Understanding how ISO 16890 testing works is essential for air filter manufacturers, laboratoria, and HVAC engineers.
W odróżnieniu od starszych standardów, ISO 16890 introduces a multi-stage testing method designed to reflect real-world operating conditions and provide reliable performance data.
W tym przewodniku, we break down the ISO 16890 test method step by step.
1. Przegląd ISO 16890 Testowanie
ISO 16890 test evaluates filter performance based on its ability to remove particulate matter (PO POŁUDNIU) across different size ranges:
- PM1
- PM2,5
- PM10
The final classification (ePM1, ePM2.5, itp.) is based on average efficiency after conditioning and dust loading.
2. Step-by-Step ISO 16890 Test Process
Krok 1: Initial Efficiency Measurement
The test begins by measuring the filter’s initial fractional efficiency across a range of particle sizes.
- Uses particle counters
- Measures efficiency vs particle size curve
- Identifies baseline performance
👉 This step reflects the filter’s performance in its “new” condition.
Krok 2: Wypisać (Proces kondycjonowania)
One of the most important differences in ISO 16890 is the proces rozładowania, which removes electrostatic effects from the filter.
Why this matters:
- Many filters rely on electrostatic attraction
- Performance may drop over time in real use
👉 Discharge ensures the test reflects real-life performance, not just initial efficiency.
Krok 3: Test obciążenia pyłem
The filter is then exposed to standardized test dust to simulate real operating conditions.
During this process:
- Dust is continuously fed into the airflow
- Pressure drop increases over time
- Efficiency changes dynamically
👉 This step evaluates filter durability and stability.
Krok 4: Obliczanie wydajności końcowej
After completing the loading process, the system calculates:
- Average PM1 efficiency
- Average PM2.5 efficiency
- Average PM10 efficiency
These values determine the final classification:
- ePM1
- ePM2.5
- ePM10
- Gruboziarnisty
3. Key Parameters Measured
ISO 16890 testing focuses on several critical parameters:
Skuteczność filtracji
Measured across multiple particle sizes
Spadek ciśnienia
Indicates energy consumption impact
Zdolność zatrzymywania kurzu
Determines filter lifespan
Efficiency Stability
Wydajność po rozładowaniu i załadowaniu
4. Dlaczego ISO 16890 Testing Is More Realistic
Compared to older standards, ISO 16890 zapewnia:
✔ Real particle size evaluation (Oparte na PM)
✔ Simulation of filter aging (ładowanie pyłu)
✔ Removal of electrostatic bias (wypisać)
👉 This results in more accurate and reliable performance data.
5. Test System Requirements
To perform ISO 16890 testing accurately, a complete test rig must include:
- Stable airflow control system
- System wytwarzania aerozolu
- Particle size measurement instruments
- Zespół podawania pyłu
- Kondycjonowanie (wypisać) module
⚠️ Any instability in airflow or particle measurement will directly affect test accuracy.
6. Typowe wyzwania w ISO 16890 Testowanie
W rzeczywistości, many laboratories face issues such as:
- Unstable airflow control
- Inaccurate particle size measurement
- Słaba powtarzalność
- Inconsistent dust feeding
👉 These problems can lead to unreliable classification results.
