Overview

EN ISO 105-G03:1997 – Textiles – Tests for Colour Fastness – Part G03: Colour Fastness to Ozone in the Atmosphere is an international standard developed by CEN and ISO. This document defines a testing method for assessing the resistance of textile colors to atmospheric ozone. The standard applies to all kinds of textiles, regardless of their composition or form – including fabrics, yarns, and fibers.

Ozone in the atmosphere is a common cause of fading and discoloration, especially in environments with high humidity and warm temperatures. This standard ensures that textile products are tested consistently for their ability to withstand such exposure, promoting quality, reliability, and longevity in textiles across industries.

Key Topics

• Colour Fastness Testing: The standard focuses on procedures for determining how a textile’s color resists fading when exposed to ozone.
• Test Conditions: EN ISO 105-G03 specifies two principal test conditions:
  • Ambient room temperatures with relative humidities not exceeding 65%
  • Elevated temperatures with relative humidities above 80%
• Sample Preparation: Guidance is given for preparing specimens from fabrics, yarns, or loose fibers.
• Ozone Exposure Chambers: Details on the required test equipment for controlled ozone exposure at specified temperature and humidity settings.
• Assessment of Results: The color change is evaluated using standardized grey scales, ensuring repeatable and objective results.
• Reporting: Requirements for reporting all relevant details of the test, including ambient conditions, number of cycles, and extent of color change.

Applications

EN ISO 105-G03:1997 has practical relevance across the textile industry and beyond:

• Quality Control: Essential for textile manufacturers seeking certification of product durability and color retention, particularly for items expected to endure outdoor or high-ozone environments.
• Textile Research and Development: Used in R&D laboratories for developing new dyeing processes and fiber blends with enhanced ozone resistance.
• Compliance and Regulatory Testing: Ensures textile exports and imports meet international standards related to color durability.
• Product Labelling: Supports accurate labeling regarding color fastness, benefiting consumers and businesses in making informed decisions.
• Sustainability: Encourages adoption of dyes and finishes that minimize color loss, reducing waste and increasing product lifespan.

Industries applying this standard include apparel, upholstery, automotive interiors, technical textiles, and outdoor gear suppliers.

Related Standards

Organizations typically employ EN ISO 105-G03 in conjunction with other color fastness standards to achieve comprehensive textile testing:

• EN ISO 105-A01: General principles of testing for color fastness.
• EN ISO 105-A02: Methods for assessing change in color using the grey scale.
• EN ISO 105-F: Standards for adjacent fabrics used in fastness testing.
• EN ISO 105-G01: Colour fastness to nitrogen oxides.
• EN ISO 105-G02: Colour fastness to burnt-gas fumes.

Using EN ISO 105-G03 alongside these related standards ensures rigorous, holistic assessments of textile color durability in various environmental conditions.

Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national Standards bodies (ISO member bodies). The work
of preparing International Standards is normally carried out through ISO
technical committees. Esch member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 105-G03 was prepared by Technical Committee
lSO/TC 38, Textiles, Sub-Committee SC 1, Tests for coloured textiles and
coloran ts.
This second edition cancels and replaces the first edition (included in
ISO 105-G:1978), of which it constitutes a minor revision.
ISO 105 was previously published in thirteen “Parts”, each designated by
a letter (e.g. “Part A”), with publication dates between 1978 and 1985.
Esch part contained a series of “sections”, each designated by the re-
spective part letter and by a two-digit serial number (e.g. “Section AO1 “1.
These sections are now being republished as separate documents, them-
selves designated “Parts” but retaining their earlier alphanumeric desig-
nations. A complete list of these Parts is given in ISO 105-AOl .
Annexes A and B form an integral part of this part of ISO 105. Annex C is
