英文名称：Anodizing of aluminium and its alloys — Determination of breakdown voltage and withstand voltage
发布日期：2019-03
标准范围
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.
