في 1822 is a European standard series for the classification and performance testing of high-efficiency air filters. It applies to EPA, HEPA and ULPA filters used in ventilation, air-conditioning and technical processes, including cleanroom and pharmaceutical applications.
The standard evaluates performance at the most penetrating particle size, أو MPPS. It should not be described as a general standard for ordinary residential or commercial HVAC filters, and it is not the same as an installed cleanroom integrity test.
| Group | فصول | Classification evidence |
| EPA | E10-E12 | Integral efficiency at MPPS. Local leak testing is not required for classification. |
| HEPA | H13-H14 | Integral efficiency and the applicable local leakage requirement. |
| ULPA | تحت 15- تحت 17 | Stricter integral efficiency and local leakage requirements at MPPS. |
في 1822 factory testing evaluates an individual filter element before installation. After the filter is mounted in a ceiling, housing or air-handling system, an installed integrity test also checks the gasket, ختم هلام, frame and possible bypass paths. Installed-system verification uses a separate project or cleanroom test procedure and does not replace the manufacturer’s filter classification.
A complete configuration may require controlled airflow, توليد الهباء الجوي, أخذ العينات المرجعية المنبع, a detector with sufficient particle-size range and sensitivity, automatic scanning motion, leak mapping and report generation. The correct detector and aerosol arrangement depend on the filter class and the lowest penetration that must be measured.
SCPUR configures the SC-L8023 و SC-L8023U systems according to filter class, أبعاد, تدفق الهواء, نطاق الجسيمات, scanning arrangement and production throughput.
