AS 4429：Methods of test and rating requirements for smoke-spill fans
AS 4429 Test method of smoke-spill fans– Scope
This Standard classifies smoke-spill fans and sets out laboratory test methods and procedures used to rate their performance (and that of their motors). Fans are rated in terms of their suitability to operate continuously without significant loss of performance, for a specified time at a specified air temperature. This Standard deals only with laboratory type- testing and does not consider the testing of smoke-spill fans after they have been installed in a building.
