CIE Research Strategy Launched: The CIE has developed a list of topics which require investment and research to ensure that current and future technologies that involve or incorporate light and lighting are supported by accurate and up-to-date information. The list of the top priority CIE research topics can be found at the “Research Strategy” link at the top of  this home page or at this URL, http://www.cie.co.at/index.php/Research+Strategy .

CIE Tutorial and 4th CIE Symposium on Colour and Visual Appearance, September 5 to 7, 2016,  Prague, Czech Republic. This will be followed by Technical Committee Meetings on September 8 and the Division 1 Annual Meeting on September 9.


Characterization of the Performance of Illuminance Meters and Luminance Meters

Joint ISO/CIE International Standard

 

ISO/CIE 19476:2014(E) (former CIE S 023/E:2013)

 

This joint ISO/CIE International Standard is replacing CIE International Standard CIE S 023/E:2013 without modification of its technical content.
The standard defines quality indices characterizing the performance of illuminance and luminance meters in a general lighting measurement situation, as well as measurement procedures for the individual indices and standard calibration conditions.
Measurements of illuminance or luminance and their accuracy are influenced by various parameters, such as operational conditions, properties of light sources, as well as characteristics of the applied photometers. The characteristics of these photometers alone do not allow the determination of the measurement uncertainty for a specific measurement task. Nevertheless, it is generally true that instruments with “better” characteristics in most cases produce smaller uncertainties than instruments with “worse” properties. This standard has been written to:
• give clear and unambiguous definitions for the individual quality indices;
• define measurement procedures and methods for numerical evaluation of these quality indices;
• define calibration conditions for illuminance meters and luminance meters.
Where different, the definitions of the quality indices and the associated measurement procedures and methods for numerical evaluation given in this standard supersede those given in CIE Publication 53-1982. CIE publication 69-1987 has been superseded by this standard.
This ISO/CIE International Standard has been approved by the CIE National Committees and by ISO. It is readily available at the National Committees of the CIE or via the CIE Webshop.
