A good reference is the old Fluke publication "Calibration -
Philosophy in Practice"
by Steve Spang. (1975)

Be very carefull with standard cells! Never load a cell. Use the cells
only with
high ohm null detectors.
A loaded cell need a long time for regeneration (or come back never to
the old value!)

I think a good zener reference is a better practical solution for today.
