本欧洲标准规定了测试湿度控制排气终端设备的实验室方法。 本欧洲标准适用于室内湿度下的所有受控设备，用于机械和自然动力住宅通风系统。例如，以下类型的设备: 湿度控制装置，带手动调节开口; 湿度控制装置固定; 湿度控制装置自调节压力差。 本欧洲标准描述了旨在表征的测试: 航空和潮湿性能; 声学特性（包括设备的噪声产生;设备的插入损耗;隔音）; 时间响应

This European Standard specifies laboratory methods for testing humidity controlled exhaust air terminal devices. This European Standard applies to all controlled devices on indoor humidity, used in mechanical and natural powered residential ventilation systems. For instance, devices of the following types: humidity controlled devices with a manually adjustable opening; humidity controlled devices with fixed setting; humidity controlled devices self-adjusting on pressure difference. This European Standard describes tests intended to characterize: aero and hygro-dynamic performance; acoustic characteristics (including noise production of the device; insertion loss of the device; sound insulation); time response.
