标准范围

本文件规定了测定铝及其合金、平面或近平面以及圆导线上阳极氧化涂层击穿电压和耐受电压的试验方法。这些方法适用于主要用作电绝缘体的阳极氧化涂层。这些方法不适用于切割边缘、孔边缘附近的涂层，或挤压形状上角度的急剧变化。注1:击穿电压和耐受电压受相对湿度的影响。注2:所述方法对未密封涂层的结果不令人满意，因为它们特别受湿度的影响。

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.
