Full title and description

ISO 105-A06:1995 — Textiles — Tests for colour fastness — Part A06: Instrumental determination of 1/1 standard depth of colour. This part of ISO 105 specifies a colour‑metric (instrumental) procedure intended as an alternative to the visual method for determining the 1/1 standard depth of a dyeing on textile materials.

Abstract

The standard provides an instrumental (colorimetric) method for determining the 1/1 standard depth of colour of a dyeing on any textile material. It is intended as a permitted alternative to the visual comparison procedure described in clause 12 of ISO 105‑A01:1994; its application is restricted to the 1/1 standard depth and use for other depths was under consideration when published. The method notes that results may differ from visual assessments and recommends stating the evaluation method in subsequent test reports.

• Number of pages: 4 pages (official ISO bibliographic entry lists 4 pages for the English edition).

Scope

This part of ISO 105 specifies a colour‑measurement (instrumental) procedure for determining whether a dyed textile specimen has the 1/1 standard depth of colour. It is applicable to dyeings on any textile material but is limited to the 1/1 standard depth; it is intended as an alternative to the visual comparison procedure given in ISO 105‑A01:1994 and users are advised to record which evaluation method was used because instrumental and visual determinations may not always agree.

Key topics and requirements

• Definition of the 1/1 standard depth of colour and its significance in colour‑fastness testing.
• Procedure for instrumental (colorimetric) measurement to determine 1/1 standard depth as an alternative to visual matching.
• Requirements for instrumentation, measurement geometry and calculation of the relevant colour coordinates or indices.
• Notes on comparability with visual methods and recommendation to report the method used in subsequent test reports.

Typical use and users

Laboratories performing textile colour‑fastness testing, textile manufacturers, dye houses, quality control teams and standards bodies use ISO 105‑A06 when an instrumental determination of the 1/1 standard depth is required or preferred. It is most useful where objective, instrument‑based assessment is needed instead of subjective visual matching (for example, in automated test workflows or where traceable numeric records are required).

Related standards

ISO 105‑A06 is part of the ISO 105 series (Tests for colour fastness). It is related to ISO 105‑A01:1994 (visual method for determination of standard depth) and other ISO 105 parts that specify colour‑fastness test methods and evaluation procedures. Several national/European adoptions exist (for example EN/ISO adoptions such as EN ISO 105‑A06 published in the late 1990s), which reproduce this ISO part as a regional standard.

FAQ

Q: What is this standard?

A: ISO 105‑A06:1995 is an ISO standard that specifies an instrumental (colorimetric) method for determining the 1/1 standard depth of colour of a dyeing on textile materials; it is part A06 of the ISO 105 series on tests for colour fastness.

Q: What does it cover?

A: It covers a permitted instrumental alternative to the visual 1/1 depth assessment described in ISO 105‑A01:1994, including measurement procedure basics, instrumentation considerations and notes on comparability with visual methods. The method is specifically limited to the 1/1 standard depth.

Q: Who typically uses it?

A: Textile test laboratories, manufacturers, dye houses, QA/QC personnel and conformity assessment bodies that need objective, instrument‑based assessment of standard depth of colour use this standard.

Q: Is it current or superseded?

A: The ISO bibliographic entry shows ISO 105‑A06:1995 as published in December 1995 and indicates it was reviewed and confirmed in ISO’s review cycle (the ISO entry notes confirmation in the 2023 review), so the 1995 edition remains the current published version unless a later revision has been published after that review. Users requiring the very latest status should check the ISO catalogue or their national standards body for any amendments or replacement documents issued after 2023.

Q: Is it part of a series?

A: Yes — it is part of the ISO 105 series (Tests for colour fastness), which comprises multiple parts (A, B, C, etc.) covering general methods (A), specific test methods (B and others) and evaluation procedures for textile colour‑fastness.

Q: What are the key keywords?

A: Key keywords include: colour fastness, colorimetry, 1/1 standard depth, textile dyeing, ISO 105, instrumental determination, visual comparison alternative.
