Links between the BIPM and the CIE

  • The CIE participates in the CCU and the CCPR.
  • CIE JTC-2 Joint CCPR-CIE Task Group on "Principles Governing Photometry" has been established under the auspices of the CCPR Working Group on Strategic Planning (WG-SP).

Purpose

The CIE is devoted to worldwide cooperation and the exchange of information on all matters relating to the science and art of light and lighting, colour and vision, photobiology and image technology.

The BIPM and the CIE cooperate to ensure that data related in particular to measurements of light, optical radiation, colour, optical properties of materials, photobiological and photochemical quantities are properly based on units traceable to the SI, and to maintain consistency between the publication "Principles Governing Photometry" prepared by the CIE JTC-2 Joint CCPR-CIE Task Group and the SI Brochure.
