General Information
Overview
SIST EN ISO 105-Z02:1999 is an international standard developed by CEN that specifies a method for testing the colour fastness of textiles to metals in the dyebath, specifically focusing on iron and copper. These metals can be present in dyeing processes due to their use in dyeing machinery or the water and steam involved. The standard assesses the impact these metal salts have on the colour stability of dyed textiles by comparing dyeings made with and without metal salts, using a grey scale for evaluation.
This test is critical in ensuring the durability and consistency of textile colours, helping manufacturers identify potential issues caused by metal contamination during dyeing. It supports quality assurance for textiles exposed to iron and copper in the production environment.
Key Topics
- Colour fastness testing: Measures fabric resistance to colour change in the presence of metal ions.
- Metals in dyebath: Focused on iron (ammonium iron(III) sulfate) and copper (copper(II) sulfate) salts that may affect dye stability.
- Test principle: Comparison of dyeings done with and without metal salts in the dyebath.
- Materials used:
- Undyed light wool fabric as test specimen.
- Standard dye-baths with added metal salt solutions.
- Grey scale for assessing colour change as per ISO 105-A02.
- Test procedure:
- Dye three fabric samples: one without metal salts, one with copper(II) sulfate, one with ammonium iron(III) sulfate.
- Maintain a consistent liquor ratio, typically 40:1.
- Assess and rate colour differences using the grey scale.
- Reporting: Includes dye specifics, method, and numerical ratings for colour change to document fastness levels.
Applications
SIST EN ISO 105-Z02:1999 is especially valuable in the textile industry for:
- Quality control in textile manufacturing to monitor the influence of metal contaminants on dye stability.
- Research and development for improving dye formulations and machinery materials to enhance colour fastness.
- Ensuring compliance with customer and regulatory requirements for durable and colour-consistent textiles.
- Testing textiles destined for uses where exposure to metal ions is likely, such as in industrial washing, steam treatments, or water with high metal content.
- Assisting dyehouse operators in assessing the performance of dye processes and mitigating undesirable colour changes caused by iron or copper residues.

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 105-202 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-Z: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 “).
These sections are now being republished as separate documents, them-
selves designated “Parts” but retaining
