Colorimetry - Part 1 : CIE standard colorimetric observers

This document 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.

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.

? 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.

Colorimetry - Part 1 : CIE standard colorimetric observers

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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
