Abstract
Following the international trend, work aimed at establishing radiometer based spectro-radio-photometric scales was undertaken at NIM Romania. New primary and secondary standards for radiant power, irradiance and spectral transmittance were developed and some results have already been obtained. Standard uncertainties levels so far obtained are of about 0.3% for radiant power and of 0.0005…0.0001 for spectral transmittance (VIS range)
