Esd floor test procedure.
First published in eos esd technology aug sept 1991.
A proposed test methodology for floor materials.
Here s one proposed solution to the floor testing problem.
A static control garment has 1 x 10 11 ohms surface resistance measured point to point on the garment.
Use two 5 pound electrodes and place them on the most commonly used area of the surface.
Esd sensitive devices shall also be removed.
When used as the personnel grounding system the resistance to ground including the person footwear and floor must be less than 1 0 x 10 9 ansi esd stm97 1 and the accumulation body voltage in a standard walking voltage test ansi esd stm97 2 must be less than 100 volts.
Many of the test methods ansi esd stm7 1 and astm f150 are developed to report the characterization of esd floor materials and more importantly their performance in combination with a person wearing.
When it comes to esd flooring the test method you need to follow is ansi esd stm 7 1 2013.
Do you have a copy of this test method.
Test procedure in accordance with ansi esd s4 1 section 6 4 periodic worksurface testing.
Floors floor mats floor finishes a second method of controlling electrostatic charge on personnel is with the use of esd protective floors in conjunction with esd control footwear or footstraps.
Remove from the surface only those items that might interfere with the test.
Hopefully your goal is to identify flooring options that meet standards like ansi esd s20 20 2014.
5 reasons to put vermont slate on your esd flooring short list for 24 7 critical environments how is commercial carpet different from esd carpet testing and certification of esd floors buying esd flooring on the internet the case against overly.
The combination of floor materials and footwear provides a ground path for the dissipation of electrostatic charge thus reducing the charge.
Please note that both limits must be met.
There are several esd floor test methods associated with and recommended by voluntary associations with a keen focus on the phenomenon and control of static electricity in work environments.
To perform this test the garment should be electrically isolated laying on an insulative surface.
The minimal definition of an esd smock is that it is static dissipative.

Current flooring test procedures and the information they provide can be misleading.
