Fully automated instrument for measuring pendulum hardness in accordance with the König and Persoz methods.
Pendulum Hardness Test
The hardness and flexibility of a coating are opposing functionalities that need to be optimized to achieve the right balance for a specific application. A coating should have a high hardness on the one hand and be elastic at the same time. The pendulum test is used to evaluate elasticity by measuring the damping time of an oscillating pendulum. Measurement principle, test method including sample preparation and expected measurement precision are explained with typical examples from the practice.Read more
