Full title and description

ISO 105-B06:2020 — Textiles — Tests for colour fastness — Part B06: Colour fastness and ageing to artificial light at high temperatures: Xenon arc fading lamp test. This international standard specifies a xenon-arc exposure method to determine colour fastness and ageing behaviour of dyed or printed textiles and other organic substrates under artificial daylight (D65) conditions combined with elevated temperature, with particular attention to conditions found inside motor vehicles.

Abstract

The document defines a test method using a xenon arc fading lamp and specified optical filters and exposure schedules (five sets of exposure conditions) to assess colour change and ageing at high temperatures. Four exposure sets use D65 spectral characteristics and one uses a slightly lower cut-off wavelength; results obtained with different apparatus types or filter systems are not directly comparable. The method is aimed at all forms of dyed and printed textiles and similar organic substrates.

Scope

Specifies a laboratory method to determine colour fastness and ageing of textiles and other organic substrates when exposed to an artificial daylight-representative xenon-arc source at elevated temperatures. The procedure includes defined optical filtering systems and five exposure-condition sets to model different service environments (including vehicle interiors). It notes that results are dependent on the chosen exposure set and apparatus type, and comparability between different instrument types has not been validated.

Key topics and requirements

• Use of a xenon arc fading lamp to simulate daylight (D65) combined with controlled heat for accelerated light-ageing tests.
• Definition of five exposure-condition sets (four using D65, one with a lower cut-off wavelength) and associated optical filter systems.
• Requirements for specimen mounting, temperature control, irradiance measurement, and exposure duration to produce reproducible results.
• Guidance that results from different apparatus types or different optical filter systems are not directly comparable unless validated.
• Special consideration of conditions relevant to motor-vehicle interiors (light plus heat).

Typical use and users

Used by textile test laboratories, manufacturers of dyed/printed textiles, automotive interior suppliers, quality assurance teams, material scientists, and regulatory bodies to evaluate resistance to light-induced colour change and heat-accelerated ageing. It supports product development, supplier verification, claims substantiation, and comparative performance assessment when using the same validated apparatus and filter configuration.

Related standards

Part of the ISO 105 series (Tests for colour fastness) and is closely related to other B‑series parts for light and weathering tests (e.g., ISO 105-B01, ISO 105-B02, ISO 105-B08) and the A-series general principles and assessment methods (see ISO 105-A01 for the list of parts). Many regions publish harmonized EN ISO versions for use in Europe. Alternative/complimentary test methods (AATCC, ASTM) may be used for specific markets or test types.

FAQ

Q: What is this standard?

A: ISO 105-B06:2020 is an international test method specifying a xenon-arc lamp procedure to evaluate colour fastness and ageing of dyed or printed textiles and related organic substrates under artificial daylight at elevated temperatures.

Q: What does it cover?

A: It covers apparatus, optical filtering, exposure conditions (five defined sets), specimen preparation and mounting, measurement and assessment of colour change and ageing effects, and notes limitations on comparability between different instrument types and filter systems.

Q: Who typically uses it?

A: Accredited test labs, textile and apparel manufacturers, automotive suppliers (interior textiles), R&D and QA teams, and standards bodies use it to assess product durability to light and heat.

Q: Is it current or superseded?

A: The 2020 edition (Edition 3) is the current published ISO version (revises and replaces the 1998 edition and its amendment). ISO standards are reviewed periodically (typically every five years) and this edition is listed as published/confirmed.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 105 series (Tests for colour fastness). The series includes A‑parts (general principles and assessment methods) and multiple B, C, D, E, F, etc. parts that cover light, washing, rubbing, water, and other colour fastness tests. Consult ISO 105-A01 for the series overview.
