ESD TILES Flooring

Electrostatic Discharge ESD flooring protects electronics from damage caused by static electricity which accumulates as people walk Conductive elements such as carbon graphite or metalcoated particles distributed throughout the flooring material give ESD floors electrical conductivity and create an electrical pathway from the walking surface to ground

ESD flooring standards are based on an ESD flooringfootwear combination Some but not all ESD floors also prevent charge generation  ie static from accumulating as people walk Thus its critical to determine the type of footwear people will use in the space When choosing an ESD floor always test for both electrical resistance STM71 and charge generation STM972

A floor can be conductive and still generate enough static to damage electronics

To be sure you choose the right ESD floor for your application always evaluate

The relevant electrical code

Industry standards for electrical resistance and charge generation body voltage

Independent test results resistance STM71 charge generation STM972

Footwear used in the space ESDprotective footwear or regular street shoes

Any specific requirements for the application

The demands and constraints of the environment

Buyer goals and objectives

A static discharge as small as 20 volts can damage or destroy microelectronics

Staticcontrol floors create a traceable path from the walking surface to ground

To measure the resistance of a flooring material we use test method ANSI STM71

ANSIESD S2020 requires electrical resistance to measure below 1x 10E9 ohms

Motorola R56 and FAA 019f require 1 x 10E6 ohms and below 1 x 10E9 ohms

If people wear street shoes in the space the floor must also prevent charge generation

An ESD floor can be conductive and still generate static fail to prevent body voltage

To evaluate the potential for charge generation use ANSI STM972
