How To Test Esd Floor Mats

The ansi esd association standard used in the united states to test that an esd mat is static dissipative is ansi esd s4 1 worksurfaces resistance measurement s.

How to test esd floor mats.

This requires the use of a surface resistivity esd meter to perform both resistance top to top rtt and resistance to groundable point rtg tests. The esd mat will discharge the static voltage fairly slowly to prevent the user from feeling the shock esd clothing will also to that but are also. Esd stm 97 1 floor materials and footwear voltage measurement in combination with a person visual megohmmeter test kit esd stm2 1 garments ionization test kit esd sp3 3 periodic verification of air ionizers force gage fixtures esd s1 1 wrist straps manufacturer calibration or verification unit ansi esd s20 20 using modified test. In order to certify that a highly resistive floor is ansi esd s 20 20 compliant the esd program manager must test the body voltage generation caused by the interaction between the floor the person walking across the floor and the footwear.

A conductive material embedded within the mat draws in all the static and sends it to ground earth. It occurs when an electrical charge on one non conductive surface discharges onto a conductive surface. A meter that can accurately measure into the gigohm or billion ohm range is best for testing these mats. This is usually accomplished by.

Esd mat test meter. Rtt testing for esd resistance per ansi esd s4 1. Hence the title ansi esd s4 1 worksurfaces resistance measurements. I do not test anti static mats but do test insulating mats for when we do silly things like working on live apparatus but i am looking for higher resistances than those expected for an esd mat.

For example if you shuffle your feet across a carpet particularly one that contains man made fibers a static electrical charge builds up in your body. How to choose an esd floor mat choosing an esd floor is an important step in eliminating esd damage an esd floor mat is a very important part of a static protected area. Esd mats are designed to eliminate static on its surface and of people standing upon it. Scope this test method covers the determination of electrical conductance or resistance of resilient flooring either in tile or sheet form for applications such as hospitals computer rooms clean rooms access flooring munition plants or any other environment concerning personnel generated static electricity.
