Full title and description

ISO 105-B02:2014 — Textiles — Tests for colour fastness — Part B02: Colour fastness to artificial light: Xenon arc fading lamp test. The standard specifies an accelerated artificial-light exposure method (xenon-arc) representative of natural daylight (D65) to assess colour change and related effects on textile materials.

Abstract

ISO 105-B02:2014 provides a laboratory procedure using a xenon arc fading lamp to determine the effect of artificial daylight on the colour of textiles of all kinds and in all forms. The method is applicable to coloured and white (bleached or optically brightened) textiles, and permits the use of two different sets of blue wool reference standards for lightfastness comparison.

Scope

Specifies a xenon-arc exposure test intended to determine resistance of textile colours to artificial light representative of natural daylight (D65). The procedure covers specimen preparation, exposure conditions, use of blue wool references, assessment of change and staining, and reporting of results; it can be applied to all textile types including bleached or optically brightened white materials.

Key topics and requirements

• Principle of xenon-arc fading lamp exposure to simulate daylight (D65) and accelerated lightfastness evaluation.
• Required apparatus and device performance criteria for xenon arc exposure units (irradiance, filters, temperature and humidity control).
• Specimen preparation, mounting and conditioning before exposure.
• Exposure conditions, test cycles and measurement intervals; procedures for measuring irradiance uniformity in the specimen area (annex for apparatus manufacturers).
• Assessment methods using blue wool reference scales (two permitted reference sets) and reporting of lightfastness grades and test data.
• Informative annexes with light-exposure equivalents for blue wool references and normative requirements for xenon-arc devices.

Typical use and users

Used by textile testing laboratories, manufacturers, dye and finish technologists, quality assurance and R&D teams, certification bodies and standards committees to evaluate and compare lightfastness of fabrics, yarns and finished textile products under controlled simulated daylight exposure. Test houses and conformity assessment organizations commonly apply this method for product specifications and quality control.

FAQ

Q: What is this standard?

A: ISO 105-B02:2014 is an ISO test method that specifies how to assess the effect of artificial daylight (xenon-arc lamp) on the colour of textile materials (lightfastness/fading).

Q: What does it cover?

A: It covers apparatus requirements, specimen preparation, exposure conditions, procedures for running xenon-arc exposures, assessment against blue wool references and reporting requirements (including several normative and informative annexes).

Q: Who typically uses it?

A: Textile test laboratories, manufacturers, dye houses, product specifiers, quality assurance teams and conformity assessment bodies use this standard for product development, acceptance testing and quality control.

Q: Is it current or superseded?

A: The 2014 edition is the published replacement of the withdrawn 2013 edition; ISO lists ISO 105-B02:2014 as the current published edition (Edition 6, 2014) and notes the 2013 edition was withdrawn and superseded by the 2014 text. Users should check national/adopted versions (EN/BSI adoptions) or ISO reviews for confirmation of current status before formal citation.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 105 series (Textiles — Tests for colour fastness), a comprehensive family of parts covering light, weathering, washing, rubbing, chemical and other colour-fastness tests.

Q: What are the key keywords?

A: Key keywords include: colour fastness, lightfastness, xenon arc, fading lamp test, D65, blue wool references, accelerated exposure, ISO 105-B02.
