YK-9012HI
Electrostatic indenter
1. Appearance: the surface of the box shell shall be smooth and flat without scratches and permanent stains by hand and visual inspection. The surface of metal parts shall be bright and free of scratches and corrosion spots. The surface color of plastic parts shall be consistent, without crack and scratch. The operation of each functional switch shall be flexible, and the motion of halo box on the guide rail shall be stable.
2. Power supply voltage adaptability: the indentation instrument shall work normally when the AC power supply voltage changes between 198v-242v
3. Power consumption: when the indenter is powered by rated power supply voltage, the power consumption shall not be greater than 200W
4. Insulation resistance: the insulation resistance between the power input end of the indenter and the shell shall not be less than 20 m Ω
5. Electrical strength: the power input end of the indentation tester and the shell shall be able to withstand 50Hz, 1500V voltage for 1min without breakdown and flicker
6. Continuous working stability: the indenter shall work normally without failure at the rated power supply voltage for 24h
High temperature test: the indenter shall work for 2h under + 55 ℃± 2 ℃, and the sample shall work normally during and after the test
7. Low temperature test: the indenter shall work for 2h under the environment of - 10 ℃± 2 ℃, and the sample shall work normally during and after the test
8. Constant humidity heat test: the indenter shall work for 24h under the condition of 20 ℃± 5 ℃ and 90% relative humidity, and the sample shall work normally during and after the test
9. Package drop test: after the indentation instrument is packed according to the factory requirements, it is free to drop from 500mm from the vertical height to the ground, and the sample shall be free of damage after the test
10. Noise measurement: when the environmental noise of the indentation instrument is not more than 40 dB (a) and the rated power supply voltage is used, the noise at the place 1m away from the sample is not more than 70 dB (a). According to the test, the tested items of the electrostatic indentation instrument meet the requirements of the enterprise standard Q / 320217dak11-2002 electrostatic indentation instrument (enterprise standard record No. 6612-2002-n of Wuxi quality and Technical Supervision Bureau of Jiangsu Province). The product is qualified after the test It has passed the inspection of the quality supervision and Inspection Center for vehicle safety products of the Ministry of public security.
