Note 1 to entry: Dissipative materials or objects are neither conductive nor insulating but, like conductive items, safely limit contact charging and/or dissipate even the maximum charging currents associated with their designed application when in contact with the earth.

Note 2 to entry: Boundary limits for the dissipative range for solid materials, enclosures, some objects and for bulk materials are given in IEC TS 60079-32-1, Explosive atmospheres – Part 32-1: Electrostatic hazards, guidance.

Note 3 to entry: Product standards often include specific definitions of "dissipative" which apply only to items covered by those standards and can be different to the definitions given here.
