IEC 60312-2: Vacuum Cleaner Performance Measurement — Where Does a 500W Suction Power Rating Come From?
Suction Power vs. Motor Power: The Standardized Test Behind Every Vacuum Rating
IEC 60312-2:2010 specifies household vacuum cleaner performance measurement methods. Every “suction power” and “energy efficiency” rating on a vacuum nameplate derives from this standard.
| Parameter | Method | Unit | Meaning |
|---|---|---|---|
| Air Power | Airflow × static pressure at nozzle | W | “How hard it sucks” |
| Dust Pickup | % of standard dust removed from standard test carpet | % | Actual cleaning ability |
| Filtration Efficiency | Exhaust particle concentration (0.3–10 μm) | % | Critical for allergy/asthma users |
The gap between “2,000W motor power” and “500W suction power” represents losses: motor efficiency + airflow resistance + filtration system back-pressure. EU Regulation 666/2013 capped motor power at 900W, forcing manufacturers to improve air-path and filtration efficiency rather than simply fitting bigger motors.
TNLab — “Air power” measures real cleaning ability. “Motor power” only tells you how much electricity it consumes.
