Detailed Description
 


Automatic-counting Pendulum Hardness Tester
Pendulum Hardness Tester
viscoelastic behavior of the coating determine hardness

       This method evaluates hardness by measuring the damping time of an oscillating pendulum. The pendulum rests with 2 stainless steel balls on the coating surface. A physical relationship exists between oscillation time, amplitude and the geometric dimensions of the pendulum. The viscoelastic behavior of the coating determines its hardness.

      When the pendulum is set into motion, the balls roll on the surface and put pressure on the coating. Depending on the elasticity, the damping will be stronger or weaker. If there are no elastic force, the pendulum will damp stronger. High elasticity will cause weak damp stronger. High elasticity will cause weak damping.

     The hardness will be described as the ratio of the necessary time for the pendulum swinging within the stated swing amplitude on the paint film and the necessary time for the pendulum swinging within the same swing amplitude on the glass board. It is designed and manufactured in according with ISO 1552 ,GB/T 1730-93 to Measure the hardness of the film of painting and coatings.
