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空气过滤器（EPA），高效空气过滤器（HEPA）和超低渗透空气过滤器（ULPA过滤器）。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人造测试气溶胶的颗粒计数方法确定效率的方法，并且允许这些过滤器在其效率方面的标准化分类。 EN 1822的这一部分适用于过滤元件的泄漏测试。详细描述本标准体内的程序，装置和试验条件的扫描方法对于H组和U组过滤器的完整范围是有效的，被认为是泄漏测定的参考试验方法。根据附件A的“油漏”测试和附件E中的“0,3μm至0.5μm粒子效率泄漏测试”可以替代地使用，但是仅用于定义类别的H组过滤器

This European Standard applies to efficient air filters (EPA), high efficiency air filters (HEPA) and ultra low penetration air filters (ULPA-filters) 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 an artificial test aerosol, and allows a standardized classification of these filters in terms of their efficiency. This part of EN 1822 applies to the leak testing of filter elements. The scan method which is described in detail regarding procedure, apparatus and test conditions in the body of this standard is valid for the complete range of group H and U filters and is considered to be the reference test method for leak determination. The 'Oil Thread Leak Test' according to Annex A and the '0,3 µm - 0,5 µm Particle Efficiency Leak Test' according to Annex E may be used alternatively but for defined classes of group H filters only.
