该欧洲标准规定了在单个房间中的未管道/管道连续供应通风/供气通风单元或住宅通风中使用的单一住宅的空气动力学，声学和电力性能测试测量。 一般来说，这些单位包含: - 风扇 - 空气过滤器; - 控制系统。 单位还可能包括: - 格栅或空气分配装置; - 加热装置; - 太阳能或集热器（水或空气）; - 电气 - 水力 声音衰减器 旁路阻尼器 - 混合装置 补充加热也可以由太阳能集热器空气或地源热泵等提供，这些补充组件的性能不在本标准的范围内

This European standard specifies aerodynamic, acoustic and electrical power performance test measurements for un-ducted / ducted continuous supply ventilation / supply air ventilation units in a single room or a single dwelling used in residential ventilation. In general such units contain: - fan; - air filter; - control system. Units may also include: - grille or air distribution device; - heating device; - solar or thermal collectors (water or air); - electrical; - hydronic; - sound attenuators; - bypass dampers; - mixing devices. Supplementary heating may also be provided by solar air collector air or ground source heat pumps etc., the performance of these supplementary components are not covered by this standard.
