EN 4158:2006 (E) 4 1 Scope This standard describes a method of measurement of the electrical resistance of electrically conducting surface coatings on non-conductive parts and samples for aerospace applications.
If electrical contact areas are provided, the method is also applicable on electrical conducting layers over coated with non-conducting layers. 2 Principle The principle of the method involves applying a known voltage U to the conductive layer, measuring the c
