Abstract
The reliability on the fixed point of Palladium was evaluated by examination using the crucible and wire methods. As the results, the temperature of the fixed point was proved to be independant of realizable technique with the methods, but remarkably depends on an internal atmosphere, especially the effect of Oxygen in air, surrounding two samples (ingot or wire) for the fixed point. It is found that the temperature of the fixed point in argon is 1.7°C higher than that of the fixed point in air.
