Oddly enough there is no traceable definition of RMS voltage. The only way that NPL/PTB/NIST etc do it is using a thermal transfer standard. Because DC voltage is defined in terms of the Josephson effect to umpteen places of decimals, you compare the heating effect of the AC voltage being calibrated with the heating effect of a DC voltage derived from the Josephson standard.
