Full title and description

ISO 105‑S02:1993 — Textiles — Tests for colour fastness — Part S02: Colour fastness to vulcanization: Sulfur monochloride. Specifies a laboratory method to determine the resistance of textile colours (all kinds and forms) to the action of sulfur monochloride vapour under conditions typical of cold vulcanizing of rubber; colour change is assessed using a grey scale after neutralization with ammonium hydroxide.

Abstract

A concise test method for exposing textile specimens to sulfur monochloride vapour and assessing any change in colour and staining. The standard defines specimen preparation, exposure conditions, neutralization (ammonium hydroxide), and visual evaluation using the grey scale for colour change and staining. This method applies to textiles in all forms where resistance to cold vulcanizing agents is required.

Scope

This part of ISO 105 specifies a test to determine how textile colours withstand exposure to sulfur monochloride vapour produced during cold vulcanization of rubber. The procedure covers specimen exposure, neutralization, and visual assessment of colour change and staining (grey scale evaluation). It is intended for use where textiles may be exposed to vulcanizing conditions or where transfer of vulcanizing agents could affect appearance.

Key topics and requirements

• Exposure of textile specimens to sulfur monochloride vapour under defined conditions (replicating cold vulcanizing environments).
• Neutralization step (ammonium hydroxide) after exposure to remove/stop residual reagent prior to evaluation.
• Visual assessment of colour change and staining using standardized grey scales.
• Applicability to textiles of all kinds and in all forms (fabric, finished goods, etc.).
• Requirements for specimen preparation, apparatus, test conditions and evaluation reporting to ensure repeatability.

Typical use and users

Used by textile testing laboratories, dye and finish manufacturers, quality control departments in textile and rubber product industries, test houses performing conformity or performance testing, and standards bodies referencing colour‑fastness methods. It is applied when assessing resistance to vulcanization-related chemicals or when fabrics will be used in close contact with vulcanized rubber components.

Related standards

ISO 105-S02 is one part of the ISO 105 series (tests for colour fastness). Other related parts of ISO 105 cover different agents and conditions (e.g., washing, light, rubbing, solvent spotting). National and regional adoptions and related documents exist (for example EN/DIN/UNE adoptions of ISO 105‑S02). Users often consult neighboring ISO 105 parts when assembling a comprehensive colour‑fastness test program.

FAQ

Q: What is this standard?

A: ISO 105‑S02:1993 is an international test method that specifies how to evaluate the resistance of textile colours to sulfur monochloride vapour encountered during cold vulcanization of rubber.

Q: What does it cover?

A: It covers specimen exposure to sulfur monochloride vapour, subsequent neutralization (with ammonium hydroxide), and visual assessment of colour change and staining using grey scales. It is a short procedural standard intended for reproducible lab testing.

Q: Who typically uses it?

A: Textile test laboratories, manufacturers of dyed/finished textiles, rubber product manufacturers concerned about transfer or exposure, and quality assurance teams that require documented colour‑fastness assessments.

Q: Is it current or superseded?

A: As published in 1993 (Edition 2), ISO 105‑S02 was reviewed and confirmed as the current version in ISO's systematic review process (confirmation noted in 2025), so this edition remains the valid text unless a future revision is published.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 105 series (Tests for colour fastness), which contains multiple parts addressing different agents and conditions affecting textile colour fastness.

Q: What are the key keywords?

A: Colour fastness, vulcanization, sulfur monochloride, textiles, grey scale, ammonium hydroxide, ISO 105, test method.
