What is BS EN 60641-1 - Pressboard and press paper for electrical purposes about?
BS EN 60641-1 is the European standard on insulating materials which is the first part of a multi-series that contains definitions related to a classification of, and the general requirements to be fulfilled by, pressboard and press paper for electrical purposes.
Who is BS EN 60641-1 - Pressboard and press paper for electrical purposes for?
BS EN 60641-1 on pressboard and press paper for electrical purposes is relevant to:
- Mechanical industry
- Insulation equipment manufacturer
- Paper industry
- Electrical industry
- Quality control personnel
- Electrical engineers
- Construction companies
Why should you use BS EN 60641-1 - Pressboard and press paper for electrical purposes?
BS EN 60641-1 gives you terms and definitions, classification, general requirements, dimensions, and conditions of supply that ensure the properties of pressboard and press paper for electrical purposes by its density, even thickness, surface smoothness, high mechanical strength, and ageing resistance.
Overall BS EN 60641-1 is benefited from adopting these best practices as they provide excellent dielectric strength and low dielectric loss, and hence pressboard and press paper are now widely accepted as the insulation pillar of the electricity industry.
What’s changed since the last update?
BS EN 60641-1:2008 supersedes EN 60641-1:1995.
The main changes with respect to EN 60641-1:1995 are listed below:
- The kind of surface finish shall no longer be specified in the standard
- Fixed nominal thicknesses have been replaced by preferred thicknesses
- Types B.6 and P.6 have been replaced, but the designations have been kept
