Scope

This document specifies test methods for the determination of the breakdown voltage and withstand voltage of anodic oxidation coatings on aluminium and its alloys, on flat or near-flat surfaces and on round wire. The methods are applicable to anodic oxidation coatings used primarily as electrical insulators.
The methods are not applicable to coatings in the vicinity of cut edges, the edges of holes, or sharp changes of angle on, for example, extruded shapes.
NOTE 1 Breakdown voltage and withstand voltage are affected by relative humidity.
NOTE 2 The methods described do not give satisfactory results for unsealed coatings because they are affected by the humidity in particular.
