| Group | Class | Loss of final charge Pa | Average performance (Am) against systhetic dust % | Average efficiency(Em) against particles of 0,4 ɲm % | Minimum* efficiency against particles of 0,4 ɲm % |
|---|---|---|---|---|---|
| Thick | G1 | 250 | 50 ≤ Am < 65 | – | – |
| G2 | 250 | 65 ≤ Am <80 | – | – | |
| G3 | 250 | 80 ≤ Am <90 | – | – | |
| G4 | 250 | 90 ≤ Am | – | – | |
| Medium | M5 | 450 | – | 40 ≤Em < 60 | |
| M6 | 450 | – | 60 ≤Em <80 | ||
| Fine | F7 | 450 | – | 80 ≤Em <90 | 35 |
| F8 | 450 | – | 90 ≤Em <95 | 55 | |
| F9 | 450 | – | 95 ≤Em | 70 |
* ª Minimum efficiency is the lowest efficiency between the efficiency after the discharge, the initial efficiency and the lowest efficiency throughout the charge trial procedure
