What is BS EN 60626-2 – Electrical insulation materials test about?
BS EN 60626-2 provides the test methods for combined flexible materials for electrical insulation. Some properties and relevant test methods, according to the performance requirements of IEC 60626-3, were confirmed.
Other test methods are described as a supplement of guidance in BS EN 60626-2 for further specification that could be agreed upon between customer and supplier to meet specific needs of the end-use.
BS EN 60626-2 deals with test methods of combined flexible materials consisting of two or more different insulating materials laminated together as described in IEC 606261. The components of flexible combined materials are polymer film and fibrous sheet material. This standard does not include materials based on mica paper, as primary component, covered by IEC 60371, but mica paper may be used as complementary material.

BS EN 60626-2 on electrical insulation materials test is useful for:
- Electrical engineer
- Manufacturer of heavy electrical equipment
- Manufacturer of electrical appliances
- Power Distribution companies
- Electrical insulating material manufacturer
- Electrical wire manufacturer
Why should you use BS EN 60626-2 - Electrical insulation materials test?
BS EN 60626-2 provides best practice guidelines for testing various characteristics of combines flexible electrical insulation materials, such as:
- Thickness
- Weight per unit area or grammage
- Tensile strength
- Effect of heat
- Electric strength
BS EN 60626-2 can help in better communication between supplier and the customer, to be able to select appropriate material for further processes in manufacturing.
What’s changed since the last update?
BS EN 60626-2:2009 supersedes EN 60626-2:1995.
The main changes from EN 60626-2:1995 are as follows:
Some tests such as for edge tearing and stiffness, not used and not listed in the requirements of Part 3, they were deleted.
