Compliance
Australian Standards
for precision cooling.
CRAC and precision cooling work in Australia is governed by a defined set of standards covering refrigerating systems, mechanical ventilation, water-loop microbial control, and refrigerant licensing. This page is a working reference.
Fire & Smoke
AS/NZS 1668.1
The use of mechanical ventilation and air-conditioning in buildings - Fire and smoke control
Fire-safety integration of mechanical air systems.
Relevance: Governs fire/smoke handling for CRAC and AHU systems within data halls and comms rooms.
AS 1851
Routine service of fire protection systems and equipment
Periodic service of fire protection systems.
Relevance: Applies where fire-suppression integrates with CRAC ventilation control (data hall pre-action / FM-200 systems).
Water Systems
AS/NZS 3666.1
Read detail
Air-handling and water systems of buildings - Microbial control - Design, installation and commissioning
Cooling tower and chilled-water loop microbial-control design.
Relevance: Mandatory for CDW CRAC systems and CHW plants connected to cooling towers.
AS/NZS 3666.2
Read detail
Air-handling and water systems of buildings - Microbial control - Operation and maintenance
Operation and maintenance of cooling-water systems for Legionella control.
Relevance: Mandatory ongoing compliance for any CDW or CHW plant with cooling tower / open evaporative system.
Refrigeration & Refrigerants
AS/NZS 5149.1
Read detail
Refrigerating systems and heat pumps - Definitions, classification and selection criteria
Refrigeration system classification and definitions.
Relevance: Foundation standard for all DX CRAC work.
AS/NZS 5149.2
Read detail
Refrigerating systems and heat pumps - Design, construction, testing, marking and documentation
Construction and testing requirements for refrigerating systems.
Relevance: Applies to CRAC commissioning and major refrigeration repair work.
AS/NZS 5149.3
Read detail
Refrigerating systems and heat pumps - Installation site
Installation requirements for refrigerating systems.
Relevance: Determines location, ventilation, and access requirements for CRAC indoor units and condensers.
AS/NZS 5149.4
Read detail
Refrigerating systems and heat pumps - Operation, maintenance, repair and recovery
Service and end-of-life refrigerant recovery requirements.
Relevance: Mandatory for all CRAC servicing and decommissioning work.
ARCtick licensing (ARC)
Read detail
Australian Refrigeration Council - Refrigerant Handling Licence
Mandatory licensing for any refrigerant handling work in Australia.
Relevance: All our CRAC technicians hold current RAC1/RAC2 licences. Required by federal regulation.
Energy Efficiency
NCC Section J
National Construction Code - Energy efficiency
Energy-efficiency requirements for new commercial buildings.
Relevance: Drives CRAC efficiency, set-points, and economiser strategies in new builds.
Industry Standards
ASHRAE TC 9.9
Thermal Guidelines for Data Processing Environments
Industry-standard thermal envelope (recommended and allowable) for IT equipment.
Relevance: Reference for set-points, supply air temperature, and humidity-band design.
AS 3814
Industrial and commercial gas-fired appliances
Where gas-fired heating or absorption systems integrate with cooling.
Relevance: Niche application for hybrid heat-rejection systems.
Work Health & Safety
WHS Act 2011 + state regulations
Work Health and Safety Act and Regulations
Federal WHS framework adopted by states.
Relevance: SWMS, JSA, and safe-work obligations for all CRAC service and installation work.
