Document Number

Description

This Standard incorporates Amendment No. 1 (March 2018) and No. 2 (July 2018). The changes required by the Amendment are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure or part thereof affected.

The objective of this Standard is to promote the safe design, construction, disposal, installation and operation of refrigerating systems.

This Standard does not address the hazards caused by products of combustion or decomposition of refrigerants. These products may include (but are not limited to) hydrogen fluoride. Exposure to these products can be harmful.

Lubricants and associated hazards are also not covered by this Standard. Lubricants can present significant health and environmental hazards.

AS/NZS 60079.14 is the current Australian/New Zealand Standard on electrical installations design, selection and erection in explosive atmospheres.

The AS/NZS 5149 series consists of the following parts under the general title, Refrigerating systems and heat pumps—Safety and environmental requirements:

Part 1: Definitions, classification and selection criteria (ISO 5149-1:2014, MOD) (this Standard)
Part 2: Design, construction, testing, marking and documentation (ISO 5149-2:2014, MOD)
Part 3: Installation site (ISO 5149-3:2014, MOD)
Part 4: Operation, maintenance, repair and recovery (ISO 5149-4:2014, MOD)

This Standard is an adoption with national modifications and has been reproduced from ISO 5149-1:2014, Refrigerating systems and heat pumps—Safety and environmental requirements, Part 1: Definitions, classification and selection criteria, and its Amendment No. 1 (2015), Correction of QLAV, QLMV, which has been added at the end of the document. This has been varied as indicated to take account of Australian/New Zealand conditions. The modifications are specified in the normative Appendix ZZ following the source text.

These modifications to the ISO source text are essential for compliance with this Australian/New Zealand Standard.

Appendix ZA provides guidance and examples on refrigerant charge limit determination for information only.

This Standard is to be read in conjunction with relevant legislation, regulation and national Refrigeration Industry Codes of Practice.

As this Standard is reproduced from an International Standard, the following applies:
(a) In the source text ‘this International Standard’ should read ‘this Australian/New Zealand Standard’.
(b) A full point substitutes for a comma when referring to a decimal marker.

Only normative references that have an alternative Australian or Australian/New Zealand Standard have been listed.

The terms ‘normative’ and ‘informative’ have been used in this Standard to define the application of the annex or appendix to which they apply. A ‘normative’ annex or appendix is an integral part of a Standard, whereas an ‘informative’ annex or appendix is only for information and guidance.
