What is ISO 2376-Determination of breakdown voltage and withstand voltage about?
ISO 2376 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 the round wire.
The methods are applicable to anodic oxidation coatings used primarily as electrical insulators.
Note: 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.
Who is ISO 2376-Determination of breakdown voltage and withstand voltage for?
ISO 2376 is applicable for:
- Electrical engineers
- Electricians and people who work in the Electrical Department
- Mechanical Engineers
- Metallurgists
Why should you use ISO 2376-Determination of breakdown voltage and withstand voltage?
The electric voltage at which the current first passes through an anodic oxidation coating is measured. These breakdown voltages and withstand voltages are a function of the dielectric characteristics and the insulation properties of the anodic oxidation coatings.
ISO 2376 helps you to perform the test methods to determine the breakdown and withstand voltages of aluminium and its alloys. The test methods described in ISO 2376 help you to produce aluminium and aluminium alloy products that are more durable and resist to breakdown.
