Paper Abstract

A three phase procedure is described for insuring spectrocolorimetric scale harmonization. The first phase includes the intercomparison of spectrophotometer scales of wavelength, spectral bandwidth and spectral transmittance (involving 23 laboratories). This comprehends a set of three neutral density glass filter standards and a crystal with sharp absorption bands as wavelength and spectral bandwidth standard. The second phase relates to the intercomparison of measuring procedures using product standards. The third phase addresses a real testing by the measurement of wine samples and intercomparison of results. The implementation of the procedure, results and conclusions will be described.
