Functional evaluation of Class F systems

The concept of functional testing of materials in combination in systems and its value beyond simple material property tests has been widely accepted by the electrical industry and the insulation materials suppliers, The accelerated interest in insulation systems and in the testing of systems is shown by the tremendous increase in published articles and magazine and technical journal coverage of all phases of electrical insulation in the last ten years as well as the highly successful technical sessions of this conference in its short life since the first meeting in Cleveland in 1958.
