The spectral radiance of transfer standard-deuterium lamp is calibrated using Hefei 800 MeV electron storage ring synchrotron radiation (HESYR) as an absolute UV-VUV spectral radiometric standard. The data processing and uncertainty analysis method of PTB is employed, in 115～300 nm the spectral radiance values of two deuterium lamps are obtained, and the overall uncertainty for D2 lamp calibration is 12.1%. A detailed analysis of the contributions to this uncertainty points out that the major part is caused by the uncertainty of the polarization properties of the radiometric instrumentation. In the range of 164～300 nm the D2 lamp absolute spectral radiant distribution obtained using HESYR China and that derived from BESSYⅡGermany have a discrepancy within ±20%. They are consistent within the given uncertainties.
