The air performance testing of household vacuum cleaners is primarily based on standards such as GB/T 20291.1-2021, IEC 62885-1, and IEC 60312. The specific testing requirements are as follows:

 1. Basic environmental conditions (must be controlled)

- Temperature: 23℃±2℃

- Relative humidity: 45% to 55%

- Voltage: 220V±1% (rated voltage)

II. Inhalation performance (core air index)

1. Vacuum degree (suction force) test

- Maximum vacuum degree (closed air pressure): The negative pressure value (Pa/kPa) when the suction port is fully closed

- Operating vacuum degree: negative pressure under different air volumes

- Requirement: Maximum vacuum degree deviation ≤±10%

2. Air volume test

- Unit: m³/h or L/s

- Measurement: average air volume at the suction inlet

- Requirement: Air volume deviation ≤±10%

3. Inhalation power (Airwatts, aw)

- Formula: aw = air flow (m³/s) × vacuum degree (Pa) / 100

- Requirements: Maximum suction power deviation ≤±10%; suction efficiency ≥28%

 4. Suction retention rate (under real working conditions)

- Condition: full dust bag/dust box + standard simulated dust (containing 30% quartz sand)

- Requirement: suction decay ≤20% (GB/T 20291)

5. Input power and energy efficiency

- Rated power deviation: ≤±10%

- Standby power consumption: ≤1.0W
