摘要

During 1984-86 and during 1997/98 the NML realized the candela and lumen and used the newly realized scales as basis for participation in an international intercomparison. The luminous intensity standards (six lamps of the type Wj41/G) were measured through a V(λ) filter by means of a room temperature absolute radiometer. The luminous flux standards (six 200 W GEC luminous flux lamps) were measured on a goniophotometer by spatially integrating the illuminance distribution around the lamps. The photometer head of the goniophotometer was calibrated for illuminance by means of luminous intensity standards measured with the absolute radiometer. The purpose of this paper is to present the results of the candela and lumen realization done at the NML in 1997/98 and to compare these to the 1984-86 realization of these units at NML, and to discuss certain problems encountered during the measurement.
