Re: [volt-nuts] Get 10K resistor calibrated in UK
Frans: Mine which was built in 1979, and corrected for the 1990 change in the ohm, and calibrated last in 2009 has drifted upwards by 1.61 ppm total. So about 0.054 ppm/year. I don't have any data from those 30 years so this is the beginning and end points. These all seem to have a spectacular performance to say the least!

Re: [volt-nuts] Get 10K resistor calibrated in UK
Thank you, I've pinged Absolute Calibration an email asking for pricing. Question: This standard R is designed for use in a temperature stabilised oil bath. I don't have one of those. How much will this affect stability, and are there any other issues I need to worry about.

Re: [volt-nuts] Get 10K resistor calibrated in UK
Hi Dave; I do not think the resistance can be adjusted if that is what you are thinking, they will just document the actual value. But the most important thing is stability.
