The Conical Mandrel Tester is used to determine extensibility of paint coatings on metal panels clamped in position and formed with the conical mandrel by rotating the roller frame. The panels are examined to evaluate crack resistance and detachment from the metal substrate of surfaces coated with paint under standard condition. It complies with ASTM D 522,D1737,BS 3900E11 and ISO 6860 Standards.
This instrument allows easy identification of coating failures in a single operation at a specified diameter, over part or entire mandrel length.
