Full title and description

ISO 105-S01:1993 — Textiles — Tests for colour fastness — Part S01: Colour fastness to vulcanization: Hot air. Specifies a standardized laboratory method for determining the resistance of textile colour to the action of a typical unvulcanized rubber compound and its decomposition products during hot‑air vulcanization; colour change is assessed using the ISO grey scale.

Abstract

This part of ISO 105 prescribes a method in which a textile specimen is placed in direct contact with an initially unvulcanized rubber compound and heated in hot air to simulate vulcanization conditions. The test evaluates change in colour (staining and/or change of the specimen) using the ISO grey scale to quantify colour fastness to vulcanization by hot air.

• Edition / version: Edition 2 (1993).
• Number of pages: Short publication — 2 pages (ISO catalogue entry).

Scope

Applies to textiles of all kinds and in all forms (fabrics, dyed yarns, loose fibres, etc.) and defines a laboratory procedure to assess resistance of colour to exposure to a representative rubber compound during vulcanization in hot air; intended to evaluate both direct colour change of the specimen and staining from the rubber compound or its decomposition products.

Key topics and requirements

• Preparation of specimen and contact with an initially unvulcanized rubber compound under controlled hot‑air vulcanization conditions.
• Specified temperature and time conditions for hot‑air exposure to simulate industrial vulcanization.
• Assessment of colour change and staining using the ISO grey scale (numerical grading of change).
• Applicability to a wide range of textile constructions and dye types; guidance on interpretation of results for quality control and material selection.

Typical use and users

Used by textile test laboratories, textile and chemical R&D, quality assurance teams in textile manufacturing, rubber/coating/proofing manufacturers, and regulatory/standards practitioners to verify that textiles retain acceptable colour when exposed to rubber vulcanization processes (e.g., in waterproofing/proofing operations). Useful for suppliers and purchasers specifying colour fastness requirements in procurement and compliance documents.

Related standards

Part of the ISO 105 series (tests for colour fastness) — many companion parts address other agents and procedures (e.g., ISO 105‑C, ISO 105‑X, etc.). ISO 105‑S (1978) was an earlier item addressing colour fastness to vulcanizing; ISO 105‑S01:1993 supersedes that earlier version. Several regional adoptions (EN/UNE/ÖNORM adaptations) exist that reproduce ISO 105‑S01 for use in national/regional markets.

FAQ

Q: What is this standard?

A: ISO 105‑S01:1993 is an international standard that specifies a laboratory test method to evaluate colour fastness of textiles to vulcanization in hot air (contact with an unvulcanized rubber compound).

Q: What does it cover?

A: It covers specimen preparation, exposure of textile specimens in direct contact with a rubber compound under defined hot‑air vulcanization conditions, and assessment of colour change and staining using the ISO grey scale. It is intended for textiles of all kinds.

Q: Who typically uses it?

A: Textile testing labs, manufacturers of textiles and proofing/coating products, quality control and R&D personnel, and procurement/specification writers who need to ensure acceptable colour performance when textiles are exposed to rubber vulcanization processes.

Q: Is it current or superseded?

A: The ISO catalogue shows ISO 105‑S01:1993 as a published international standard (Edition 2, 1993). The entry indicates the standard has been subject to periodic review and has been confirmed (i.e., retained as current following review cycles). Users should check the ISO catalogue or national standards bodies for any more recent amendments or replacements before relying on it for regulatory compliance.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 105 series (Tests for colour fastness), which comprises multiple parts that address different agents and test methods for assessing colour fastness of textiles.

Q: What are the key keywords?

A: Colour fastness, vulcanization, hot air, rubber compound, ISO 105, textile testing, grey scale, staining.
