ESD standards vary from industry to industry. This is in part due to whether or not people are required to wear ESD-protective footwear. ESD footwear inhibits charge generation and protects the wearer against potential electrical shock if the floor is too conductive. Electronics manufacturing and handling facilities, requiring ESD footwear, follow ANSI/ESD S20.20:
Resistance = < 1.0 x 10E9
Charge generation = < 100 V
In data and telecom centers, networked offices, 9-1-1- dispatch, FAA flight towers, and other end-user facilities, where people do not wear protective footwear, the floor needs to eliminate charge generation. And if people are working near energized (electrified) equipment, safety standards require resistance ranges in the dissipative (as opposed to conductive) range.
Resistance = > 1.0 x 10E6 and < 1.0 x 10E9
Charge generation = < 500 V
Our guides show you standards by industry, and which standards apply to which application.
