Scope

This standard establis es the numerical values of the esoectral relative luminous efficacy (for photopic and scotopic vis on), the colorimetric functions and the trichromatic coordinates under normal air conditions. In addition, the basic equations that link the photometric and colorimetric magnitudes with the energy flow.
