Luminous intensity bilateral comparison using lamps as transfer standards between LNE (France) and INM-RO (Roumania)

Abstract : The EUROMET project 823, "Comparison of luminous intensity and luminous flux using lamps as transfer standards" between LNE (formerly BNM), France, and INM-RO, Romania, has linked the INM-RO real-ized candela to the CCPR key comparison reference values. The comparison was registered on BIPM key comparison data base with the numbers EUROMET.PR-K3.a.1. The comparison has been piloted by LNE. It has been carried out by successive calibrations of a group of four travelling standard lamps in the two laboratories. The lamps were first calibrated by INM-RO, then cal-ibrated by LNE and calibrated by INM-RO in order to check for any drift or instability. The measurements have been performed over the period November 2004 to June 2006. According to the results of the comparison, the Degree of Equivalence of the candela realized by INM-RO to the Key Comparison Reference Value of CCPR-K3 is - 0,72 % with an expended uncertainty (k = 2) of 2.14 %.
