scope:
This document provides a test method that measures the charge dissipation characteristics of worksurfaces. To accomplish this, a conductive test object is charged, placed on the worksurface under test, and then removed. The resultant charge on the test object is an indicator of the ability of the tested worksurface to dissipate charge from the test object placed on it. This is only applicable however for the test object specified within this document. This standard test method is designed for use in a laboratory environment for qualification, evaluation or acceptance of worksurfaces and not for periodic testing.
Purpose
The purpose of this standard test method is to aid in determining the ability of ESD protective worksurfaces to dissipate charge from a conductive test object placed on them. This ability may not be revealed through standard resistance measurements as outlined in ANSI/ESD S4.1.
