Full title and description

ISO 105‑E11:1994 — Textiles — Tests for colour fastness — Part E11: Colour fastness to steaming. Specifies a laboratory method to determine the resistance of textile dyes to steaming at atmospheric pressure by exposing a rolled specimen in contact with specified adjacent fabrics to steam from boiling water and assessing staining with the ISO grey scale.

Abstract

The document gives a standardized procedure for evaluating the tendency of textile coloration to bleed or stain adjacent fabrics during exposure to steam at atmospheric pressure. A test specimen (any textile in any form) is placed in contact with specified adjacent fabrics, rolled into a cylinder, positioned in the neck of a vessel containing boiling water so that it is exposed to steam, and subsequently evaluated for staining of the adjacent fabrics using the ISO grey scale for assessment of staining.

General information

• Status: Published (current edition at time of last ISO confirmation).
• Publication date: 15 September 1994.
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 59.080.01 — Textiles in general.
• Edition / version: Edition 3 (1994).
• Number of pages: 2.

Scope

Applies to textiles of all kinds and in all forms at any stage of manufacture. The standard defines the apparatus set‑up and specimen/adjoining fabric arrangement used to expose samples to steam at atmospheric pressure, and specifies the assessment method for staining of adjacent fabrics using the ISO grey scale. The method is intended to detect dye bleeding or migration that may occur during processes that involve steam (for example certain finishing, steaming or heat‑setting operations).

Key topics and requirements

• Test principle: specimen in contact with specified adjacent fabrics is rolled and exposed to steam from boiling water at atmospheric pressure.
• Specimen and adjacent‑fabric arrangement and preparation (use of specified adjacent fabrics to detect staining).
• Apparatus: cylindrical roll placed in the neck of a flask or vessel containing boiling water to produce steam exposure.
• Assessment: evaluation of staining of the adjacent fabrics with the ISO grey scale for staining (visual comparison).
• Applicability: textiles of all fibre types and product forms; suitable for quality control, specification and comparative testing.

Typical use and users

Used by textile testing laboratories, quality control departments in textile and apparel manufacturing, dye and finishing houses, mills and research organizations that need to assess dye migration or bleeding under steam exposure. Also used by standards bodies and specification writers to reference a repeatable laboratory method for colour‑fastness to steaming.

Related standards

ISO 105 is a multipart series on tests for colour fastness. Closely related parts include ISO 105‑A01 (general principles), ISO 105‑A02 / A03 (grey scales for assessment), and other E‑parts dealing with aqueous and steam/heat treatments (for example ISO 105‑E01, E02, E03, E04, E08, E10, E12, E13, E14, E16). Adjacent‑fabric specifications are given in ISO 105‑F parts. For overall test principles and assessment methods consult ISO 105‑A01 and the relevant A‑parts (grey scale guidance).

FAQ

Q: What is this standard?

A: ISO 105‑E11:1994 is a laboratory test method in the ISO 105 series that specifies how to evaluate colour fastness of textiles to steaming at atmospheric pressure (i.e., whether dyes bleed or stain adjacent fabrics when exposed to steam).

Q: What does it cover?

A: It covers specimen preparation and arrangement with specified adjacent fabrics, the apparatus arrangement for steam exposure (rolled specimen placed in the neck of a flask with boiling water), and the assessment of staining of adjacent fabrics using the ISO grey scale for staining.

Q: Who typically uses it?

A: Textile testing laboratories, manufacturers (dyers, finishers, mills), apparel brand quality teams, research labs and standards committees use the method for quality control, specification compliance and comparative testing.

Q: Is it current or superseded?

A: This is the 3rd edition published 15 September 1994. According to ISO public records the edition was reviewed and confirmed in ISO's periodic reviews (most recently confirmed on 20 November 2020), so the 1994 edition remained the published edition at the time of that confirmation. Users should consult their national standards body or ISO catalogue for any status changes after that confirmation date if they require absolute up‑to‑date confirmation.

Q: Is it part of a series?

A: Yes. ISO 105 is a multipart series of colour‑fastness tests (general principles, assessments and many specific test parts). E11 is one part of the E subsection (tests to aqueous/steam/related agents) and is intended to be used alongside the A‑parts (grey scales and general principles) and relevant F‑parts (adjacent‑fabric specifications).

Q: What are the key keywords?

A: Colour fastness, steaming, steam exposure, adjacent fabric, dye bleeding, grey scale, ISO 105, textile testing.
