ISO 16890 replaces EN779:2012

As of the first quarter of 2017, with a transitional period of 18 months, the standard EN779:2012 is to be replaced by ISO 16890. The ISO 16890 standard is the new global guideline.

The new test method ISO 16890 examines the subdivision on the basis of the dimensions of the particulate matter (PM), which is collected. This means that the filtration efficiency is determined on the basis of the classes PM1, PM2.5 and PM10. These classes are also used by the World Health Organization (WHO) and environmental organizations.

According to EN779: 2012, the filters are classified on the basis of their filtering efficiency at a particle size of 0.4 micron. ISO 16890 assesses the filters based on the filtering efficiency at particle sizes between 0.3 and 10 micron. This method of testing approaches the reality better, because the air pollution covers a much broader spectrum than only particles with a size of 0.4 micron.

Example:

A filter collects 65% of PM1 fine dust particles. The filter will be classified in ISO ePM1 (PM ≥50%) and the filter will be rated at ISO ePM1 65%.

Classes Efficiency Particle
ISO ePM1 ePM1, min ≥50% 0,3 ≤ x ≤ 1
ISO ePM2,5 ePM2,5 min ≥50% 0,3 ≤ x ≤ 2,5
ISO ePM10 ePM10 ≥50% 0,3 ≤ x ≤ 10
ISO coarse ePM10 ≥50%  

Comparison of EN779: 2012 and ISO 16890

 

A simple “translation” of EN779:2012 classes to ISO 16890 is not possible, because of the different measurement and assessment methods. A standard comparison table is not available. As a guide, we initially offer the following translation table:

  ISO ePM1 ISO ePM2,5 ISO ePM10 ISO coarse
G3 - - - >80%
G4 - - - >90%
M5 - - >50% -
M6 - 50% - 65% >60% -
F7 50% - 65% 65% - 80% >85% -
F8 65% - 80% >80% >90% -
F9 >80% >95% >95% -

The benefits of ISO 16890

  • A global international standard
  • ISO 16890 records the performance of the particle size in the range of 0.3 to 10 microns
  • The customer can choose their filtration requirements more precise
  • The comparison of filters from different manufacturers is much easier
