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.

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 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.

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.

AS/NZS 3019 sets out the requirements for periodic assessment of existing electrical installations which are connected to a low voltage a.c. supply system (exceeding 50 V a.c. but not exceeding 1 000 V a.c.). Inspection and/or testing is intended, as far as reasonably practicable, to determine whether the installation and all its constituent equipment is in a safe condition for continued use.

This TECHnote discusses the requirements for microbial control in buildings and how these are addressed in NATSPEC.

This TECHnote addresses the selection of appropriate levels of insulation for piping, vessels and heat exchangers with curved surfaces.

Water sensitive urban design (WSUD) integrates planning and design of the urban water cycle, water supply, waste water, stormwater and groundwater management, urban design and environmental protection.

This TECHnote provides a checklist intended to assist the architect or building designer in the assessment of proposals for the design and installation of HVAC systems.
