GB/T 4074.10-1983 《Enameled wire test method, film adhesion test----flat wire》 Related products

GB/T 4074.10-1983 "Enameled Wire Test Method Film Adhesion Test, Flat Wire" is a national standard, which stipulates the test method for the adhesion performance of flat enameled wire film. The content includes the test principle (measuring the bonding force between the film and the conductor by mechanical deformation such as winding and stretching), instruments and equipment (winding device, Tensile Testing Machine, etc.), sample preparation (intercepting the flat wire sample and processing), operation steps (controlling the degree and rate of deformation) and result evaluation (judging the adhesion performance by whether the film is cracked or flaking). This standard is suitable for mass inspection of various types of flat wire enameled wires, providing a technical basis for evaluating the anti-disbonding ability of films during processing, and helping to ensure the insulation stability and reliability of flat wires in electrical equipment.
