The Conical Mandrel Bend Tester, model BGD 566, is designed to assess the extensibility of paint coatings on metal panels. These panels are clamped in position and formed around the conical mandrel by rotating the roller frame. The test evaluates crack resistance and detachment of the coated surface from the metal substrate under standard conditions. The instrument adheres to ASTM D 522, D1737, BS 3900E11, and ISO 6860 Standards.
It allows for easy identification of coating failure in a single operation at specified diameters over part or the entire mandrel length.

Technical Specification
The panels are examined to evaluate crack resistance and detachment from the metal substrate of coated surface which is coated with paint under standard conditions.
This instrument allows easy identification in a single operation the coating failure at specified diameter, over part or entire mandrel length.
Main Technical Parameters
Diameter range: Ø3.1 - 38mm ±0.1mm (0.12 - 15")
Length: 203 ±0.3 mm (8")
The new clamping device allows faster and more convenient fixing of samples
