NZS 5255:2014

The purpose of this standard is to verify the safety of existing gas installations by assessing their compliance with the Gas (Safety and Measurement) Regulations. Verification of safety will be achieved by focusing on the required performances that are specified in AS/NZS 5601 and NZS 5266, identifying areas of non-conformance and areas requiring improvement to ensure that installations are not unsafe to operate and are suitable for continued use, identifying common acceptable solutions (for example, systems, processes, and methods in AS/NZS 5601) appropriate to the installation that will attain the desired performances, and identifying alternative solutions that achieve the same performance while providing safe installations to consumers.
