Full title and description

ISO 105‑G01:2016 — Textiles — Tests for colour fastness — Part G01: Colour fastness to nitrogen oxides. This International Standard specifies laboratory methods to assess the resistance of textile colours to exposure to nitrogen oxides produced during combustion and by heated filaments; the document is published by the International Organization for Standardization (ISO).

Abstract

ISO 105‑G01:2016 specifies two test methods (of differing severity) for determining the resistance of textile colour to the action of nitrogen oxides (NOx). One or both methods are used depending on the results obtained; the tests address change in colour and staining of adjacent fabrics under controlled exposure conditions.

Scope

The standard applies to textiles of all kinds and in all forms and provides two laboratory procedures to determine how resistant the colour of a textile is to nitrogen oxides produced by combustion processes or by hot filaments in air. The scope covers test selection (one or both methods), exposure conditions and the evaluation of colour change and staining relevant to material performance and quality control.

Key topics and requirements

• Two alternative exposure methods for nitrogen oxides with different severities; selection criteria for which test(s) to use.
• Preparation and conditioning of test specimens and adjacent fabrics prior to exposure.
• Controlled exposure conditions and duration to simulate NOx attack from combustion or heated filaments.
• Evaluation procedures for assessing change in colour and staining (comparative assessment against reference specimens or scales as appropriate).
• Reporting requirements and interpretation guidance for results used in quality control or specification compliance.

The list above summarises the principal topics addressed by the standard; the ISO text gives the definitive procedural and reporting details.

Typical use and users

Used by textile manufacturers, dye houses, independent test laboratories, product development teams and quality assurance/inspection departments to verify colour fastness performance against NOx exposure. It is also referenced by product specifiers and purchasing departments when colour durability in polluted or combustion-prone environments is a concern. Practical applications include apparel, technical textiles and materials used in environments where NOx exposure may accelerate colour change.

Related standards

ISO 105 is a multipart series covering many different colour‑fastness tests (washing, light, rubbing, water, perspiration, spotting, etc.). Closely related parts include ISO 105‑G04 (colour fastness to nitrogen oxides in the atmosphere at high humidities) and other ISO 105 parts that specify assessment principles, adjacent fabrics and alternative exposures. These related parts provide complementary methods and reference procedures within the ISO 105 series.

FAQ

Q: What is this standard?

A: ISO 105‑G01:2016 is part G01 of the ISO 105 series (Textiles — Tests for colour fastness) and defines laboratory tests for colour fastness to nitrogen oxides.

Q: What does it cover?

A: It covers two controlled laboratory methods to expose textile specimens to nitrogen oxides and to assess consequent change in colour and staining; the methods differ in severity and are selected according to the sample and required assessment.

Q: Who typically uses it?

A: Textile and dye manufacturers, independent test laboratories, product developers, QA teams and specifiers who need to verify or specify colour stability where exposure to combustion products or heated filaments (NOx) is relevant.

Q: Is it current or superseded?

A: ISO 105‑G01:2016 is the current edition (edition 3, published 2016) and the ISO catalogue entry indicates the publication was reviewed and confirmed at its five‑year review (confirmation recorded in 2021). The 2016 edition supersedes the earlier ISO 105‑G01:1993.

Q: Is it part of a series?

A: Yes — it is one part of the multipart ISO 105 series (Textiles — Tests for colour fastness); that series includes numerous parts covering washing, light, rubbing, water, perspiration, spotting and other specific exposures and assessment methods.

Q: What are the key keywords?

A: Colour fastness, nitrogen oxides, NOx, textile testing, ISO 105, colour durability, exposure testing.
