本欧洲标准适用于通风和空调以及技术过程领域中使用的高效颗粒和超低渗透空气过滤器（EPA，HEPA和ULPA）。用于洁净室技术或制药行业的应用。 它建立了一种基于使用液体（或固体）测试气溶胶的颗粒计数方法来确定效率的程序，并且允许这些过滤器的效率（局部效率和整体效率）的标准化分类

This European Standard applies to high efficiency particulate and ultra low penetration air filters (EPA, HEPA and ULPA) used in the field of ventilation and air conditioning and for technical processes, e.g. for applications in clean room technology or pharmaceutical industry. It establishes a procedure for the determination of the efficiency on the basis of a particle counting method using a liquid (or alternatively a solid) test aerosol, and allows a standardized classification of these filters in terms of their efficiency, both local and integral efficiency.
