Overconfidence in basic ESD testing can create dangerous blind spots. Three case studies reveal how standard floor resistance tests miss critical system failures when mobile equipment loses electrical contact, exposing sensitive electronics to static damage despite apparent compliance.

A careful review of empirical research, multiple ESD standards, and return on investment provides a strong case for evaluating the installation of ESD flooring in server rooms and data centers.

A fully functional ESD floor prevents static generation and provides an effective path to ground for personnel and equipment. Many conductive and dissipative floors meet STM 7.1 resistance parameters in ANSI/ESD S20.20 but fail to provide adequate electrical contact for grounding equipment with conductive casters and drag chains.

Confusion over ESD flooring resistance terminology and requirements abounds, leaving many in the dark and creating potential risks. This article helps to clarify this complicated issue so that you can work to mitigate the problem.

Controlled environment testing of static control flooring in combination with multiple forms of ESD footwear during the qualification phase can reveal problems and is a mandatory step to avoid installing non-compliant flooring/footwear systems.
