Anti-static rubber mat detection method
Anti-static rubber mat detection method: Test tool: surface resistance tester 1. Surface resistance test instrument to detect anti-static rubber method:
The surface resistance tester is an instrument for testing the surface resistivity of an object, which can be tested for simple and repeatable conductivity, surface resistance, and insulation surface properties. The test range is 10 to the power of 3 to 10 to the 12th power, 10 to the 3rd power - 10 to the 5th power is the conductive range, and the green light shows: 10 to the 6th power - 10 to the 11th power is anti- ) Static range, yellow light display; 10 to the 12th power is the insulation range, red display.
The effective range of anti-static rubber mat is: anti-static rubber surface resistance (green layer resistance) is 10 from the power of 6 to 10, the anti-static layer between the 9th power; anti-static rubber back resistance (black resistance) is 10 3 The fifth power of the power -10 is a conductive layer.
During the use of anti-static rubber mat, the surface resistance test instrument is often placed on the surface of the anti-static rubber and then the button of the surface test instrument is pressed.
When the surface resistance instrument is displayed as a yellow light, the anti-static rubber is effective. When the light is red or green, the anti-static rubber is invalid; the same method is used to test the back of the anti-static rubber. When the light is green, The anti-static rubber is effective. When the light is yellow or red, the anti-static rubber is invalid. When the anti-static rubber surface resistance and the back resistance are both up to standard, when the surface resistance and the back resistance are not up to standard or At the same time, failure to meet the standard is invalid.
