What is the CIE – Commission internationale de l´éclairage?

FAQ: “You used the acronym CIE.  Could you tell me what that is? If it is a document, could you please let me know where I can access it?”

CIE Commission Internationale de l´Éclairage visual CIE stands for “Commission internationale de l´éclairage” which is the French version of “International Commission on Illumination”.

The CIE is a standards body that defines and maintains the global rules for light and color measurement. This is like the CIPM (Comité international des poids et measures) who defines and maintains metric dimensions, weights and volumes. It is composed of approximately 38 member committees from countries around the world.

The CIE rules are incorporated into industrial test methods defined by approximately 30 international industrial standards bodies, the most prominent of which are:

  • ASTM – American Society of Testing and Materials, West Conshohocken, PA USA
  • ISO – International Organization for Standardization, Geneva, Switzerland.
  • JIS – Japanese Industrial Standards are available from JSA – Japanese Standards Association, Tokyo, Japan.
