Electrostatic attenuation test of textile electrostatic properties

The static decay time refers to the time required for the voltage on the pad sample to decay to a given percentage of its initial value. After charging the sample to 5000V, disconnect the power supply, and the voltage on the sample is attenuated by grounding, and the time required for the voltage to decay to 500V is measured.

Test device:
The electrostatic attenuation tester is composed of a high-voltage generator, a non-contact electrostatic field strength meter, a timer, a sample fixture, a metal shield and a display.

Experimental conditions:
A: The temperature is 23±3℃ and the relative humidity is 12±3%;
B: The temperature is 20±2℃, and the relative humidity is 35±5%;
C: The temperature is 23±3°C and the relative humidity is 50±5%.

Result evaluation:
Take the large value of the electrostatic decay time of the positive and negative voltage as the test result, and the result retains two significant digits, and the unit is s. If the test time exceeds 60s, it is recorded as >60s, and if it cannot be pressurized to 5000V, it is recorded as not applicable (N/A). If necessary, the electrostatic properties of textiles can be evaluated according to the following table. If there is a difference in the decay time of the positive and negative voltages, the evaluation will be made according to the result of the lower level.

The above is the detailed content of the electrostatic attenuation GB33728 test of the static electricity performance of textiles. Of course, if you want to know more about it, you are welcome to consult.
