Air filters for general ventilation - Technical specifications, requirements and classification system based upon particulate matter efficiency (ePM) Ingestion-build-48183 as well as the non-preferred1 Scope This part of ISO 16890 establishes an efficiency classification system of air filters for general ventilation based upon particulate matter (PM). It also provides an overview of the test procedures, and specifies general requirements for assessing and marking the filters, as well as for documenting the test results. It is intended for use in conjunction with ISO 168902, ISO 168903 and ISO 168904. The test method described in this part of ISO
