This Standard was prepared by the Standards Australia Committee ME/13, Industrial Fans, to supersede AS 4429(Int)—1996.

This Standard incorporates Amendment No. 1 (June 2002). The changes required by the Amendment are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure or part thereof affected.

This Standard is based on Draft European Standard prEN 12101-3, Smoke and heat control systems, Part 3: Specification for powered smoke and heat exhaust ventilators. The time/temperature performance requirements for smoke-spill fans used in buildings in Australia are specified by AS/NZS 1668.1:1998, The use of ventilation and airconditioning in buildings, Part 1: Fire and smoke control in multi-compartment buildings, and the range of time/temperature categories is not as wide as that specified in prEN 12101.3. This Standard provides methods for testing smoke-spill fans and their electric motors over the range covered by prEN 12101.3 and rates them accordingly.

The changes made to the Standard have been essentially editorial to better clarify the intended application of the test methodology and rating system. Tests carried out in accordance with AS/NZS 4429(Int):1996 are deemed to comply with the test requirements of this Standard.

The objective of this document is to provide a standardized methodology for the testing and rating of fans to be used in a smoke-spill mode for use by manufacturers and specifiers of these products.

The term 'informative' has been used in this Standard to define the application of the appendix to which it applies. An 'informative' appendix is only for information and guidance.
