Abstract
A new DC current reference standard has been developed as a component in a current calibration hierarchy in the LHC project at CERN. The standard provides 10 mA DC current with an accuracy <0.5 ppm, drift <2 ppm/year and compliance error <0.1 ppm for 0-10 V. The paper gives the results from two years evaluation of a series of 5 units.
