Applicable to the design, construction, and installation of refrigerating systems, including piping, components, materials, and ancillary equipment directly associated with such systems.

Specifies the requirements for the safety of persons and property, provides guidance for the protection of the environment, and establishes procedures for the operation, maintenance, and repair of refrigerating systems and the recovery of refrigerants.

The objective of this Standard specifies generic cabling within premises that comprise single or multiple buildings on a campus; it covers balanced cabling and optical fibre cabling.

This Standard provides safety rules for optical fibre communication systems and associated materials and equipment.

Adopts ISO/IEC14763-3:2014 to specify systems and methods for the inspection and testing of installed optical fibre cabling designed in accordance with premises cabling standards including ISO/IEC11801, ISO/IEC24764, ISO/IEC24702 and ISO/IEC15018.

AS/NZS 3084:2017 is amended as follows.

Specifies a simple means of referring to common refrigerants instead of using the chemical name, formula, or trade name. It also establishes a uniform system to be used in assigning the proper reference number and classification to refrigerants; the system for refrigerant classification is defined and physical data of common refrigerants listed.

This Standard provides an unambiguous system for assigning designations to refrigerants. It also establishes a system for assigning a safety classification to refrigerants based on toxicity and flammability data, and provides a means of determining the refrigerant concentration limit.

Specifies requirements for safety and environmental aspects in relation to operation, maintenance and repair of refrigerating systems and the recovery, reuse and disposal of all types of refrigerant, refrigerant oil, heat transfer fluid, refrigerating system and part thereof.

Provides specific guidance to architects, planners, designers, engineers, builders, installers, maintenance personnel, building owners, managers and users in the planning and installation of physical pathways and spaces in and between buildings to accommodate the equipment and cabling infrastructure necessary for communications; to the extent that this is not adequately covered for Australian and New Zealand purposes in AS/NZSISO/IEC 14763.2:2014.
