ISO 105-J05:2007 provides a colorimetric method for calculating an estimate of the magnitude (and optionally the direction) of the change in the perceived colour of a textile specimen when the chromaticity of the illumination by which it is viewed is changed. It therefore provides an estimate of the colour inconstancy of the specimen.

Der vorliegende Teil der ISO 105 stellt ein farbmetrisches Verfahren zur Berechnung eines Schätzwertes für das Ausmaß (und wahlweise die Richtung) der Änderung des Farbeindrucks einer textilen Probe zur Verfügung, wenn sich Farbart und sättigung der Beleuchtung ändern, bei der betrachtet wird. Es wird folglich eine Schätzung der Farbinkonstanz der Probe bereitgestellt.
ANMERKUNG 1 Farbinkonstanz und Metamerie sind verwandt, unterscheiden sich jedoch voneinander. Hinsichtlich einer Änderung der Beleuchtungsqualität ist:
a) Farbinkonstanz das Ausmaß der Änderung des Farbeindrucks einer einzelnen Probe,
b) Metamerie das Ausmaß der Änderung der Farbdifferenz zwischen zwei Proben.
Dieser Teil der ISO 105 stellt folglich ein Verfahren bereit, zur Ermittlung von a), jedoch nicht von b).
ANMERKUNG 2 Der Vergleich der Ergebnisse dieses Verfahrens mit denen aus visuellen Bewertungen ist nur dann gültig, wenn die visuellen Bewertungen erfolgen:
a) bei Beleuchtungen derselben spektralen Energieverteilungen, wie sie bei den farbmetrischen Berechnungen verwendet werden,
b) bei Proben, die mit 1 000 lux bis 4 000 lux beleuchtet sind,
c) durch einen Prüfer, der an die bestehenden Sichtverhältnisse vollständig adaptiert ist.

Overview
EN ISO 105-J05:2007 (ISO 105-J05:2007) specifies a colorimetric method for estimating the magnitude - and optionally the direction - of the change in perceived colour of a textile specimen when the illumination chromaticity changes. Known as the CMCCON02 (Colour-Inconstancy Index) procedure, this standard provides an instrumental (spectrophotometric) approach to assess colour inconstancy (distinct from metamerism) and is widely used in textile quality control and colour management.
Key topics and technical requirements
- Purpose: calculate the CMCCON02 index to quantify how much a single specimen’s appearance shifts between a test illuminant and CIE Standard Illuminant D65.
- Measurement basis: tristimulus values (X, Y, Z) measured or computed under D65 and the agreed test illuminant using the CIE 1964 Standard Colorimetric Observer (10°).
- Chromatic adaptation: apply a simplified CAT02 chromatic adaptation transform to derive the “corresponding colour” in D65 from the test-illuminant measurements.
- Colour-difference computation: determine the colour difference between the corresponding colour (converted to D65) and the measured/computed D65 values using the formula specified in ISO 105-J03 (examples use CMC(1:1) and CIELAB).
- Numerical precision: use the specified transformation matrices to six decimal places; double-precision arithmetic recommended where necessary.
- Normalization: tristimulus values are normalized so Y = 100 for the perfect reflecting diffuser (p.r.d.) under each illuminant.
- Test reporting: clause 6 requires reporting the standard reference, specimen ID, instrument type (colorimeter/spectrophotometer and geometry), test illuminant, origin of illuminant weighting functions (e.g., ASTM E308-01), the colour-difference formula used, CMCCON02 value, and optionally ΔL*, ΔC*, ΔH*.
Applications and who uses it
- Textile manufacturers and dye houses: assess how fabrics will appear under different lighting (retail, showroom, daylight).
- Quality control and testing laboratories: provide objective, repeatable measures of colour stability to support pass/fail decisions.
- Colour scientists and formulators: evaluate dye formulations and finishing processes for lighting-dependent appearance shifts.
- Brands and retailers: predict in-store or photographic appearance consistency.
- Standards bodies and certification labs: compare instrumental results with visual assessments when lighting and adaptation conditions match the method’s assumptions.
Practical benefits include objective quantification of lighting-driven colour shifts, reproducible data for production control, and improved communication between suppliers and customers about colour performance.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 105-J05 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for

ISO 105 was previously published in 13 “parts” under the general title Textiles — Tests for colour fastness,
each designated by a letter (e.g. “Part A”), with publication dates between 1978 and 1985. Each part
contained a series of “sections”, each designated by the respective part letter and by a two-digit serial number
(e.g. “Section A01”). A complete list of these parts is given in ISO 105-A01.
