Grounding Products

 
 

The single most important concept in the field of static control is grounding. Attaching all electrically conductive and dissipative items in the workplace to ground allows built-up electrostatic charges to equalize with ground potential. A grounded conductor cannot hold a static charge. – ANSI / ESD 6.1 ESD Association Standard for the Protection of Electrostatic Discharge Susceptible Items – Grounding.

Anti Static Mats

The “ESD Resistance” test standard for mats is ANSI / ESD S4.1 Worksurfaces – Resistance Measurements. The standard requires us to perform two types of tests: a resistance top-to-top (RTT) test, and a resistance-to-groundable point (RTG) test.

Generally, you should find the top surface of static dissipative mats measure in the lower end of the static dissipative spectrum: between 1 x 106 and 1 x 109 ohms / square.

As the ESD Association states in section 8.0 of S4.1, “these guidelines represent a range of resistance that has generally been proven to provide protection in the manufacturing environment.”

Conductive Mats and Heel Grounders

Carbon is used in products meant to electrically bond by bringing electricity to the ground immediately.

Due to its black color, most carbon-based products are discernible for the presence of black in the product.

ESD Garments

The ratio of polyester (the color of the fabric) to carbon (the black thread woven in a grid) in the smock means it is static dissipative: resisting charging when the wearer rubs the smock against itself or other objects.
