IEC 60626-2:2009 provides the test methods for combined flexible materials for electrical insulation. Some properties and relevant test methods, according to the perfomance requirements of IEC 60626-3, were confirmed. Other test methods are described as a supplement of guidance for further specification that could be agreed between customer and supplier to meet specific needs of the end use. The main changes from the previous edition are as follows: some tests such as for edge tearing and stiffness, actually not used and not listed in the requirements of Part 3, were deleted.
