Full title and description

ISO 105-J01:1997 — Textiles — Tests for colour fastness — Part J01: General principles for measurement of surface colour. This part of ISO 105 is a reference document that explains how to measure the colour of textile specimens by instrumental means (spectrophotometer or colorimeter) and describes general concepts and problems associated with reflectance colour measurement; Annex A gives techniques and specimen‑handling procedures.

Abstract

Provides general principles and guidance for the instrumental measurement of surface colour of textile specimens. Topics include definitions (reflectance, fluorescence, colourimetric values), instrument types and geometries (diffuse/0, 0/diffuse, 45/0), calibration and control standards, specimen presentation and handling, measurement procedure and calculation of colour values from spectral data or tristimulus values. Annex A is integral and specifies practical specimen‑handling and measurement techniques.

Scope

This part of ISO 105 is intended as a reference to support the correct instrumental measurement of the colour of textile specimens as required by many other parts of the ISO 105 series. It addresses reflectance‑based measurements in the visible spectral region, instrument geometries, calibration and verification procedures, specimen preparation and presentation, and the basic calculations needed to derive colourimetric values from spectral or tristimulus data. Annex A gives specific measurement techniques and handling procedures for textile test specimens.

Key topics and requirements

• Definitions of colour measurement terms (colourimetric value, reflectance, fluorescence, specular/diffuse reflection).
• Instrument types: spectrophotometers (spectral reflectance factors) and colorimeters (tristimulus values) and their appropriate use.
• Measurement geometries and their effects (d/0, 0/d, 45/0 and circumferential vs directional arrangements).
• Calibration and verification: use of white and (where required) black/gray standards and maintenance of calibration records.
• Specimen collection, conditioning and presentation; special handling techniques detailed in Annex A to ensure reproducible readings.
• Procedure steps: standardize instrument, present specimen, record spectral reflectance or tristimulus values, calculate colourimetric coordinates and differences as required by the test application.
• Considerations for fluorescence, surface texture, specular component inclusion/exclusion and averaging over multiple measurements or specimen areas.

Typical use and users

Used by textile test laboratories, quality‑control and colour‑matching teams in textile and apparel manufacturing, research laboratories, standards bodies and conformity assessment organizations. It supports other ISO 105 test parts that require objective colour measurement as part of colour‑fastness testing and routine quality control.

Related standards

Other parts of the ISO 105 series (textile colour fastness tests and supporting documents), and general colorimetry/colour‑measurement standards such as ISO 7724 and related CIE/ISO colorimetry publications (standards covering colour measurement principles, observers and illuminants, and colour‑difference calculations). National/adopted versions (EN, ÖNORM, etc.) may be published under the same designation.

FAQ

Q: What is this standard?

A: ISO 105-J01:1997 is the part of the ISO 105 series that gives general principles for instrumental measurement of surface colour on textile specimens; it serves as a reference for other ISO 105 test parts.

Q: What does it cover?

A: It covers definitions, instrument types, measurement geometries, calibration/verification, specimen preparation and presentation, the measurement procedure (spectral reflectance or tristimulus measurement) and calculation of colour values; Annex A contains practical specimen‑handling and measurement techniques.

Q: Who typically uses it?

A: Textile testing laboratories, manufacturers and quality control teams, colour‑matching specialists, research institutes and standards/conformity bodies that perform or specify instrumental colour measurement for textiles.

Q: Is it current or superseded?

A: The 1997 edition (Edition 4) remains the published version; it was last reviewed and confirmed by ISO in 2024 and therefore remains current (confirmed after periodic review). Users should check for any national or sectoral adoptions or subsequent revisions before assuming longer‑term applicability.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 105 series (textiles — tests for colour fastness). Many other parts of ISO 105 cover specific fastness tests and reference J01 for colour‑measurement practice.

Q: What are the key keywords?

A: Colour measurement, reflectance, spectrophotometer, colorimeter, measurement geometry (d/0, 45/0), calibration, specimen handling, ISO 105.
