Summary:

The concept of the National Measurement System will be discussed in general, with special emphasis on color science and densitometry. Current trends in the system are a shift towards independently realizable physical standards, i.e. to collaborative efforts by industry, academia, and the National Bureau of Standards to provide a broader standards base. In densitometry, one is concerned to control and to standardize the photometric scale, wavelength scale, and geometry of illumination and viewing. This paper will address these items and concepts.
