Full title and description

ISO 105-B07:2009 — Textiles — Tests for colour fastness — Part B07: Colour fastness to light of textiles wetted with artificial perspiration. This International Standard specifies a laboratory method to determine the resistance of textile colours to the combined effect of wetting with acidic or alkaline artificial perspiration solutions and exposure to an artificial light source representing daylight (D65).

Abstract

ISO 105-B07:2009 defines specimen preparation, artificial perspiration solutions (acidic and alkaline formulations), mounting and exposure procedures under a controlled light source simulating natural daylight (D65), and the procedures for assessing and reporting the change in colour. The test uses reference materials (blue-wool references) and can be assessed visually (grey scale) or instrumentally (spectrophotometer) to provide reproducible lightfastness data for textiles when wetted with perspiration solutions.

Scope

This part of ISO 105 specifies a method for determining the resistance of the colour of textiles (all kinds and forms) to the combined effects of being wetted with artificial perspiration (acidic or alkaline solutions) and exposure to an artificial light source representing daylight (D65). The procedure covers preparation and conditioning of specimens, composition and pH of artificial perspiration solutions, mounting and exposure arrangements, the use of blue-wool reference materials as a fading benchmark, and requirements for evaluation and reporting of results.

Key topics and requirements

• Definition and preparation of artificial perspiration solutions (acidic and alkaline formulations with specified pH and components).
• Specimen size, wet‑pick‑up and mounting requirements (typical minimum specimen dimensions and mounting on non‑fluorescent white cards for exposure).
• Light source and exposure conditions: simulated daylight (D65) artificial light source with controlled irradiance and exposure cycles.
• Use of blue‑wool reference strips (exposed as a benchmark) to define test end‑points and enable reproducible comparison of fading.
• Assessment methods: visual assessment using the ISO grey scale for change in colour or instrumental (spectrophotometric/colorimetric) assessment converted to grey‑scale ratings.
• Reporting requirements: test conditions, solution used (acid/alkaline), exposure time to blue‑wool endpoint, observed/ instrumental colour change results and derived ratings.

Typical use and users

ISO 105-B07:2009 is used by textile test laboratories, R&D groups in textile and apparel manufacturing, quality assurance teams, dye and finish suppliers, and regulatory/testing bodies concerned with product durability and human‑wear performance. It helps manufacturers and testers evaluate how dyes and finishes behave when textiles are exposed to perspiration and daylight, supporting claims for lightfastness in wearable products and technical textiles.

Related standards

ISO 105-B07 is part of the ISO 105 series (Tests for colour fastness). Closely related and commonly referenced standards in the ISO 105 family include ISO 105-A02 (Grey scale for assessing change in colour), ISO 105-A05 (Instrumental assessment of change in colour for determination of grey scale rating), ISO 105-B02/ISO 105-B01 (other colour‑fastness to light/xenon methods), and ISO 105-B08 (quality control of blue wool reference materials). These give complementary procedures for assessment, instrumentation and reference materials.

FAQ

Q: What is this standard?

A: ISO 105-B07:2009 is an ISO test method that defines how to test the colour fastness of textiles to light when the textile is wet with artificial perspiration (acidic or alkaline). It provides a reproducible laboratory procedure for evaluating dye/finish performance under simulated human perspiration plus daylight exposure.

Q: What does it cover?

A: It covers specimen preparation and mounting, the composition and use of artificial perspiration solutions, exposure to an artificial daylight source (D65), use of blue‑wool reference materials to set the endpoint, and visual or instrumental evaluation of the resulting colour change. Results are reported as grey‑scale or instrument‑derived ratings.

Q: Who typically uses it?

A: Textile test laboratories, product development and quality teams in textile and apparel manufacturers, dye/finish formulators, certification bodies and standards organizations use it to assess and document lightfastness performance under perspiration conditions.

Q: Is it current or superseded?

A: ISO 105-B07:2009 is listed as the published edition from 2009 and is recorded in ISO lifecycle information as the active/confirmed publication. National adopted versions (EN ISO, DIN EN ISO, UNE‑EN ISO, etc.) are commonly available and retain equivalence. Users should check with their national standards body or the ISO catalogue for any later amendments or revisions.

Q: Is it part of a series?

A: Yes — it is part of the ISO 105 series, which groups methods for tests for colour fastness (many A, B and C parts). ISO 105-B07 specifically addresses the combination of perspiration wetting and light exposure; other B parts address different light/weathering tests and reference material control.

Q: What are the key keywords?

A: Colour fastness, lightfastness, artificial perspiration, D65, blue‑wool reference, grey scale, textile testing, ISO 105.
