How often is the resistance value of the anti-static table mat measured?
The reason why anti-static table mats are used to prevent electrostatic hazards is simply because of their moderate surface resistance, volume resistance, frictional electrostatic voltage, and static discharge time. They can be used in most occasions where electrostatic hazards need to be prevented. However, due to its craftsmanship and materials, the anti-static table mat cannot be permanently anti-static, and its performance is always in a process of decay during use. In order to ensure the effectiveness of the anti-static table mat, it must be tested frequently, so how should the detection cycle be determined?
First of all, one thing is certain, the shorter the detection period, the more effective the anti-static mat can be guaranteed, and there are no relevant regulations, so in theory it is best to test every day, but once the area laid or the number of countertops becomes relatively large 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. Areas with high temperature or often contaminated with various solvents or hazardous chemical warehouses are best tested once every half a month or even a week. 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 also increase accordingly. Once the resistance of the anti-static table mat is found not to meet the relevant requirements, it should be replaced immediately. .
