Abstract :
The records of the silver- and aluminum-point blackbodies at the NMIJ/AIST since 1992 were reviewed in the features such as the plateau profile, the super cooling, the lifetime and the plateau temperature. The temperature agreement between two silver-point blackbodies was within 0.03/spl deg/C in recent three years. The temperature of two aluminum-point blackbodies agreed within 0.03/spl deg/C in recent seven years.
