AS/NZS 1668.2 Compliance for CRAC and Server Rooms
AS/NZS 1668.2 compliance for CRAC, server rooms and data centres. Ventilation design, outside air, indoor air quality and service checks.
AS/NZS 1668.2 covers mechanical ventilation for indoor air quality in buildings. For CRAC and precision cooling rooms, it matters because cooling equipment is often designed around recirculated air, but the room still needs a documented ventilation approach.
CRAC Services checks AS/NZS 1668.2 touchpoints during design, commissioning and maintenance: outside air strategy, pressure relationships, air paths, ventilation plant condition and how the CRAC room interfaces with the broader building HVAC system.
Compliance checks
What we check on CRAC sites
01
Confirm whether the room uses dedicated outside air, building HVAC transfer air or sealed recirculation.
02
Check supply and return air paths for blocked grilles, short cycling and hot air recirculation.
03
Record setpoints and temperature readings against the intended room use.
04
Confirm BMS alarms and ventilation alarms are mapped for facilities response.
05
Document any ventilation defects that affect CRAC performance or indoor air quality.

FAQs
Does AS/NZS 1668.2 apply to server rooms?
Yes, where the server room forms part of a building mechanical ventilation system or has a defined outside air strategy. The standard is not a CRAC equipment manual, but it affects the design and compliance notes around ventilation, air paths and indoor air quality.
Is AS 1668 compliance the same as CRAC maintenance?
No. CRAC maintenance checks the cooling equipment. AS/NZS 1668.2 compliance checks whether the room ventilation approach is suitable and documented. In practice, both need to be reviewed together because poor ventilation or air paths can make a correctly serviced CRAC unit underperform.
