Colorimetry - Part 2 : CIE standard illuminants

This document defines three CIE standard illuminants for use in colorimetry: CIE standard illuminant A for the representation of typical tungsten-filament lighting, CIE standard illuminant D65 for the representation of average daylight having a correlated colour temperature of approximately 6 500 K and CIE standard illuminant D50 for the representation of daylight with a correlated colour temperature of approximately 5 000 K. Values of the relative spectral power distribution of the three illuminants are included in this document.

Colorimetry - Part 2 : CIE standard illuminants

ISO 11664-2:2007 comprises ISO 10526:2007 and ISO 10526:2007/Cor.1:2008. Its technical content is identical to that of ISO 10526:2007. ISO 10526:2007/Cor.1:2008 changes the reference number of the standard from 10526 to 11664-2. ISO 11664-2:2007 specifies two illuminants for use in colorimetry. The illuminants are the CIE standard illuminant A and the CIE standard illuminant D65.

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.
