Full title and description

ISO 105‑G02:1993 — Textiles — Tests for colour fastness — Part G02: Colour fastness to burnt‑gas fumes. Specifies a laboratory method to determine the resistance of coloured textiles (all forms except loose fibres) to atmospheric oxides of nitrogen produced by the combustion of chemically pure butane; changes in colour are assessed using the ISO grey scale.

Abstract

This standard describes a test procedure for exposing textile specimens to oxides of nitrogen derived from the controlled combustion of pure butane gas and for assessing the resulting change in colour. The method can be used both for testing dyed textile materials and for rating dyes applied under specified conditions; evaluation of change is made using the ISO grey scale for change in colour.

Scope

Applies to textiles of all types and in all forms except loose fibres. The standard specifies apparatus, test specimen preparation, the controlled combustion source (chemically pure butane), exposure conditions and the assessment procedure for determining the degree of change in colour caused by atmospheric oxides of nitrogen produced during the combustion. It is intended for use in routine quality assessment of dyed textiles and for comparative rating of dyes and dyeing procedures.

Key topics and requirements

• Purpose: evaluate resistance of textile colour to burnt‑gas (NOx) exposure.
• Test atmosphere generation: regulated combustion of chemically pure butane to produce oxides of nitrogen under defined conditions.
• Apparatus and sample mounting: description of exposure chamber, burner arrangement and specimen positioning.
• Specimen preparation and conditioning: prescribed sample size, depth of shade and pre‑conditioning before exposure.
• Exposure parameters: controlled exposure duration and environmental controls to ensure repeatability.
• Assessment: evaluation of change in colour using the ISO grey scale and reporting of results.
• Reporting: required test details, results presentation and any deviations from the method.
• Technical corrigenda: the standard has published corrigenda (for example in 1995 and 2009) that amend certain subclauses; users should check for those when applying the method.

Typical use and users

Used by textile and apparel manufacturers, dye and chemical suppliers, independent test laboratories, quality assurance departments and research institutions to assess and document colour fastness to combustion‑derived nitrogen oxides. Also referenced by compliance and certification bodies when evaluating product performance against customer or regulatory requirements.

Related standards

Part of the ISO 105 series (Textiles — Tests for colour fastness). Commonly used companion parts include ISO 105‑A01 (general principles), ISO 105‑A03 (grey scale for assessing staining), the ISO 105 B series (colour fastness to light and weathering), and other G‑series parts such as ISO 105‑G03 (colour fastness to ozone). Laboratories typically apply ISO 105‑G02 alongside relevant ISO 105 parts appropriate to the exposure or agent of interest.

FAQ

Q: What is this standard?

A: ISO 105‑G02:1993 is a method standard in the ISO 105 series that specifies how to test the colour fastness of textiles to fumes produced by the controlled combustion of chemically pure butane (burnt‑gas fumes), and how to assess any change in colour.

Q: What does it cover?

A: It covers apparatus, specimen preparation, exposure conditions, assessment (using the ISO grey scale) and reporting for tests that expose textile specimens to atmospheric oxides of nitrogen generated from pure butane combustion. It excludes loose fibres.

Q: Who typically uses it?

A: Textile manufacturers, dye producers, independent laboratories, QA teams, research organizations and certification bodies that need to evaluate or compare colour fastness performance under combustion‑derived NOx exposure.

Q: Is it current or superseded?

A: The 1993 (Edition 2) version is the published edition; technical corrigenda have been issued (for example in 1995 and 2009). The standard has been subject to ISO review cycles and continues to be listed as the current edition unless superseded by a later numbered revision—users should verify the latest status with the ISO catalogue or their national standards body before relying on it for regulatory or contractual work.

Q: Is it part of a series?

A: Yes. ISO 105‑G02 is one part of the ISO 105 series, which contains many specific methods for colour fastness to different agents (light, washing, perspiration, gases, ozone, etc.).

Q: What are the key keywords?

A: Colour fastness, burnt‑gas fumes, butane, oxides of nitrogen, ISO 105, grey scale, textile testing, dye fastness.
