An impact test which is useful for testing paint and coating adhesion is ASTM D2794, the drop test performed on a universal impact tester (see top photo). We have two impact testers to evaluate a variety and sizes of materials – a tabletop tester shown on the left, and a 14-foot tall model. We also built a six-foot tall tester for custom testing.

Rainer Schwab, Hochschule Karlsruhe (Karlsruhe University of Applied Sciences), Germany.

Introduction to Tensile Testing / 3 Fig. 3 Components of a hydraulic universal testing machine In general, electromechanical machines are capable of a wider range of test speeds and longer crosshead displacements, whereas hy-draulic machines are more cost-effective for generating higher forces. Stress-Strain Curves

For this reason we have given particular attention to all testing methods. The EN Standards have grouped all tests on aggregates in five main subjects: Tests for general properties of aggregates. Tests for geometrical properties of aggregates. Tests for mechanical and physical properties of aggregates

Impact testing: page 3 of 13 STUDY SHEET Impact testers Impact testing When two objects collide, damage is often done to one or other of them. How well something resists damage is called its impact resistance. An impact test measures how much energy is absorbed when an object fractures or breaks under a high speed collision.

Determination of Aggregate Impact Value – Impact Test on Aggregates is done to carry out to: Determine the impact value of the road aggregates, Assess their suitability in road construction on the basis of impact value.

Matest proposes a wide range of testing equipment and high stiffness compression machines (manual, semi automatic or automatic) which allow to test concrete cubes, cylinders and blocks and satisfy the EN and other International Standards.

Aggregate abrasion value (AAV) – This test sorts out aggregates which might be strong but are not resistant to the abrasive action of vehicle tyres if used in the surface course of roads, i.e., though suitable in every other respect, they wear-out too quickly in use. In this test, 14 mm chippings are placed face-down in a rectangular mould.
