Full title and description

ISO 105-Z03:1996 — Textiles — Tests for colour fastness — Part Z03: Intercompatibility of basic dyes for acrylic fibres. Specifies a laboratory method to determine the behaviour of a basic dye with respect to its compatibility with other basic dyes when applied to acrylic fibres, to support assessment of dyeing performance and compatibility in multi-dye formulations.

Abstract

Provides a short, standardized test procedure for assessing the intercompatibility of basic (cationic) dyes on acrylic fibres. The method identifies whether a basic dye, when applied in the presence of other basic dyes, behaves compatibly (i.e., produces acceptable combined shades without adverse migration or staining) and records criteria for evaluation and reporting.

Scope

Defines a concise laboratory procedure to determine the compatibility behaviour of a basic (cationic) dye when applied to acrylic fibres in the presence of other basic dyes. The standard covers the principle, precautions, required apparatus and materials, the stepwise test procedure, methods of assessment/evaluation of results and the content required in the test report. It is intended for quality control, dye development and intercompatibility screening rather than for full-scale production recipe specification.

Key topics and requirements

• Definition of intercompatibility testing for basic dyes on acrylic fibres (purpose and overview).
• Required apparatus, reagents and reference materials for performing the test.
• Step-by-step test procedure for applying dyes in the presence of other basic dyes.
• Evaluation criteria and grading/reporting requirements to record compatibility outcomes.
• Safety and handling notes for reagents and dyes used in the procedure.
• Short form test report content to ensure reproducibility and comparability of results.

Typical use and users

Used by textile dye manufacturers, coloration and formulation chemists, quality-control and testing laboratories, acrylic-fibre producers and research groups concerned with dye compatibility and shade reproducibility. Laboratories use the method for screening candidate basic dyes, troubleshooting cross-dyeing issues, and documenting compatibility for production or regulatory records.

FAQ

Q: What is this standard?

A: ISO 105‑Z03:1996 is an ISO test-method standard that specifies a laboratory procedure for determining the intercompatibility of basic (cationic) dyes applied to acrylic fibres.

Q: What does it cover?

A: It covers the principle of the intercompatibility test, required apparatus and materials, the test procedure, methods for evaluating compatibility results, and the information to be recorded in the test report. The standard is concise and focused specifically on compatibility of basic dyes on acrylic substrates.

Q: Who typically uses it?

A: Textile dye formulators, textile testing and quality-control laboratories, acrylic fibre manufacturers and R&D teams use this standard to screen dyes, verify combined-dye behavior and document compatibility for production and quality assurance.

Q: Is it current or superseded?

A: According to ISO bibliographic records the 1996 edition was reviewed and confirmed (most recently in 2024) and remains the current version rather than being withdrawn or replaced.

Q: Is it part of a series?

A: Yes — ISO 105‑Z03 is one part of the ISO 105 family, the international series of standards for Tests for colour fastness; users often consult ISO 105‑A01 (general principles) and related ISO 105 parts for complementary fastness test methods.
