    Significance and Use

    The most fundamental method for obtaining CIE tristimulus values or other color coordinates for describing the colors of visual display units (VDUs) is by the use of spectroradiometric data. (See CIE No. 18 and 63.) These data are used by summation together with numerical values representing the 1931 CIE Standard Observer and normalized to Km, the maximum spectral luminous efficacy function.

    The special requirements for characterizing VDUs possessing narrow or discontinuous spectra are presented and discussed. Modifications to the requirements of Practice E308 are given to correct for the unusual nature of narrow or discontinuous sources.

    1. Scope

    1.1 This test method prescribes the instrumental measurements required for characterizing the color and brightness of VDUs.

    1.2 This test method is specific in scope rather than general as to type of instrument and object.

    1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
