Impact Testing

SKYCOAT uses the Elcometer 1615 Variable Impact Tester for evaluating the resistance of a coating to impact (elongation, cracking or peeling). Impact testing is performed according to ASTM D2794-93 (2010) standard.

There are two impact test methods: either a weight with a hemispherical punch attached falls on a coated metal sheet or a weight falls on to a hemispherical punch which is resting on the coated metal sheet.

The test specimen is fixed into position by the quick release clamp. The weight is lifted to the predetermined height and can be set by the adjustable collar device. The weight is then released and the resulting deformation is observed. The rating is determined by inches above the test specimen per weight dropped.
