AS 4429：Methods of test and rating requirements for smoke-spill fans
AS 4429：排烟风机的测试方法和等级要求
AS 4429 排烟风机的测试方法和等级要求 – 适用范围
本标准对溢油烟风机进行了分类，并规定了用于评估其性能（及其电动机性能）的实验室测试方法和程序。 根据风扇在指定的温度下在指定的时间内连续运行而不会造成性能严重损失的额定值，对风扇进行评级。 本标准仅涉及实验室型式试验，不考虑将排烟风扇安装在建筑物中后的测试。
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.
