ISO 2376-2019 鋁及鋁合金陽(yáng)極氧化--擊穿電壓和耐壓的測定 Anodizing of aluminium and its alloys — Determination of breakdown voltage and withstand voltage

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.rd edition 2019-03 Anodizing of aluminium and its alloys — Determination of breakdown voltage and withstand voltage Anodisation de l'aluminium et de ses alliages — Détermination de la tension de claquage et de la tension de tenue Reference number ISO 2376:2019(E) ？ ISO 2019 ISO 2376:2019(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 2019 All rights reserved.
