Some calibration standards are fixed devices with a single nominal value. Examples are DC voltage sources, standard resistors and so on. When calibrated, the report should include the measured value and the calibration uncertainty.
There are several methods of determining the reference value to be used (the "assigned value"). I need to develop a defined process for my lab, but first I would like to benchmark what others are doing.
The poll lists a number of different ways I can think of, and I am interested in other ways that may be used. Also, of course, the method may vary based on the nature of the device.
It would also be interesting to discuss the good and bad points of various methods.
(I hope this works - it's my first attempt at a poll!)

But hey, I'm headed back to England at the end of the week for
