Full title and description

ISO 105-G03:1993 — Textiles — Tests for colour fastness — Part G03: Colour fastness to ozone in the atmosphere. Specifies a laboratory method to determine the resistance of textile colours to the action of atmospheric ozone under defined temperature and humidity conditions. Available as an ISO PDF/publication (second edition, 1993).

Abstract

This part of ISO 105 prescribes a method for determining the resistance of the colour of textiles of all kinds and in all forms to the action of ozone in the atmosphere. The method covers exposure at ambient room temperatures (relative humidity not exceeding 65%) and at elevated temperatures with relative humidities above 80%. The procedure defines exposure conditions, specimen preparation, assessment of colour change and staining, and reporting requirements. If sensitivity to ozone is observed, complementary tests for nitrogen oxides (ISO 105‑G01) and combustion gas fumes (ISO 105‑G02) are recommended.

Scope

The standard defines a controlled laboratory test to assess how textile dyes and coloured materials resist degradation or change in colour when exposed to ozone in air. It sets out specimen conditioning, ozone concentration and exposure time, required ambient and elevated temperature/humidity ranges, methods for visual and instrumental assessment of colour change and staining, and the format for reporting test results. It is intended for use with textiles of all constructions and forms.

Key topics and requirements

• Definition of ozone exposure conditions (concentration, exposure time, airflow).
• Two ambient regimes: normal room conditions (RH ≤ 65%) and elevated temperature/high humidity (RH > 80%).
• Specimen preparation, mounting and conditioning before test.
• Assessment methods for colour change and staining (visual greyscales and/or instrumental measurement) and acceptance criteria reporting.
• Calibration and verification of the ozone generator and environmental controls.
• Requirement to consider complementary gas-exposure tests (ISO 105‑G01, ISO 105‑G02) if sensitivity is detected.
• Reporting templates covering sample identification, test parameters, results and observations.

Typical use and users

Used by textile and apparel manufacturers, dye and chemical suppliers, independent textile testing laboratories, quality assurance teams, product development groups and regulatory bodies concerned with outdoor durability and colour stability of dyed textiles. It is applied in failure analysis, material specification, conformity testing and comparative performance evaluations.
