What to use to test whether static shoes and anti-static floors meet the standards
I would like to know the function of the ground release of the anti-static heel strap, but I don't know much about the requirements or specifications of the anti-static floor. Do you have any relevant information (in layman's terms please) on what has to be done to test the floor for compliance or what has to be done to meet compliance?
Reply: According to the relevant electrostatic standards, the ESD floor should be greater than 1x10^5 ohms and less than 1x10^9 ohms. The ESD Association has developed a standard, ESD DSTM54.1, which requires the combined resistance of the floor and footwear to be measured when measuring the footwear resistance system. This is actually a test method and does not specify or suggest resistance ranges. In order to test the actual resistance of the floor, the ANSI/ESD-S7.1 standard has a special test method using two 5-pound electrodes and driving voltages of 10 and 100 volts. The design of the AAC-TR-800 Surface Resistance Tester is well suited for this test method.
