Air filters for general ventilation - Part 1: Technical specifications, requirements and classification system based upon particulate matter efficiency (ePM)
ISO 16890-1:2016 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 16890‑2, ISO 16890‑3 and ISO 16890‑4. The test method described in this part of ISO 16890 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 inch × 24 inch). ISO 16890 (all parts) refers to particulate air filter elements for general ventilation having an ePM1 efficiency less than or equal to 99 % when tested according to the procedures defined within ISO 16890‑1, ISO 16890‑2, ISO 16890‑3 and ISO 16890‑4. Air filter elements with a higher initial efficiency are evaluated by other applicable test methods (see ISO 29463-1, ISO 29463-2, ISO 29463-3, ISO 29463-4 and ISO 29463-5). Filter elements used in portable room-air cleaners are excluded from the scope of this part of ISO 16890. The performance results obtained in accordance with ISO 16890 (all parts) cannot by themselves be quantitatively applied to predict performance in service with regard to efficiency and lifetime. Other factors influencing performance to be taken into account are described in Annex A.

Particulate air filters for general ventilation - Determination of the filtration performance
<p>ISO/TS 21220:2009 presents test methods and specifies a test rig for measuring the filter performance of particulate air filters used for general ventilation. The test rig is designed for an air flow rate of between 0,25 m<sup>3</sup>/s<sup> </sup> [900 m<sup>3</sup>/h (530 ft<sup>3</sup>/min)] and 1,5 m<sup>3</sup>/s [5 400 m<sup>3</sup>/h (3 178 ft<sup>3</sup>/min)]. </p> <p>ISO/TS 21220:2009 is applicable to air filters having an initial efficiency of less than 99 % with respect to 0,4 µm particles. Filters in the higher end and those with an above 99 % initial efficiency are tested and classified according to other standards.</p> <p>It combines two test methods: a “fine” method for air filters in the higher efficiency range and a “coarse” method for filters of lower efficiency. In either case, a flat‑sheet media sample or media pack sample from an identical filter is conditioned (discharged) to provide information about the intensity of the electrostatic removal mechanism. After determination of its initial efficiency, the untreated filter is loaded with synthetic dust in a single step until its final test pressure drop is reached. Information on the loaded performance of the filter is then obtained. </p> <p>The performance results thus obtained cannot alone be quantitatively applied to predict in‑service performance with regard to efficiency and lifetime, so other factors influencing performance are also presented.</p>
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.
