Colorimetry - Part 1: CIE standard colorimetric observers (ISO 11664-1:2007)
ISO 11664-1:2007 comprises ISO 10527:2007 and ISO 10527:2007/Cor.1:2008. Its technical content is identical to that of ISO 10527:2007. ISO 10527:2007/Cor.1:2008 changes the reference number of the standard from 10527 to 11664-1.
ISO 11664-1:2007 specifies colour-matching functions for use in colorimetry. Two sets of colour-matching functions are specified: colour-matching functions for the CIE 1931 standard colorimetric observer and colour-matching functions for the CIE 1964 standard colorimetric observer.
Farbmetrik - Teil 1: CIE farbmetrische Normalbeobachte (ISO 11664-1:2007)
Diese Internationale Norm legt Spektralwertfunktionen zur Anwendung in der Farbmetrik fest. Es werden zwei Sätze von Spektralwertfunktionen festgelegt.
a) Spektralwertfunktionen für den Normalbeobachter CIE 1931
Dieser Satz von Spektralwertfunktionen ist repräsentativ für die Farbabgleicheigenschaften von Beobachtern mit normalem Farbsehvermögen für Gesichtsfeldgrößen von etwa 1° bis etwa 4°, bei Adaption des Auges an photopisches Sehen (Tagessehen).
b) Spektralwertfunktionen für den Normalbeobachter CIE 1964
Dieser Satz von Spektralwertfunktionen ist repräsentativ für die Farbabgleicheigenschaften von Beobachtern mit normalem Farbsehvermögen für Gesichtsfeldgrößen über etwa 4°, bei Adaption des Auges an photooptisches Sehen (Tagessehen) mit ausreichend hohem Niveau und mit einer solchen spektralen Strahlungsver¬teilung, das keine Beteiligung von Stäbchenrezeptoren der Netzhaut zu erwarten ist.
Colorimétrie - Partie 1: Observateurs CIE de référence pour la colorimétrie (ISO 11664-1:2007)
L'ISO 11664-1:2007 comprend l'ISO 10527:2007 et l'ISO 10527:2007/Cor.1:2008. Son contenu technique est identique à celui de l'ISO 10527:2007. L'ISO 10527:2007/Cor.1:2008 modifie le numéro de référence de la norme de 10527 à 11664-1.
L'ISO 11664-1:2007 définit des fonctions colorimétriques pour leur emploi en colorimétrie. Deux ensembles de fonctions colorimétriques sont définis: les fonctions colorimétriques de l'observateur CIE 1931 de référence pour la colorimétrie et les fonctions colorimétriques de l'observateur CIE 1964 de référence pour la colorimétrie.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
ISO 11664-1 was prepared as Standard CIE S 014-1/E by the International Commission on Illumination, which
has been recognized by the ISO Council as an international standardizing body. It was adopted by ISO under
a special procedure which requires approval by at least 75 % of the member bodes casting a vote, and is
published as a joint ISO/CIE edition.
The International Commission on Illumination (abbreviated as CIE from its French title) is an organization
devoted to international cooperation and exchange of information among its member countries on all matters
relating to the science and art of lighting.
ISO 11664-1 was prepared by CIE Division 2 Physical measurement of light and radiation.
ISO 11664-1 was initially published by ISO as ISO 10527:2007, and has subsequently been renumbered to be
part 1 of the ISO 11664 series.
ISO 11664 consists of the following parts, under the general title Colorimetry:
⎯ Part 1: CIE standard colorimetric observers [published previously as ISO 10527:2007, which has been
cancelled]
⎯ Part 2: CIE standard illuminants [published previously as ISO 10526:2007, which has been cancelled]

FOREWORD
Standards produced by the Commission Internationale de l’Eclairage (CIE) are a concise
documentation of data defining aspects of light and lighting, for which international harmony
requires such unique definition. CIE Standards are therefore a primary source of
internationally accepted and agreed data, which can be taken, essentially unaltered, into
universal standard systems.
This CIE Standard replaces ISO/CIE 10527:1991 and was approved by the CIE
Board of Administration and the National Committees of the CIE. This CIE Standard
has been prepared by CIE Division 2 "Physical measurement of light and radiation".
This standard contains only minor changes from the previous standard, in particular the
values in the tables of the colour matching functions and chromaticity coordinates of the CIE
1931 and 1964 standard colorimetric observers are identical with the previous standard, but it
has now been clarified that they apply for standard air.

COLORIMETRY - PART 1: CIE STANDARD COLORIMETRIC OBSERVERS
INTRODUCTION
Colours with different spectral compositions can look alike. An important function of
colorimetry is to determine whether a pair of such metameric colours will look alike. The use
of visual colorimeters for this purpose is handicapped by variations in the colour matches
made amongst observers classified as having normal colour vision. Visual colorimetry also
tends to be time-consuming. For these reasons, it has long been the practice in colorimetry to
make use of sets of colour-matching functions to calculate tristimulus values for colours:
equality of tristimulus values for a pair of colours indicates that the colour appearances of the
two colours match, when they are viewed in the same conditions by an observer for whom the
colour-matching functions apply. The use of standard sets of colour-matching functions
makes the comparison of tristimulus values obtained at different times and locations possible.
1. SCOPE
This International Standard specifies colour-matching functions for use in colorimetry. Two
sets of colour-matching functions are specified.
a) Colour-matching functions for the CIE 1931 standard colorimetric observer
This set of colour-matching functions is representative of the colour-matching properties of
observers with normal colour vision for visual field sizes of angular subtense from about 1° to
about 4°, for vision at photopic levels of adaptation.
b) Colour-matching functions for the CIE 1964 standard colorimetric observer
This set of colour-matching functions is representative of the colour-matching properties of
observers with normal colour vision for visual field sizes of angular subtense greater than
about 4°, for vision at sufficiently high photopic levels and with spectral power distributions
such that no participation of the rod receptors of the retina is to be expected.
