 Tests the extensibility and adhesive qualities of laquers, paints and other protective coatings applied to a metal substrate.
A 20mm diameter steel ball punch is applied under pressure to the uncoated side of the test panel. Concentric with the punch on the coated side of the panel is a corresponding die.
As the test panel is deformed the coated surface is kept under observation and the point at which the coating cracks or becomes detached from the substrate is noted.
Max panel width 90mm, maximum thickness 1.25mm Complies with BS EN / ISO 1520 / BS 3900 : E4 Download datasheet (PDF, approx 81KB)
