| RPT |
All materials become a solid state from a liquid state through some action (heat, light, time and others), and produce various physical properties. The change of phase from liquid to solid causes various problems. Due to this fact, there are cases that the expected performance design cannot be achieved and the performance of the material is lowered and changed by some environmental factor in the process. The most important evaluation item among the material evaluations is to pursue the aging change of the chemical-physical performances in the process of curing and drying from a liquid state to a solid state.
The instrument developed for this evaluation purpose is a rigid-body pendulum type physical properties testing machine, model RPT-3000W. |

| Available to Evaluate Materials in Versatile Fields |
| With this instrument, one can evaluate the curing and drying process of organic high polymeric materials, and their bulk physical properties, or evaluate the surface's physical properties and other materials, such as inorganic material like concrete, cosmetics, paper and foods in the operational temperature range from -100 degrees Celsius to 400 degrees Celsius. |

| -MEASUREMENT- |
Fix the test piece coating plate on the cooling/heating block. Set the pendulum so that the knife-edge, the fulcrum of the swing,
comes vertically into contact on the test piece coated surface. Apply free vibration to the pendulum. For measurement of physical properties, use a cylindrical edge. By analyzing this vibration, the curing process and surface's physical properties can be evaluated. |
