Textiles - Tests for colour fastness - Part E06: Colour fastness to spotting: Alkali (ISO 105-E06:2006)

ISO 105-E06:2006 specifies a method for determining the resistance of the colour of textiles of all kinds, and in all forms, to the action of dilute alkaline solutions.
Three tests differing in severity are provided. Any or all may be used, depending on the nature of the fibre.

Dieser Teil von ISO 105 legt ein Prüfverfahren zur Bestimmung der Widerstandsfähigkeit der Farbe von Textilien jeder Art und in allen Verarbeitungszuständen gegen das Einwirken von verdünnten Alkalilösungen fest.
Es sind drei Prüfungen mit verschieden starker Beanspruchung vorgesehen. In Abhängigkeit von der Art der Faser können eine oder alle Prüfungen angewendet werden.

Overview

EN ISO 105-E06:2006 - Textiles: Tests for colour fastness - Part E06: Colour fastness to spotting: Alkali (ISO 105-E06:2006) specifies a standardized laboratory method to evaluate how textile colours resist contact with dilute alkaline solutions. The method covers textiles in all forms (fabric, yarn, loose fibre) and provides three test severities so laboratories and manufacturers can choose the appropriate alkali challenge for the fibre type and end‑use.

Key topics and requirements

• Three alkali tests:
  • Sodium carbonate solution (Na2CO3) - mild alkaline spotting.
  • Calcium hydroxide paste (Ca(OH)2) - moderate severity.
  • Ammonium hydroxide solution (NH4OH) - highest severity (specimens steeped for 2 minutes).
• Sample preparation: typical specimen size for fabric is 40 mm × 100 mm. Yarn and loose fibre procedures are also described (knitted fabric specimen or wick; compressed sheet for fibres).
• Application method: spotting with a pipette/dropper and working in with a glass rod for carbonate and hydroxide paste; steeping for ammonium hydroxide. Drying and removal of residues by brushing or rinsing (Grade 3 water) are specified.
• Assessment: colour change is assessed visually using the grey scale (ISO 105‑A02) or instrumentally (ISO 105‑A05). Wet-spot assessment after 10 minutes is included where relevant.
• Reporting: test reports must reference EN ISO 105‑E06:2006 and include sample identification, numerical grey-scale or instrumental ratings for each alkali, wet-change results (if measured), water-spotting resistance (see ISO 105‑E07), and any deviations from the procedure.
• pH guidance: the standard lists typical pH ranges for the reagents (e.g., ammonium hydroxide pH 13.5–13.7; calcium hydroxide pH 12.3–12.5; sodium carbonate pH 11.5–11.7).

Applications

• Quality control for dyed and printed textiles to ensure resistance to alkaline spotting during manufacturing, laundering or end‑use.
• Validation of dye and finishing processes by textile mills, dyehouses and OEMs.
• Routine or acceptance testing in textile testing laboratories and certification bodies.
• Material selection for products exposed to alkaline environments (industrial workwear, medical textiles, household textiles).

Who uses this standard

• Textile manufacturers and converters
• Dyeing and finishing laboratories
• Independent textile test laboratories and certifiers
• R&D teams developing dyes, finishes and colourants
• Quality assurance personnel in apparel, home textile and technical textile sectors

Related standards

• ISO 105‑A01 (general principles)
• ISO 105‑A02 (grey scale for assessing change)
• ISO 105‑A05 (instrumental assessment)
• ISO 105‑E07 (colour fastness to spotting: water)

EN ISO 105‑E06:2006 is essential for consistent, reproducible assessment of alkali-induced colour damage and supports product quality, compliance and material selection in the textile 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. Each 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the membe
