Section II: Applicability Range:

Transition resistance measurement for single boards or two overlapping aluminum or steel plates, with or without surface treatment, and with or without surface coating..

Three.Terminology and Definitions

a.Contact Resistance: Refers to the electrical characteristics of the contact area between two objects, which are in relative proximity and limit the flow of stable current through electrodes./Electrodes/Sheet and sheet/Contact between sheets.

b.Volume Resistance: Refers to the ohmic resistance of an electrical conductor.

c.Total Resistance: Refers to the resistance measured between two electrodes (including bulk resistance and contact resistance).

d.Set Resistance: Refers to the resistance between two electrodes without metal plates; direct contact between the two electrodes.

e.Transition Resistance: Refers to the total resistance minus the set resistance.
