Australia adopts International Standards for Refrigeration Safety

The new standards will relate to a wide range of installations from low charge systems to very large industrial refrigeration systems.

The document will supersede the equivalent existing standards AS/NZS 1677.1 Refrigerating systems, Part 1: Refrigerant classification and AS/NZS 1677.2 Refrigerating systems, Part 2: Safety requirements for fixed applications which have been in use since 1998.

The new standards include:
AS/NZS ISO 817:2016 Refrigerants – Designation and safety classification
AS/NZS 5149.1:2016 Refrigerating systems and heat pumps - Safety and environmental requirements - Part 1: Definitions, classification and selection criteria.
AS/NZS 5149.2:2016 Refrigerating systems and heat pumps - Safety and environmental requirements - Part 2: Design, construction, testing, marking and documentation.
AS/NZS 5149.3:2016 Refrigerating systems and heat pumps - Safety and environmental requirements - Part 3: Installation site.
AS/NZS 5149.4:2016 Refrigerating systems and heat pumps - Safety and environmental requirements - Part 4: Operation, maintenance, repair and recovery.

The adoption of these standards is a really important step as the HVAC&R industry transitions to a low emission future.
