How to test the resistance of anti-static shoes
Anti-static shoes are protective shoes with anti-static effect. They are widely used in industrial production. However, not all anti-static shoes are qualified anti-static shoes, and qualified anti-static shoes are guarantee workshops. The basic guarantee of internal anti-static safety, the resistance value of qualified anti-static shoes should be between 10 6th power ohm and 10 9th power ohm. Today, I will share with you how to test the resistance of anti-static shoes.
The resistance test of anti-static shoes is very strict. You should first prepare a variety of test instruments, auxiliary supplies, and of course the indispensable anti-static shoes. The anti-static shoes used for testing can not be tested by just using them. Before testing, anti-static shoes need to be treated with alcohol, distilled water, etc., and qualified test conditions are required. For example, the test environment requires 20 ℃ ± 2 ℃, and the relative humidity is within the range of 30% ± 3% to ensure The accuracy of the measurement results is not interfered by other factors.
During the test, fill the anti-static shoes with steel balls as required, place the test sample of the installed steel balls on the specified external electrode, connect the specified DC power supply between the internal and external electrodes for 1 min, and then turn the current Record the value and voltage value.
