本欧洲标准规定了在压差下运行的湿度控制进气口的实验室方法。 适用于位于一室之间的所有设备，并受室内湿度控制。例如，以下类型的设备: 湿度控制装置固定; 可手动打开或关闭的湿度控制装置; 湿度控制装置自调节压力差。 它描述了旨在表征的测试: 航空和潮湿性能; 关闭时气密性（可关闭湿度控制进气口）; 占用区空气扩散; 隔音; 时间响应。 本欧洲标准不适用于空气过滤，冷凝风险和噪音生产的评估

This European Standard specifies laboratory methods for testing humidity controlled air inlets operating under pressure differences. It applies to all devices located between one room and outside and controlled on indoor humidity. For instance, devices of the following types: humidity controlled devices with fixed setting; manually openable or closable humidity controlled devices; humidity controlled devices self-adjusting on pressure difference. It describes tests intended to characterise: aero and hygro-dynamic performance; air tightness when closed (for closable humidity controlled air inlet); air diffusion in the occupied zone; sound insulation; time response. This European Standard does not apply to the evaluation of air filtration, condensation risk and noise production.
