Universal Impact Testing – ASTM D2794

Impact Strength Testing Instruments. Electronics and Electrical Testing Equipments. Air Permeability Testing Instruments. Useful for checking axtm to impact surface damage and penetration for construction materials viz plastic, ASTM D provides a procedure for rapidly deforming by impact a coating film and its substrate and for evaluating the effect of such a deformation.

Lightly place the weight on the indenter and adjust the guide tube so that the lifting pin is at the zero mark. We also built a six-foot tall tester for custom testing. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine s2794-93 applicability of regulatory limitations prior to use.

By gradually increasing the distance the weight drops, generally 1 inch 25 mm at a time, the point at which failure usually occurs can be determined. NOTE 4—Because of the poor reproducibility of this method, the reporting of inch-pounds ast in comparing coatings for impact resistance should be restricted to one laboratory.

Impact Resistance Ashm For Paint: We have two impact testers to evaluate a variety and sizes of materials — a tabletop tester shown on the left, and a foot tall model.

In its use over many years, this test method for impact resistance has been found to be useful in predicting d294-93 performance of organic coatings for their ability to resist cracking caused by impacts.
