EN ISO 105-J05:2007

• Abstract:

  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.

Overview

EN ISO 105-J05:2007 is a European and international standard developed by CEN and ISO for the textile industry. Titled Textiles - Tests for colour fastness - Part J05: Method for the instrumental assessment of the colour inconstancy of a specimen with change in illuminant (CMCCONO2), this standard provides a reliable, colorimetric method to estimate how much the perceived color of a textile changes under different lighting conditions. This technique is crucial in analyzing and quantifying the colour inconstancy of textiles, supporting quality control and consistency in textile production and finishing.

The standard outlines a process for instrumental assessment, focusing on the effects of changing illuminants on single textile specimens. It quantifies the magnitude of color shifts using established color measurement techniques, ensuring objective and reproducible results.

Key Topics

• Colour Inconstancy versus Metamerism:

  • Colour inconstancy refers to how the color of a single textile specimen changes under different light sources.
  • Metamerism involves how the perceived color difference between two specimens changes under varied illumination.

• Instrumental Assessment:

  • The standard specifies the use of colorimetric instruments (such as spectrophotometers or colorimeters) to measure tristimulus values based on agreed illuminants, often using CIE Standard Illuminant D65 and a test illuminant.
  • Calculation is based on the CMCCON02 index, providing an objective metric for color inconstancy.

• Chromatic Adaptation Transform (CAT02):

  • The methodology employs chromatic adaptation transforms to assess and convert color measurements between different illuminants, increasing accuracy.

• Reporting Requirements:

  • Test reports must include all relevant measurement conditions, instrument details, test illuminant, calculation method, and the resulting CMCCON02 value.

Applications

• Textile Design & Manufacturing:

  • Ensures that textile products display consistent color appearance under diverse lighting environments (e.g., retail stores, daylight, home lighting), reducing customer returns and complaints.
  • Supports dye selection and quality control by providing measurable data on color inconstancy.
  • Applicable for both research and production quality assurance settings.

• Retail and Consumer Goods:

  • Helps brands maintain color quality and consistency across product lines and locations where lighting conditions vary.
  • Valuable for specification and verification when sourcing textiles from multiple suppliers.

• Certification and Compliance:

  • Manufacturers can demonstrate compliance with international standards for color fastness and inconstancy, enhancing global market access.

Related Standards

• ISO 105-J01:Textiles - Tests for colour fastness - Part J01: General principles for measurement of surface colour - foundational principles for color measurement in textiles.
• ISO 105-J03:Textiles - Tests for colour fastness - Part J03: Calculation of colour differences - guidelines for calculating color difference values, referenced in the calculation of the CMCCON02 index.
• CIE Publications (e.g., CIE Publ. 159:2004): Models and protocols for color appearance and management systems.
• ASTM E308:Standard Practice for Computing the Colors of Objects by Using the CIE System - guidance for color computations essential to the methods in EN ISO 105-J05.

EN ISO 105-J05:2007 plays a vital role in the textile industry, offering a standardized, objective approach to evaluating and managing color inconstancy, and supporting enhanced color quality across the global supply chain.

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
coloured textiles and colorants.
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.
