Paint Impact Tester
Paint Impact Tester is used for testing of coatings on metal substrates. In accordance with ISO standard, the test panel is fixed on the die using a clamping device, so that the panel surface outside the test area is not affected by the rapid deformation caused by the falling weight.
The impact Tester consists of a solid base stand with a guide tube support. The guide tube has a slot that directs a cylindrical weight that is slided up and down with the use of a collar that fits into the weight. Graduations are marked along the slot to facilitate reading where the weight is dropped. The base of the instrument includes a die support. The weights have built-in steel balls that provide
different geometrical configurations. It is important that the ball diameter fits into the die as to prevent shearing of the test samples at the inner rim of the die. In order to limit the indentation depth of the falling weight, distance rings of different thickness can be fitted. Also, different weights can be used.
