本欧洲标准规定了用于住宅通风的风扇的空气动力学，声学和电能性能测试方法。这些方法主要涉及: - 安装在墙壁或没有任何管道的窗户中的通风扇; - 安装在管道下游的通风扇; - 安装在管道上游的通风扇; - 安装在管道中的通风扇; - 包含多个入口的通风扇。 对于声学性能测试，使用以下方法之一: - 管道法; - 混响室法 - 包络面法

This European Standard specifies aerodynamic, acoustic and electrical power performance test methods for fans used in residential ventilation. These methods primarily concern: - ventilation fans installed on a wall or in a window without any duct; - ventilation fans installed in the downstream of a duct; - ventilation fans installed in the upstream of a duct; - ventilation fans installed in a duct; - encased ventilation fans having several inlets. For acoustic performance testing one of the following methods is used: - in-duct method; - reverberant room method; - enveloping surface method.
