22、on or networking permitted without license from IHS-,-,-vFOREWORD Standards produced by the Commission Internationale de lEclairage (CIE) are a concise documentation of data defining aspects of light and lighting, for which international harmony requires such unique definition. CIE Standards are the

23、refore a primary source of internationally accepted and agreed data, which can be taken, essentially unaltered, into universal standard systems. This CIE Standard replaces ISO 10526:1999/CIE S005:1998 and was approved by the CIE Board of Administration and the National Committees of the CIE. It cont

24、ains only minor changes from the previous standard, which was prepared by CIE Technical Committee 2-33, “Reformulation of CIE Standard Illuminants A and D65“ *). The numerical values of the relative spectral distributions of standard illuminants A and D65 defined by this Standard are the same, withi

25、n an accuracy of six significant digits, as those defined in earlier versions of these illuminants. TABLE OF CONTENTS FOREWORD v 1. SCOPE 1 2. NORMATIVE REFERENCES 2 3. DEFINITIONS 2 4.

SCOPE This Internationa

30、l Standard specifies two illuminants for use in colorimetry. The illuminants, which are defined in clauses 4 and 5 of this International Standard, are as follows: a) CIE standard illuminant A This is intended to represent typical, domestic, tungsten-filament lighting. Its relative spectral power dis

31、tribution is that of a Planckian radiator at a temperature of approximately 2 856 K. CIE standard illuminant A should be used in all applications of colorimetry involving the use of incandescent lighting, unless there are specific reasons for using a different illuminant. b) CIE standard illuminant

32、D65 This is intended to represent average daylight and has a correlated colour temperature of approximately 6 500 K. CIE standard illuminant D65 should be used in all colorimetric calculations requiring representative daylight, unless there are specific reasons for using a different illuminant. Vari

33、ations in the relative spectral power distribution of daylight are known to occur, particularly in the ultraviolet spectral region, as a function of season, time of day, and geographic location. However, CIE standard illuminant D65 should be used pending the availability of additional information on

34、 these variations. Values for the relative spectral power distribution of CIE standard illuminants A and D65 are given in Table 1 of this International Standard. Values are given at 1 nm intervals from 300 nm to 830 nm. The term “illuminant“ refers to a defined spectral power distribution, not neces

35、sarily realizable or provided by an artificial source. Illuminants are used in colorimetry to compute the tristimulus values of reflected or transmitted object colours under specified conditions of illumination. The CIE has also defined illuminant C and other illuminants D. These illuminants are des

36、cribed in Publication CIE 15:2004 but they do not have the status of primary CIE standards accorded to the CIE standard illuminants A and D65 described in this International Standard. It is recommended that one of the two CIE standard illuminants defined in this International Standard be used wherev

37、er possible. This will greatly facilitate the comparison of published results. It is noted that in the fields of graphic arts and photography extensive use is also made of CIE illuminant D50. In most practical applications of colorimetry, it is sufficient to use the values of CIE standard illuminant

38、s A and D65 at less frequent wavelength intervals or in a narrower spectral region than defined in this Standard. Data and guidelines that facilitate such practice are provided in Publication CIE 15:2004, together with other recommended procedures for practical colorimetry. The term “source“ refers

39、to a physical emitter of light, such as a lamp or the sky. In certain cases, the CIE recommends laboratory sources that approximate the spectral power distributions of CIE illuminants. In all cases, however, the definition of a CIE recommended source is secondary to the definition of the correspondi

40、ng CIE illuminant, because of the possibility that, from time to time, new developments will lead to improved sources that represent a particular illuminant more accurately or are more suitable for laboratory use. Subclause 6.1 of this International Standard describes CIE source A, which is recommen

41、ded for laboratory realizations of CIE standard illuminant A. At present, there is no CIE recommended source representing CIE standard illuminant D65. 1BS EN ISO 11664-2:2011EN ISO 11664-2:2011 (E)Copyright European Committee for Standardization Provided by IHS under license with CENNot for ResaleNo
