it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version

DISCUSSION—
The forword of EIA-541 states, “'Antistatic’ no longer refers to a resistivity range . 'Antistatic’ refers to a material’s ability to resist triboelectric charge
generation. A material’s antistatic propensity depends upon the nature of the material itself and the material with which it is in contact along with the
means of surface separation. The antistatic property is not a dependent function of material resistivity. Material resistivity is an intrinsic property used
to define its degree of conductivity without regard to other materials.”
conductor—a substance or body that allows a flow of electric current to pass continuously along it or through it when a sufficient
voltage is applied across any two points.
dielectric breakdown—a threshold effect in a dielectric medium where, at some electric field strength across the medium, bound
electrons become unbound and travel through the medium as a current. In solid media, the region of the current path is
permanently damaged. The unit of measurement is usually volts per unit of thickness.
electrically continuous surface—a surface that is electrically conductive in that current can be passed at an applied voltage
between any two points of its physical surface.
electrical overstress (EOS)—overstress which may be due to ESD or the operation of items beyond their electrical specifications.
electromagnetic shield—a screen or other housing placed around a device or circuit to reduce the effects on them from both
electric and magnetic fields.
electrostatic discharge—the transfer of electrostatic charge between bodies at different electrostatic potentials.
electrostatic discharge (ESD) protective— a property of materials capable of one or more of the following:
preventing the generation of static electricity.
