Full title and description

ISO 105-E08:1994 — Textiles — Tests for colour fastness — Part E08: Colour fastness to hot water. This international standard specifies a laboratory method (available in PDF and print) for assessing the change in colour of textiles and the staining of adjacent fabrics after exposure to hot water; the procedure is commonly applied to wool and wool-blend textiles.

Abstract

A specimen of the textile, in contact with adjacent fabrics, is rolled around a glass rod, treated with slightly acidified hot water and dried. After treatment the change in colour of each specimen and the staining of the adjacent fabrics are assessed using the standard grey scales. The method is primarily intended for wool and textiles containing wool.

Scope

This part of ISO 105 specifies a test method to determine the resistance of dyes on textiles of all kinds and in all states of manufacture to the action of hot water. Although applicable to a wide range of textile types, the procedure is particularly suited to wool and wool-containing materials; it evaluates both colour change of the test specimen and staining of adjacent undyed fabrics.

Key topics and requirements

• Specimen assembly: the test specimen is placed in contact with specified adjacent fabrics and rolled around a glass rod.
• Treatment medium: slightly acidified hot water is used to simulate exposure to hot-water conditions.
• Apparatus: a reflux arrangement (to avoid loss of water), thermostatically controlled bath and glass rod are typical required items.
• Typical test conditions recorded in practical references include treatment at about 70 °C with reflux for a set period (commonly documented as 30 minutes) — followed by drying and assessment.
• Assessment: change in colour of the specimen and staining of adjacent fabrics are rated using the standard grey scales for colour change and staining.
• Reporting: test reports should identify the standard, sample identification, test conditions used, and grey-scale ratings for colour change and staining.

Typical use and users

Laboratories, textile manufacturers, dye houses, quality assurance teams and regulatory bodies use this standard to evaluate colour fastness performance of wool and wool-blend textiles under hot-water exposure. It is used for product development, incoming material inspection and comparative quality control.

Related standards

ISO 105-E08 is one part of the broader ISO 105 series (tests for colour fastness), which includes many related parts covering water, sea water, chlorinated water, perspiration, rubbing, washing, steaming, bleaching and adjacent-fabric specifications. Companion parts that define adjacent fabrics (F series) and other E-series methods are commonly used together with E08.

FAQ

Q: What is this standard?

A: ISO 105-E08:1994 is the ISO test method titled "Textiles — Tests for colour fastness — Part E08: Colour fastness to hot water" that specifies a laboratory procedure to assess colour change and staining after exposure to hot water.

Q: What does it cover?

A: It covers the preparation of specimen/adjacent-fabric assemblies, treatment of specimens in slightly acidified hot water under reflux, drying and evaluation of both change in colour and staining of adjacent fabrics using grey scales.

Q: Who typically uses it?

A: Test laboratories, textile and apparel manufacturers, dye houses, quality control and R&D departments, and conformity assessment bodies concerned with the colour fastness of wool and wool-containing textiles.

Q: Is it current or superseded?

A: The 1994 edition (Edition 3) is the published version. According to ISO records this edition was last reviewed and confirmed (i.e., kept current) as part of ISO’s systematic review process (confirmed in 2020). Users should confirm the current status from ISO or national standards bodies before use.

Q: Is it part of a series?

A: Yes — ISO 105-E08 is one part of the ISO 105 series (Tests for colour fastness), which contains multiple E‑parts addressing different wet- and dry-exposure conditions as well as F‑parts that specify standard adjacent fabrics.

Q: What are the key keywords?

A: Colour fastness; hot water; wool; grey scales; adjacent fabric; ISO 105; dye fastness; reflux; textile testing.
