Full title and description

UNE-EN ISO 105-E11:1997 — Textiles. Tests for colour fastness. Part E11: Colour fastness to steaming. This UNE adoption is identical to ISO 105‑E11:1994 and specifies a laboratory method to assess the resistance of textile colour to the action of steam at atmospheric pressure by rolling a test specimen with specified adjacent fabrics and exposing the assembly to steam; staining of the adjacent fabrics is evaluated using a grey scale.

Abstract

This standard describes a comparative test in which a specimen of textile material (of any kind or form) is placed in contact with specified adjacent fabrics, rolled into a cylinder and held in the neck of a flask over boiling water so that the specimen is exposed to steam. After exposure, the degree of staining (bleeding or migration of dye) onto the adjacent fabrics is assessed visually against a grey scale to give a colour‑fastness rating. The method is intended for routine quality control and comparative assessment of dye stability to steaming.

General information

• Status: Adopted as a UNE national implementation of EN/ISO; listed as active/vigente in UNE/AENOR catalogues.
• Publication date: 13 May 1997 (UNE adoption). The underlying ISO edition is ISO 105‑E11:1994 (published 15 Sep 1994).
• Publisher: AENOR (as UNE national body) — original international text published by ISO.
• ICS / categories: 59.080.01 — Textiles in general.
• Edition / version: UNE-EN ISO 105‑E11:1997 (identical to ISO 105‑E11:1994, edition 3).
• Number of pages: National publication varies; UNE listing records the 1997 adoption (national PDF) — ISO original document is concise (short technical sheet), national reproductions typically range around 5–15 pages depending on national forewords and translations (UNE listing indicates the national file published in 1997).

Key bibliographic and status details are recorded by ISO and by the UNE/AENOR catalogue for the 1997 adoption.

Scope

The standard applies to textiles of all kinds and in all forms and specifies a laboratory procedure for determining how a textile’s colour withstands exposure to steam at atmospheric pressure. It is intended for comparative testing and quality control rather than to predict long‑term in‑service behaviour under different end‑use conditions. The procedure uses specified adjacent fabrics and visual assessment with a grey scale to rate staining.

Key topics and requirements

• Preparation of test specimen and specified adjacent (scouring/adjacent) fabrics for paired contact testing.
• Assembly of specimen and adjacent fabrics into a roll or cylinder to ensure controlled contact.
• Exposure of the assembled test specimen to steam produced by boiling water at atmospheric pressure (test apparatus: flask and glass tube arrangement as described in the method).
• Post‑exposure assessment of staining on adjacent fabrics using the grey scale for change in shade and staining (visual comparative evaluation).
• Reporting of results as grey‑scale ratings and any relevant test conditions or deviations.

Typical use and users

Used by textile testing laboratories, dye houses, fabric and garment manufacturers, quality control departments, third‑party testing and certification bodies, and standards committees. Typical applications include production quality checks, incoming raw‑material screening, evaluation of dyeing processes and assessment of fabric conversion steps where steam exposure may occur.

FAQ

Q: What is this standard?

A: UNE‑EN ISO 105‑E11:1997 is the Spanish national adoption of the EN/ISO method titled “Textiles — Tests for colour fastness — Part E11: Colour fastness to steaming”, which reproduces ISO 105‑E11:1994. It defines a laboratory test to evaluate dye migration or staining caused by steam exposure.

Q: What does it cover?

A: It covers the preparation of specimens and adjacent fabrics, the arrangement of the specimen into a roll or cylinder, exposure to steam at atmospheric pressure using the described flask/tube apparatus, and the visual assessment of staining on adjacent fabrics using a grey scale. It is intended for comparative and quality‑control testing rather than to simulate all end‑use conditions.

Q: Who typically uses it?

A: Textile and apparel manufacturers, dyeing and finishing plants, independent textile testing laboratories, procurement and QC teams, and conformity assessment bodies use this standard for routine testing of dye stability to steam.

Q: Is it current or superseded?

A: The UNE‑EN ISO 105‑E11:1997 adoption implements ISO 105‑E11:1994. ISO records show the 1994 edition as the active international text and the national EN/UNE adoptions from the mid‑1990s; users should check their national catalogues for any later revisions or newer related parts (the ISO bibliographic record indicates periodic systematic review activity for the ISO 105‑E11 document).

Q: Is it part of a series?

A: Yes — it is one part of the ISO 105 series (“Tests for colour fastness”), a multi‑part family of standards each addressing different agents, treatments and assessment methods for colour fastness in textiles. National EN/UNE adoptions follow the same part numbering when adopted.

Q: What are the key keywords?

A: Colour fastness, steaming, textile testing, grey scale, ISO 105, dye fastness, AENOR, UNE.
