Abstract:
A bilateral comparison between INMETRO (Brazil) and INTI (Argentina) was carried out in order to demonstrate the equivalence of calibration certificates of luminous intensity standards. Five OSRAM luminous intensity lamps were used as transfer standards. The first measurements were carried out at INMETRO and then the lamps were hand-carried to INTI for the final measurement round. It was concluded that maintained units of both national laboratories differ by less than 0.2%.
