Full title and description

ISO 105-B01:2014 — Textiles — Tests for colour fastness — Part B01: Colour fastness to light: Daylight. This international standard specifies a controlled outdoor exposure method for determining the resistance of textile colours to daylight by simultaneous exposure of test specimens and blue wool reference strips under defined siting, glazing and mounting conditions.

Abstract

ISO 105-B01:2014 defines a standardized procedure for assessing the lightfastness of textile materials and products when exposed to natural daylight. The method permits the use of two different sets of blue wool references and allows assessment by visual comparison or instrumental measurement, with specific requirements for exposure racks, glazing, specimen mounting and reporting of results.

Scope

This part of ISO 105 specifies a method intended for determining the resistance of the colour of textiles of all kinds and in all forms to the action of daylight. It covers simultaneous exposure of test specimens with blue wool reference strips, selection and use of one of two permitted blue-wool reference sets, siting of exposure racks (orientation and slope), glazing requirements, specimen size and mounting, environmental siting considerations (avoidance of pollution and shadows), and procedures for assessing and reporting colour change. The standard notes that results obtained with the two different reference sets may not be identical.

Key topics and requirements

• Principle: simultaneous outdoor exposure of specimens and blue wool references to daylight and assessment of fading by visual or instrumental comparison.
• Blue wool reference systems: two permitted reference sets (different numbering/constructions) — results from different sets are not directly interchangeable.
• Exposure siting and orientation: rack orientation and slope specified (e.g., face south in Northern Hemisphere), and siting to avoid local pollution, reflections and shadows.
• Glazing and protection: requirements for glazing (flat drawn glass with specified transmission characteristics) to protect specimens from weather while controlling spectral transmission.
• Specimen mounting and dimensions: defined minimum specimen sizes and mounting methods to ensure reproducible exposure.
• Assessment methods: visual assessment against grey scales and/or instrumental colour measurement; reporting of blue-wool fade steps and specimen change.
• Reporting and limitations: required details in test reports (reference set used, exposure location and period, glazing, mounting, environmental notes) and a caution that conversion between reference systems is not permitted.

Typical use and users

Used by textile test laboratories, dye and fibre manufacturers, apparel and home-textile quality departments, outdoor-fabric manufacturers, product developers and standards bodies to evaluate and compare material lightfastness under real daylight exposure conditions. The standard supports quality control, product development, claims substantiation and regulatory or specification compliance.

Related standards

ISO 105 is a multipart series on tests for colour fastness; related parts include other ISO 105 sections covering water, sea water, rubbing, perspiration and assessment procedures (for example ISO 105-E01 for colour fastness to water and other ISO 105 series parts). National/adopted variants (EN ISO versions) exist for use in regional markets.

A: ISO 105-B01:2014 is an international test method that specifies how to assess the resistance of textile colours to natural daylight exposure using blue wool references and controlled outdoor exposure conditions.

Q: What does it cover?

A: It covers the test principle, permitted blue wool reference systems, exposure rack siting and orientation, glazing/transmission requirements, specimen size and mounting, assessment (visual or instrumental) and reporting requirements for daylight lightfastness testing.

Q: Who typically uses it?

A: Textile manufacturers, test laboratories, dye houses, product developers, quality assurance teams and standards or regulatory organizations use this standard to evaluate and document lightfastness of textiles.

Q: Is it current or superseded?

A: ISO 105-B01:2014 is a published international standard (Edition 6, 2014). The ISO record lists this edition as published and confirmed in subsequent review cycles, so it is current in its confirmed status.
