Supersedes: AS/NZS 1677.2:1998 Refrigerating systems and heat pumps - Safety and environmental requirements, Part 3: Installation site (ISO 5149-3:2014, MOD)

Draft Designation: DR AS/NZS 5149.3:2016
Document Number
5149
Description

The objective of this series of Standards 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)
Part 2: Design, construction, testing, marking and documentation (ISO 5149-2:2014, MOD)
Part 3: Installation site (ISO 5149-3:2014, MOD) (this Standard)
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 5149-3:2014, Refrigerating systems and heat pumps—Safety and environmental requirements, Part 3: Installation site, and 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 of AS/NZS 5149.1 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 part of ISO 5149’ should read ‘this Australian/New Zealand Standard’.
(b) A full point substitutes for a comma when referring to a decimal marker.

References to International Standards should be replaced by references to Australian or Australian/New Zealand Standards, as follows:

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

The term ‘normative’ has been used in this Standard to define the application of the appendix to which it applies. A ‘normative’ appendix is an integral part of a Standard.

Originated in Australia as part of AS CB3-1933. Final Australian edition AS 1677-1986. Originated in New Zealand as NZSS 1653:1962. Final New Zealand editions NZS 5235.1:1991 and NZS 5235.2:1988. AS 1677-1986, NZS 5235.1:1991 and NZS 5235.2:1998 jointly revised, amalgamated and redesignated in part as AS/NZS 1677.2:1998. Revised and redesignated in part as AS/NZS 5149.3:2016.
Scope

This part of ISO 5149 is applicable to the installation site (plant space and services). It specifies requirements for the site for safety, which could be needed because of, but not directly connected with, the refrigerating system and its ancillary components.

This part of ISO 5149 is applicable to new refrigerating systems, extensions or modifications of existing systems, and for used systems being transferred to and operated on another site. This part of ISO 5149 also applies in the case of the conversion of a system for another refrigerant.
