This standard applies to bonding and grounding for the prevention of ESD in an EPA. The procedures@ materials and techniques specified in this standard may not be applicable for grounding of electrical sources operating at frequencies above 400 Hz. The values and limits in ANSI/ESD S20.20 supersede any values and limits contained in this document. Purpose This standard specifies the parameters@ materials@ equipment and test procedures necessary to choose@ establish@ verify and maintain an Electrostatic Discharge (ESD) Control grounding system for use within an ESD Protected Area (EPA) for protection of ESD susceptible items.
