Air-handling and water systems of buildings – updated Standards suite
A suite of Standards protecting the community from the threat of legionnaires disease and other microbial organisms has
been improved. The joint Australian/New Zealand Standards series AS/NZS 3666 Air-handling and water systems of buildings covers microbial control in air handling and water systems in buildings. The objective of a new Standard in the suite,
AS/NZS 3666.4, is to provide a performance-based approach to air handling system maintenance to assist users in the
control of micro-organisms.
Parts one and two of the suite cover the design, installation, commissioning, operation, and maintenance of air handling
and water systems. Parts three and four are performance-based documents for maintenance – Part three covers cooling
water systems and Part four covers air-handling systems.
• Order AS/NZS 3666.1:2011 Air-handling and water systems of buildings – Microbial control – Part 1: Design, installation and commissioning
• Order AS/NZS 3666.2:2011 Air-handling and water systems of buildings – Microbial control – Part 2: Operation and maintenance
• Order AS/NZS 3666.3:2011 Air-handling and water systems of buildings – Microbial control – Part 3: Performance-based maintenance of cooling water
systems
• Order AS/NZS 3666.4:2011 Air-handling and water systems of buildings – Microbial control – Part 4: Performance-based maintenance of air-handling
systems (ducts and components).
