本标准的目的是通过评估现有气体装置是否符合气体（安全和测量）法规来验证其安全性。安全验证将通过关注AS/NZS 5601和NZS 5266中规定的所需性能来实现，确定不合格区域和需要改进的区域，以确保装置操作不安全，并适合继续使用，确定适用于将达到预期性能的安装的通用可接受解决方案（例如，AS/NZS 5601中的系统、流程和方法），并确定在为消费者提供安全安装的同时实现相同性能的替代解决方案。

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.
