In an effort to develop a Standard Reference Material (SRM™) for Seebeck coefficient, we have conducted round-robin measurement survey of two candidate materials-undoped Bi 2 Te 3 and Constantan (55 % Cu 45 Ni alloy).Measurements were performed in rounds by twelve laboratories involved active thermoelectric research using number different commercial custom-built systems techniques.In this paper report the detailed statistical analyses on interlaboratory results methodology analysis irregularly sampled curves study setting.Based these results, selected as prototype standard material.Once available, SRM will be useful future data comparison instrument calibrations.
