Air-Handling and Water Systems of Buildings - Microbial
Control - Operation and Maintenance
AS/NZS 3666 Part 2 - The Australian
Standard/New Zealand Standard AS/NZS 3666 Part 2 is
concerned with microbial control issues associated with
air handling and water systems in commercial buildings.
AS/NZS 3666 Part 2 identifies the minimum requirements
for the operation and maintenance of such building systems.
Although originally developed for commercial building
services systems AS/NZS 3666 Part 2 can also be applied
to other commercial or industrial air handling and water
systems, and to domestic systems incorporating cooling
water equipment.
Operational and Maintenance Requirements
Whilst AS/NZS 3666 Part 2 identifies the minimum operational
and maintenance requirements associated with the control
of microbial growth in air handling and water systems
of commercial buildings; design, installation and commissioning
issues are dealt with in AS/NZS
3666 Part 1.
For additional information concerning the control of
microbial growth in air handling and water systems of
commercial buildings, HB 32 should be consulted.
