Air filters for general ventilation - Part 2: Measurement of fractional efficiency and air flow resistance

This document specifies the aerosol production, the test equipment and the test methods used for measuring fractional efficiency and air flow resistance of air filters for general ventilation. It is intended to be used in conjunction with ISO 16890‑1, ISO 16890‑3 and ISO 16890‑4. The test method described in this document is applicable for air flow rates between 0,25 m3/s (900 m3/h, 530 ft3/min) and 1,5 m3/s (5 400 m3/h, 3 178 ft3/min), referring to a test rig with a nominal face area of 610 mm × 610 mm (24.0 inches × 24.0 inches). This document refers to particulate air filter elements for general ventilation having an ePM1 efficiency less than or equal to 99 % and an ePM10 efficiency greater than 20 % when tested as per the procedures defined within the ISO 16890 series. NOTE      The lower limit for this test procedure is set at a minimum ePM10 efficiency of 20 % since it is very difficult for a test filter element below this level to meet the statistical validity requirements of this procedure. This document is not applicable to filter elements used in portable room-air cleaners.

Air filters for general ventilation - Part 2: Measurement of fractional efficiency and air flow resistance

This document specifies the aerosol production, the test equipment and the test methods used for measuring fractional efficiency and air flow resistance of air filters for general ventilation.

It is intended to be used in conjunction with ISO 16890‑1, ISO 16890‑3 and ISO 16890‑4.

The test method described in this document is applicable for air flow rates between 0,25 m3/s (900 m3/h, 530 ft3/min) and 1,5 m3/s (5 400 m3/h, 3 178 ft3/min), referring to a test rig with a nominal face area of 610 mm × 610 mm (24.0 inches × 24.0 inches).

This document refers to particulate air filter elements for general ventilation having an ePM1 efficiency less than or equal to 99 % and an ePM10 efficiency greater than 20 % when tested as per the procedures defined within the ISO 16890 series.

NOTE      The lower limit for this test procedure is set at a minimum ePM10 efficiency of 20 % since it is very difficult for a test filter element below this level to meet the statistical validity requirements of this procedure.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
