ISO 105-E07-2010 PDF

Full title and description

ISO 105‑E07:2010 — Textiles — Tests for colour fastness — Part E07: Colour fastness to spotting: Water. Specifies a laboratory method for assessing the resistance of textile colours (all kinds and forms) to spotting by water, including procedures for applying water drops to specimens and for assessing colour change and staining.

Abstract

ISO 105‑E07:2010 defines a simple, reproducible test in which drops of water are worked into the textile specimen (commonly with a glass rod) and the resulting change in colour of the specimen and any staining of adjacent fabrics is assessed, typically using the ISO grey scale, after two minutes and again after drying. The method provides a standardised way to evaluate susceptibility to water spotting across fibres, constructions and colourants.

Scope

This part of ISO 105 specifies a method for determining the resistance of the colour of textiles of all kinds and in all forms to spotting by water. The scope covers preparation of specimens, apparatus and reagents required, test procedure (application of water drops and treatment of the specimen), assessment criteria (visual grey scale or instrumental assessment), and reporting of results. The method is intended for laboratory assessment and quality-control testing rather than direct prediction of in-service behaviour under all real-world conditions.

Key topics and requirements

• Purpose: determine resistance of textile colour to water spotting.
• Specimen preparation: conditioning, dimensions and mounting of samples for testing.
• Apparatus and reagents: provision for glass rod or equivalent applicator, standard water quality, conditioning cabinet and grey scale for assessment.
• Test procedure: application of measured drops of water worked into the specimen, exposure for specified time (assessment after ~2 minutes) and repeated assessment after drying.
• Assessment methods: grey scale for change in colour and for staining of adjacent fabrics; option for instrumental measurement where appropriate.
• Reporting: test conditions, specimen identification, number of drops, assessment times, results (grey‑scale grades) and any deviations from the procedure.

Typical use and users

Used by textile test laboratories, research and development departments, fabric and garment manufacturers, quality assurance and inspection teams, retail technical services and certification bodies. Typical applications include incoming raw-material checks, production quality control, product development (dyeing and finishing evaluation) and dispute resolution where water spotting is a concern (e.g., upholstery, outerwear, technical textiles).

FAQ

Q: What is this standard?

A: ISO 105‑E07:2010 is an international standard that specifies a laboratory test method to assess the resistance of textile colours to spotting by water.

Q: What does it cover?

A: It covers specimen preparation, apparatus and reagents, the procedure for applying and working water onto the specimen, timings for assessment (after ~2 minutes and after drying), criteria for evaluation (visual grey scale or instrumental methods) and reporting requirements.

Q: Who typically uses it?

A: Textile test laboratories, R&D and quality control teams in textile and apparel manufacturing, retailers’ technical services, and conformity assessment bodies use this test to evaluate and document water‑spotting behaviour.

Q: Is it current or superseded?

A: The edition shown here was published in April 2010 (Edition 4). The ISO record notes this edition was reviewed and confirmed (last confirmation) in 2020; it remained published following that review. Users should check with the national or international standards body for any later revisions or confirmations beyond 2020 before assuming current applicability.

Q: Is it part of a series?

A: Yes. ISO 105 is a multipart series of standards (Textiles — Tests for colour fastness) covering many specific agents and conditions; ISO 105‑E07 is one part focused on water spotting and is intended to be used alongside the general guidance in ISO 105‑A01 and other relevant ISO 105 parts.

Q: What are the key keywords?

A: Colour fastness, spotting, water, textiles, ISO 105, grey scale, test method, ISO/TC 38.
