| Product Name | Vacuum Cleaner | Model | GHA-508, 220V, 50Hz |
| No. | Test Item | Standards & Technical Requirements | Result |
| 1 | Appearance | The surface shall be smooth and clean, free of burrs, shrinkage holes, cracks, deformation and other abnormalities with uniform color; the metal plating shall be free of corrosion, scratches, and other defects. | Pass |
| 2 | Marking | Full name of manufacturer, product name, motor model and production date shall be marked. | Pass |
| 3 | Temperature | Operate under 1.06 times rated voltage and normal load until temperature rise stabilizes. | ≤70K |
| 4 | Protection against access to live parts | Within 1 second after power cut, measure the voltage of plug pins with an instrument that does not significantly affect measured values. Voltage shall not exceed 34V. Rated capacitance shall not exceed 0.1μF. | 0.4V |
| 5 | Noise | Test in a semi-anechoic chamber with floor brush and hose connected under rated voltage and normal load; measuring distance: 1.3m from product to noise meter. Product noise ≤70dB. | ≤70 dB |
| 6 | Input Power | Power measured after running for 3 minutes with hose connected under rated voltage, within ±15% of rated power. | — |
| 7 | Maximum Vacuum Degree | Under rated voltage with hose connected and suction inlet blocked, maximum vacuum degree ≥15000Pa (600W/HS). | 17KPa |
| 8 | Dielectric Strength | Apply 3750V/min, 5mA between metallic and non-metallic parts. No breakdown shall occur; functions remain normal after test. | Pass |
| 9 | Insulation Resistance | Run the product for a period, unplug it, and measure insulation resistance ≥7MΩ. | Pass |
| 10 | Endurance Test | Run at 1.06 times rated voltage for 14 minutes, then power off for 30 seconds; subsequently run for 10 hours under normal load, then run for another 10 hours under 0.85 times rated voltage. Operation cycles can be continuous or divided, but each cycle shall not be less than 8 hours. | Vacuum cleaner endurance ≥300h |
| 11 | Power Cord Pull Test | Pull out the full power cord, hang a weight under the cord, test duration: 1 minute, move up and down 25 times. 1~4kg/60N; displacement of pulled power cord ＜2mm. | Pass |
| 12 | Switch Life Test | Operate under rated voltage; one cycle = ON-OFF, total cycles: 10,000 times. No spark or switch malfunction during test. | Pass |
| 13 | Dust Tank Capacity | 10L | 10L |
