Full title and description

ISO 105‑E06:2006 — Textiles — Tests for colour fastness — Part E06: Colour fastness to spotting: Alkali. This International Standard specifies a laboratory method to determine the resistance of the colour of textiles (all kinds and forms) to the action of dilute alkaline solutions; three tests of differing severity are provided so that appropriate severity can be selected according to fibre and fabric type.

Abstract

Specifies a method for determining the resistance of the colour of textiles to dilute alkaline solutions. The standard provides three severity levels of test; any one or a combination may be used depending on the nature of the fibre and the end-use. The test outcome is used to assess change in colour and staining after application of an alkaline spot.

Scope

Applies to textiles of all kinds and in all forms and specifies a standardized procedure to evaluate the resistance of dyes and coloured materials to the action of dilute alkaline solutions. The procedure is intended to simulate spotting incidents where alkaline solutions contact textile surfaces and to provide a repeatable basis for assessing colour change and staining using an agreed assessment scale. Three tests of differing severity are described so that laboratories can choose the most appropriate method for the material under test.

Key topics and requirements

• Standardised method for applying dilute alkaline spotting reagents to textile specimens and ensuring adequate penetration for assessment.
• Three testing severities (different exposure/interaction conditions) to cover fibre-specific behaviour and end-use sensitivities.
• Assessment of change in colour and staining using an agreed grey scale or equivalent assessment criteria.
• Requirements for sample preparation, reagent concentration (dilute alkaline solutions), application technique and result interpretation.
• Intended use in quality control, specification verification and comparative testing between materials or processes.

Typical use and users

Used by textile test laboratories, manufacturers, dye and finishing houses, quality assurance teams, product designers and procurement/specification engineers to verify colour fastness performance when textiles are exposed to alkaline spotting agents. Also used in research and development when evaluating new dyes, treatments or cleaning/maintenance procedures.

FAQ

Q: What is this standard?

A: ISO 105‑E06:2006 is an ISO test method titled "Textiles — Tests for colour fastness — Part E06: Colour fastness to spotting: Alkali" that specifies procedures to assess resistance of textile colour to dilute alkaline solutions.

Q: What does it cover?

A: It covers the controlled application of dilute alkaline solutions to textile specimens, description of three severity levels of test, and the assessment and grading of colour change and staining (commonly using a grey scale or equivalent).

Q: Who typically uses it?

A: Accredited test laboratories, textile and dye manufacturers, quality control departments, product specifiers and researchers use this standard to evaluate and compare the alkaline-spotting resistance of fabrics and finishes.

Q: Is it current or superseded?

A: The 2006 edition is the current ISO version; ISO records show the 2006 edition was last reviewed and confirmed in 2020 and remains the active International Standard. An earlier edition (1989) was withdrawn and replaced by the 2006 edition.

Q: Is it part of a series?

A: Yes — it is part of the ISO 105 series (Textiles — Tests for colour fastness), which contains many parts addressing colour fastness to light, washing, perspiration, water, chlorine, spotting (acid/alkali/water), adjacent fabrics, and other specific agents.

Q: What are the key keywords?

A: Colour fastness, alkali spotting, textile testing, ISO 105, staining, grey scale, reagent, quality assurance.
