A configurable platform for ISO 16890 testing, including fractional-efficiency measurement, airflow resistance, filter conditioning and dust-loading evaluation. The main test duct, IPA conditioning cabinet and dust-loading system are separate functional modules coordinated through the laboratory workflow.
| Airflow | 300–5400 m³/h |
|---|---|
| ΔP range | 0–800 Pa |
| Particle counter | TSI 3330 OPS (0.3–10 µm) |
| Aerosol | DEHS / KCl |
| Dust feeder | SC-189 (A2/A4/ASHRAE dust) |
| Filter size | ≤610×610 mm; Ø ≤400 mm; length ≤1100 mm |
| Footprint | approx. 15×3×3 m |

| Fractional Efficiency and Resistance | ISO 16890-2 measures upstream and downstream particle concentrations across the required particle-size range together with filter airflow resistance. |
| Filter Conditioning | ISO 16890-4 uses a controlled IPA-vapour procedure to reduce the influence of removable electrostatic charge and determine minimum fractional test efficiency. It should not be described as completely eliminating all electrostatic effects or simulating a fixed period of field ageing. |
| Dust Loading | ISO 16890-3 evaluates gravimetric efficiency and airflow resistance versus captured test-dust mass. Dust loading provides separate performance data and does not determine the ISO ePM classification. |
