Abstract :
The design and performance of six 10-k Omega standard resistors fitted in thermoregulated enclosures are described. A potentiometric resistance comparator was used to compare the six resistors among themselves. The resistance values, known in terms of a quantized Hall resistance standard, were found to drift at constant rates ranging from six to 64 parts in 10/sup 9/ per year. The results show that the resistance values can be predicted, over periods of months, to one part in 10/sup 8/.<>
