| Uncertainty (mK) k=2
1 Distance from the bottom of the central well to the surface of the pure metal. 2 “Cell Only” refers to the expanded uncertainty of the cell when realized by traditional methods and maintained using traditional maintenance devices. “Simple Realization” refers to the expanded uncertainty of the cell when realized using practical methods (melting points instead of freezing points or slush ice instead of an ice mantle, for example) and maintained using Hart’s 9210 and 9260 mini cell maintenance apparatus. |
