Textiles - Tests for colour fastness - Part N05: Colour fastness to stoving (ISO 105-N05:1993)

Specifies a method for determining the resistance of the colour of textiles of all kinds and in all forms to the action of sulfur dioxide as used for bleaching animal fibres. A composite specimen containing its own mass of soap solution and a composite test-control specimen are exposed in an atmosphere containing sulfur dioxide. The change in colour of the specimen and the staining of the adjacent fabric(s) are assessed with the grey scale.

Overview

EN ISO 105-N05:1995 is a European adoption of the ISO 105-N05:1993 international standard, developed by CEN, that specifies a reliable method for testing the colour fastness of textiles to stoving. This test evaluates how resistant textile colours are to sulfur dioxide exposure, particularly important for animal fibres subjected to bleaching. The standard applies to textiles of all types and forms, providing a systematic approach to assess colour durability under conditions simulating industrial bleaching processes.

Key Topics

• Scope and Purpose
  The standard covers a testing method to determine resistance of textile colours to sulfur dioxide as used in stoving, a bleaching technique for animal fibres. It measures colour change and staining on adjacent fabrics.

• Test Principles
  A composite specimen soaked in a specific soap solution and a test-control specimen are exposed together to a sulfur dioxide atmosphere generated by burning sulfur. Colour changes in the test specimen and adjacent staining are subsequently evaluated using standardized grey scales.

• Specimen Preparation
  The textile sample is combined with adjacent fabrics (multifibre or single-fibre) to detect staining effects. Specimens are impregnated with a soap solution before exposure and then evaluated after drying or rinsing based on fabric composition.

• Assessment Tools
  The grey scale for assessing colour change (ISO 105-A02) and staining (ISO 105-A03) are mandatory tools for rating test outcomes, ensuring consistent and objective evaluation.

• Test Conditions
  Exposure takes place in a controlled sulfur dioxide atmosphere within a 10-litre vessel for 16 hours to simulate stoving conditions. Soap solution and water quality are strictly specified to standardize test results.

Applications

• Textile Industry Quality Control
  Manufacturers use EN ISO 105-N05:1995 to verify the resistance of dyed animal fibre textiles to sulphur dioxide bleaching, ensuring colour durability and product quality before market release.

• Material Research and Development
  This standard assists R&D teams in formulating and selecting dyes and treatments that improve textile resistance to bleaching and chemical exposure.

• Regulatory Compliance
  Helps ensure products meet industry and customer specifications regarding colour fastness, supporting compliance with European and international textile quality standards.

• Performance Benchmarking
  Enables comparative testing of different textile products and dyes to promote continuous improvement in colour fastness performance within the industry.

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 l05-NO5 was prepared by Technical Committee
lSO/rC 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-N:l978), 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 “).
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-AOI.
