ISO 105-N02-1993 PDF

Full title and description

ISO 105-N02:1993 — Textiles — Tests for colour fastness — Part N02: Colour fastness to bleaching: Peroxide. Specifies a laboratory method to determine the resistance of textile colours to bleaching baths containing hydrogen peroxide at concentrations commonly used in textile processing; the specimen is treated in contact with specified adjacent fabrics and the change in colour and staining are evaluated.

Abstract

Defines a test procedure in which a textile specimen (in contact with one or two adjacent fabrics) is immersed in a peroxide bleaching solution, rinsed and dried; subsequent change in the specimen’s colour and any staining of the adjacent fabric(s) are assessed using the grey scale for colour change and staining.

Scope

This part of ISO 105 specifies a standardized laboratory method to assess how textile colours withstand peroxide bleaching treatments used in textile processing. It applies to textiles of all kinds and in all forms and is intended to provide reproducible conditions for comparing resistance to peroxide-based bleaching and for rating staining of adjacent materials.

Key topics and requirements

• Specified test medium: peroxide-based bleaching bath at concentrations typical for textile processing.
• Specimen preparation and placement in contact with one or two specified adjacent fabrics for staining assessment.
• Controlled immersion, rinsing and drying procedures to ensure repeatability.
• Assessment of change in specimen colour and staining of adjacent fabrics using the grey scale for colour change and staining.
• Instructions to enable comparison between materials, dyes and processing conditions.

Typical use and users

Used by textile testing laboratories, dye manufacturers, fabric and garment producers, quality control departments, research institutions and certification bodies to evaluate and compare the peroxide-bleach fastness of dyed textiles and to check potential staining of adjacent materials during bleaching processes.

Related standards

ISO 105 is a multipart series on tests for colour fastness. Related parts include other N-series methods (for example ISO 105-N01 for hypochlorite bleaching) and numerous ISO 105 parts covering light, washing, rubbing, perspiration and other colour‑fastness tests; users commonly apply several ISO 105 test parts together for a comprehensive colour‑fastness profile.

FAQ

Q: What is this standard?

A: ISO 105-N02:1993 is an ISO test method that specifies how to measure the resistance of textile colours to peroxide bleaching and to assess any staining of adjacent fabrics.

Q: What does it cover?

A: It covers specimen preparation, exposure to a peroxide bleaching bath, rinsing and drying, and evaluation of colour change and staining using the grey scale assessment procedure.

Q: Who typically uses it?

A: Textile test laboratories, dye manufacturers, fabric and garment producers, quality/control departments and research bodies use this standard for routine testing, product development and quality assurance.

Q: Is it current or superseded?

A: The 1993 (Edition 2) publication remains the published edition; it has been subject to ISO’s periodic reviews and has been confirmed in ISO review cycles. For authoritative current status consult the ISO catalogue or your national standards body before citing in formal documentation.

Q: Is it part of a series?

A: Yes — ISO 105 is a multipart series of tests for colour fastness; N02 is one part (peroxide bleaching) among many parts addressing different agents and conditions.
