Full title and description

ISO 10526:2007 — CIE standard illuminants for colorimetry. Specifies CIE standard illuminant A and CIE standard illuminant D65 for use in colorimetric measurements and related colorimetry applications.

Abstract

ISO 10526:2007 defines two reference spectral power distributions used as standard illuminants in colorimetry: illuminant A (incandescent/tungsten‑filament type) and illuminant D65 (approximate average daylight). The technical content of ISO 10526:2007 was later incorporated into ISO 11664‑2:2007.

• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 17.180.20 (Color and appearance; colorimetry).
• Edition / version: Edition 1 (2007); includes Technical Corrigendum ISO 10526:2007/Cor 1:2008.
• Number of pages: 14 (approx.).

Scope

Specifies the spectral power distributions and definitions of two CIE standard illuminants used in colorimetry: illuminant A (a Planckian radiator representative of incandescent lighting) and illuminant D65 (representative of average daylight). The document provides the numerical data and usage guidance for applying these illuminants in colorimetric measurement and evaluation.

Key topics and requirements

• Definition and numerical tabulation of the CIE standard illuminant A spectral power distribution.
• Definition and numerical tabulation of the CIE standard illuminant D65 spectral power distribution.
• Guidance on the intended use of illuminant A (incandescent applications) and D65 (daylight/visual assessment).
• Technical corrigendum issued to update reference numbering (see relation to ISO 11664‑2).

Typical use and users

Used by color scientists, optical laboratories, instrument manufacturers, paint and coatings developers, textile and printing professionals, and standards bodies for calibration, color measurement, instrument specification, and colorimetric data exchange where standardized illuminants A and D65 are required.

Related standards

ISO 10526:2007 was incorporated into and superseded by ISO 11664‑2:2007 (Colorimetry — Part 2: CIE standard illuminants). Related documents include earlier ISO/CIE 10526 editions and other parts of the ISO 11664 series covering observers, tristimulus values and related colorimetry topics.

FAQ

Q: What is this standard?

A: ISO 10526:2007 is an ISO standard that defines the CIE standard illuminants A and D65 for colorimetric use; it was published in 2007 and later incorporated into ISO 11664‑2.

Q: What does it cover?

A: It provides the spectral power distributions and guidance for using the two standard illuminants (A and D65) in color measurement and related applications.

Q: Who typically uses it?

A: Color scientists, testing and calibration laboratories, instrument and lighting manufacturers, and industries requiring standardized color measurement (textiles, paints, printing, coatings, etc.).

Q: Is it current or superseded?

A: ISO 10526:2007 is withdrawn as a standalone reference and its technical content is available in ISO 11664‑2:2007 (the ISO reference number was changed via a corrigendum). Users are normally directed to ISO 11664‑2 for the current consolidated text.

Q: Is it part of a series?

A: Yes — it is part of the colorimetry-related ISO/CIE family of standards and is associated with the ISO 11664 series (Colorimetry, various parts) and earlier ISO/CIE 10526 editions.

Q: What are the key keywords?

A: CIE standard illuminants, A, D65, spectral power distribution, colorimetry, ISO 10526, ISO 11664‑2.
