Abstract
Outlines a performance-based approach to the maintenance of cooling water systems with respect to the control of microorganisms, including Legionellae within such systems. This approach combines automatically regulated water treatment with monitoring, assessment and control strategies to help create a low-risk environment within the cooling water system. This Standard provides a performance-based alternative to the prescriptive requirements of AS/NZS 3666.2 for the maintenance of cooling water systems.
Scope
This Standard outlines a performance-based approach to the maintenance of cooling water systems with respect to the control of microorganisms, including Legionellae, within such systems. This approach combines automatically regulated water treatment with monitoring, assessment and control strategies to help create a low risk environment within the cooling water system.
The provisions of this Standard are an alternative to the prescriptive requirements of AS/NZS 3666.2 for the maintenance of cooling water systems.
NOTE: This Standard addresses only the performance of maintenance programs for cooling water systems and is to be read in conjunction with Part 1 and the relevant clauses of Part 2. Aspects such as maintenance manuals, records, log books, safety procedures, and the like, are as important for the application of this Standard as they are for a prescriptive approach to maintaining a clean system.
