Full title and description

ISO 105-J05:2007 — Textiles — Tests for colour fastness — Part J05: Method for the instrumental assessment of the colour inconstancy of a specimen with change in illuminant (CMCCON02). This part of ISO 105 defines a colorimetric (instrumental) procedure to estimate the magnitude — and optionally the direction — of the perceived colour change of a textile specimen when the chromaticity of the viewing illumination is changed.

Abstract

ISO 105-J05:2007 provides a colorimetric method (designated CMCCON02) for calculating an estimate of the size of the change in perceived colour of a textile specimen caused by a change in illuminant chromaticity; the method can also indicate the direction of that change. It therefore quantifies the specimen’s colour inconstancy under changes of lighting.

Scope

This part of ISO 105 specifies an instrumental (colourimetric/spectrophotometric) procedure to calculate an estimate of the magnitude — and optionally the orientation — of the change in perceived colour of a textile specimen when the chromaticity of the illumination changes. The method is intended to provide an objective estimate of “colour inconstancy” (distinct from, but related to, metamerism) and includes the measurement, calculation method (CMCCON02) and interpretation of results in a standardised test report. The standard cross‑references relevant CIE publications and other parts of ISO 105 for measurement principles.

Key topics and requirements

• Definition and objective: instrumental assessment of colour inconstancy when illumination chromaticity changes (CMCCON02).
• Measurement principle: colourimetric/spectrophotometric measurement of specimen under defined reference and test illuminants, with calculations to estimate perceptual change.
• Calculation method: algorithm/formula (CMCCON02) to quantify magnitude and optionally direction of hue shift.
• Required references: normative references to relevant CIE publications (for example CIE Pub. 159) and other ISO 105 parts for measurement procedures and interpretation.
• Test report: guidance on reporting measured values, calculated inconstancy estimate and any test conditions or deviations.

Typical use and users

Used by textile and apparel laboratories, quality control teams, textile researchers, colour scientists and materials suppliers to assess how a fabric’s perceived colour may change under different lighting conditions. It supports product development, quality assurance, supplier evaluation and technical claims about colour performance under multiple illuminants. National standards bodies and conformity assessment bodies also adopt this part as an identical EN/SS/BS national publication for harmonised testing.

Related standards

ISO 105-J05 is part of the ISO 105 family (Textiles — Tests for colour fastness) and is intended to be used together with other parts that cover measurement principles and calculation of colour differences, for example ISO 105-J01 (general principles for measurement of surface colour), ISO 105-J03 (calculation of colour differences) and other ISO 105 series parts and national/EN adoptions. The standard also references CIE publications used for colourimetric calculations.

FAQ

Q: What is this standard?

A: ISO 105-J05:2007 is an ISO standard that specifies an instrumental colourimetric method (CMCCON02) to estimate the magnitude — and optionally the direction — of perceived colour change of textile specimens when the illuminant chromaticity changes.

Q: What does it cover?

A: It covers the measurement principle, calculation method and reporting for assessing colour inconstancy under changes of illumination, including references to the normative colourimetric material required for the calculations.

Q: Who typically uses it?

A: Textile test laboratories, colour scientists, product developers, quality assurance teams in textile and apparel manufacturing, standards bodies and laboratories performing EN/ISO harmonised testing.

Q: Is it current or superseded?

A: As published in March 2007 (Edition 1), ISO 105-J05 has been subject to ISO’s periodic review cycle and is listed as published and confirmed in ISO’s records (confirmed stage 90.93; last confirmation recorded 6 September 2022).
