Applies to cellulosic papers for electrical purposes. It specifies the methods of test to be used in testing cellulosic papers for electrical purposes to meet the requirements prescribed in the specification sheet of EN 60554-3. In this standard, reference is made in several places to ISO standards accompanied by a short description of the method used. It is to be understood that this short description is meant for identification purposes only and that all details should be taken from the ISO standard itself.
