Test standards and test procedures for antistatic gloves
Anti-static gloves are made of special anti-static gloves. The materials used are nylon and conductive fibers. The distance between the fibers is 4mm. It has strong elasticity and anti-static properties. It avoids static electricity generated by the human body. Cause damage and can be used in a clean room.
For antistatic gloves, test methods and test standards are very important. A lot of equipment will be used during the test. There are two categories of megohmmeters for testing, 100V and 10V (±5%), of which 100V is used to test ≧1X106 ohms and 10V is used to test <1X106 ohms. At the same time, you need an anti-static wrist strap, a metal plate, and a static voltmeter.
The test must be carried out according to certain procedures. The specific procedures are as follows:
1. The temperature and humidity conditions at the time of inspection are: temperature: 23±3oC, relative humidity: 40%-60%±5%.
2. Check whether the device under test and the megger electrode can be hygienic. If necessary, clean it with a soft cloth dampened with 70% isopropyl alcohol.
3. At the time of the first inspection and inspection, at least six product samples are required to be tested.
4. Check the external resistance of the glove. Place the sample to be tested on the insulation board, and then place the electrode of the megohmmeter on the outer surface of the glove. The electrode does not exceed the sample.
5. After the electrode is placed, when testing the anti-static gloves, use the 10V file of the megohmmeter to check. If the reading is <1.0X107 ohm, use this file to continue the inspection. If the reading is >1.0X107 ohm, use the 100V file for inspection. . After the reading is stable, record the reading and check it.
6. Use the same phase to investigate other samples. Specification of external resistance: ≥1.0X105 ohms to <1.0X109 ohms
For anti-static gloves, accurate data can only be measured by testing in strict accordance with the test procedure. Only to avoid the harm to electronic products and chips in the work process.
