How often is the resistance of the anti-static table mat measured
The reason why the anti-static table mat is used to prevent electrostatic hazards is simply because its surface resistance, volume resistance, friction electrostatic voltage and electrostatic discharge time are relatively moderate, and it can be used in most occasions that need to prevent electrostatic hazards. However, due to its process and material, the anti-static table mat cannot be permanently anti-static, and its performance is always in a process of attenuation during use. In order to ensure the effectiveness of the anti-static table mat, it must be tested from time to time, so how should the testing cycle be determined?
First of all, one thing is certain. The shorter the inspection period, the more effective the anti-static table mat is guaranteed, and there are no relevant regulations, so theoretically it is best to test every day, but once the laying area or the number of tables becomes more If it is too large, it will affect the normal work of the relevant person in charge. Therefore, ordinary electronic workshops can consider testing once a month. It is best to test once a month or even a week in areas with high temperatures or frequently contaminated with various solvents or hazardous chemical warehouses. It should be noted that this is the period after the new anti-static table mat is laid. As the laying time increases, the frequency of detection should be increased accordingly. Once it is found that the resistance of the anti-static table mat does not meet the relevant requirements, it should be replaced immediately .
