks that cannot be reliably assessed by existing physical post-surveillance inspection, or due to field incidents that highlight a safety risk.
