Impact Tester

As an Authorized dealer we are engaged in providing the broad assortment of Hardness Testing equipment. Many surface coatings are subject to the risk of damage by impact. Impact testers allow reproducible conditions of impact to be defined.

The  Impact Tester has been designed to test the impact endurance of coated material, when impacted by a falling weight at specified points.  The purpose of the test is to see if test specimens can resist the effect of rapid impact testing.

The principle of the test is that a coated test specimen is impacted by a falling weight, at a fixed height; thus checking the damage or deformation of the test specimen.

Impacting test for painting and coating materials is to use an impacting head with various round angles to touch the specimen in the beginning, and then a selected weight free dropping from a certain height to hit the impacting head to impact the specimen. Running the same way to test three more specimens, and put and leave them for an hour, and then watch if there is crack on the painting.
 
The  Impact Tester can also be used on paintings with coated materials.  The same procedure is followed, using various impact heads or needles to drop freely onto the test specimen from a certain height.  This is performed three times on the same test specimen, which is then left to stand for one hour.  The test specimen is then checked for any cracking on the painting.

It is compatible with ASTM D 2794,JISK 5400,CNS 10756.

The  Impact Tester sandwiches a painted steel plate, plastics sheet, or other test piece between a spherical punch having a tip with a specified radius and a stand having a concave with the same dimensions as the tip of the punch, drops a weight onto the punch from a specified height, thus making it collide, be observed visually the conditions of the test piece and how much it is destroyed, and evaluates the impact resistance.

The  Impact Tester can also be used on paintings with coated materials.  The same procedure is followed, using various impact heads or needles to drop freely onto the test specimen from a certain height.  This is performed three times on the same test specimen, which is then left to stand for one hour.  The test specimen is then checked for any cracking on the painting.
