Test method for static voltage index of anti-static clothing
In order to eliminate electrostatic voltage, the microelectronics industry and precision machinery production workshops require employees to wear anti-static work clothes. The index of electrostatic performance is generally an important indicator to evaluate whether the anti-static clothing is qualified, which mainly includes three parts of the test: friction voltage test, static voltage test, and resistance test. The friction voltage test has been explained last time, and today we will break down the static voltage test method:
For electrostatic voltage, electrostatic voltage test is a very important indicator of anti-static work clothes test, and detection is even more difficult. It is recommended to use electrostatic test related instruments to test, which is the most standardized, scientific, objective and The most direct way.
Various brands of electrostatic testers can be used to test electrostatic voltage, such as: ACL-350, SIMCO FMX-003 electrostatic field tester, etc. You can learn about the introduction and use of various models of electrostatic testers.
Static voltage test
This test is to verify how much the fabric itself can conduct through the conductive thread after accumulating a certain amount of static electricity in the environment and how much it remains.
Test method: Put the clothes to be tested on a special test bench, and use the probe of the electrostatic tester to read the voltage value at a distance of about 5mm.
Test standard: According to the design standard of the customer's work clothes, the most stringent can be required to be less than 50V. Generally, it is more common within 100V.
