Example of use:

• Testing the scratch resistance and hardness of coatings (lacquers, paints) on test plates (metal, glass, wood, plastics)

Device configuration:

• Scratch exposure of coatings by moving a weight beam with carbide tip loaded with a defined force over the sample at constant speed by motor operation
• Score hardness corresponds to the force required to completely score the coating
• Weight bar, marked from 0 to 1500 g, with movable weight for adjusting the stress
• 4 additional weights of 1 kg each
• Scribing needle with ball point made of tungsten carbide with Æ 1 mm, scribing knife according to Clemens with tungsten carbide cutting edge, pen with rubber coating
