ISO 105-B06: Textiles – Tests for Colour Fastness – Part B06: Colour Fastness and Ageing to Artificial Light at High Temperatures: Xenon Arc Fading Lamp Test

Overview and Purpose

ISO 105-B06 is a specific part of the ISO 105 series that deals with the color fastness of textiles. This standard outlines the method for determining the resistance of the color of textiles to the action of artificial light. The test simulates the effect of daylight using a xenon arc fading lamp apparatus, assessing how well the textile retains its color when exposed to light that simulates sunlight at high temperatures. This is crucial for evaluating the durability and longevity of textiles used in various applications, from clothing to automotive interiors.

How the Test is Conducted

1. Sample Preparation: Textile samples are prepared and mounted in a manner that exposes them uniformly to the light source. Control samples or blue wool references are often used alongside the test samples for comparison.
2. Exposure Conditions: The samples are exposed to light from a xenon arc lamp, which closely simulates natural sunlight across the visible, ultraviolet (UV), and infrared (IR) spectra. The standard specifies the conditions for light intensity, temperature, and humidity within the test chamber.
3. Duration: The exposure time is determined based on the specific requirements of the test or the end-use of the textile. The standard provides guidance on selecting appropriate exposure periods to evaluate color fastness effectively.
4. Evaluation: After exposure, the color of the textile samples is compared to the control samples or evaluated against a graded scale. The degree of color change indicates the material’s color fastness and its potential for aging under light exposure.

Purpose of the Standard

• Quality and Durability Assessment: Helps manufacturers and consumers understand the quality and durability of textile products in terms of their color stability when exposed to light.
• Product Development: Assists in the development of textiles with improved color fastness, enhancing product longevity and consumer satisfaction.
• Compliance and Standardization: Provides a standardized method for assessing color fastness, facilitating international trade and comparison of textile products.
