Anyone know what temperature Guildline used for the oil bath of the precision resistance standards?

Hi Richard;
The temperature stability is more important then the exact temperature. But this is the exact info.
Values below 10MΩ are calibrated in flowing oil at 25C, referred to the unit of resistance as maintained by the National Research Council of Canada (NRCC) or the National Institute of Standards and Technology (NIST) and expressed as a total uncertainty with a coverage factor of k=2.  Values above 1MΩ are calibrated in air at 23C.
Cheers;
Thomas Knox
