ESD floors do not meet ANSI/ESD S20.20. Because S20.20 is not a specification. Learn more about this process document and the standard test methods it cites.
FAQ: What does it mean when someone says a floor "meets ANSI/ESD S20.20"?
When discussing the electrical properties of their static-control floors, manufacturers usually refer to ANSI/ESD documentation, stating that their floor “meets ANSI/ESD S20.20.”
What they actually mean is that, in resistance testing, their floors measure less than 1.0 X 10E9 ohms. By itself, that fact tells only part of the story. For any floor used in a program that must meet the 2014 revision of ANSI/ESD S20.20—the flooring and flooring resistance are only one part of a bigger picture.
The floor must also meet walking body voltage (or charge generation) requirements: that is, material must generate no more than 100 volts of static on people walking on the floor, wearing whatever type of footwear is to be worn in the space.
