High efficiency air filters (EPA, HEPA and ULPA) - Part 4: Determining leakage of filter elements (scan method)
N DS/EN 1822-4
Annotation
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.

Высокоэффективные фильтры воздуха (EPA, HEPA и ULPA) - Часть 4: Определение утечки фильтрующий элементов (сканируют метод),
Этот европейский стандарт относится к эффективным фильтрам воздуха (EPA), высокоэффективные фильтры воздуха (HEPA) и крайние низкие фильтры воздуха проникновения (ULPA-фильтры), используемые в области вентиляции и кондиционирования воздуха и для технических процессов, например, для применений в чистой технологии помещения или фармацевтической промышленности. Это устанавливает порядок для определения эффективности на основе метода подсчета частицы с помощью искусственного испытательного аэрозоля и позволяет стандартизированную классификацию этих фильтров с точки зрения их эффективности. Эта часть 1822 EN относится к испытанию на герметичность фильтрующий элементов. Метод сканирования, который описан подробно относительно процедуры, аппарата и условий испытаний в организации этого стандарта, действителен для полного спектра фильтров группы H и U и считается справочным методом испытаний для определения утечки. 'Нефтяное Испытание на герметичность Нити' согласно приложению A и '0,3 µm - 0,5 Испытания на герметичность Эффективности Частицы µm' согласно Приложению E могут использоваться альтернативно, но для определенных классов группы H фильтрует только.
