ISO 105-A05:1996/Cor 1:1997 — Textiles — Tests for colour fastness — Part A05: Instrumental assessment of change in colour for determination of grey scale rating — Technical Corrigendum 1 (PDF). This corrigendum contains a small number of technical amendments and clarifications to the original ISO 105‑A05:1996 instrumental-method text, and is published as a one‑page technical rectification to the 1996 edition.

Abstract

This technical corrigendum corrects and clarifies minor items in ISO 105‑A05:1996 concerning the instrumental assessment method used to determine a grey scale rating from measured colour change. It does not introduce a new test method but modifies the published 1996 text to remove errors or ambiguous wording.

General information

Scope

This corrigendum applies specifically to ISO 105‑A05:1996 and is limited to technical corrections and editorial clarifications relevant to the instrumental procedure for assessing change in colour and the calculations used to convert instrumental measurements to a grey scale rating. It does not replace the main method but amends the published text where needed.

Key topics and requirements

• Instrumental assessment method for measuring change in colour of a test specimen relative to an untreated reference.
• Calculation procedure to convert instrumental colour-difference measurements into an equivalent grey scale rating.
• Corrections/clarifications to the original normative text (minor amendments only).
• Applicability as a technical corrigendum (i.e., concise amendment rather than a full revision).

Typical use and users

Used by textile testing laboratories, quality-control personnel in textile and apparel manufacturing, instrument manufacturers (colour measurement equipment), standards bodies and accreditation/inspection organizations that perform or interpret colour‑fastness testing and grey scale assessments. The corrigendum is applied when testers reference ISO 105‑A05:1996 to ensure they use the corrected wording or calculation steps.

FAQ

Q: What is this standard?

A: It is ISO 105‑A05:1996/Cor 1:1997 — a one‑page technical corrigendum that makes minor corrections and clarifications to the ISO 105‑A05:1996 method for instrumental assessment of change in colour used to determine a grey scale rating.

Q: What does it cover?

A: It covers technical corrections to the published instrumental assessment method and the calculations that convert instrumental measurements into an equivalent grey scale rating; it does not introduce a new test method.

Q: Who typically uses it?

A: Textile test laboratories, manufacturers and quality control teams, instrument suppliers and standards/ accreditation bodies that perform or interpret colour‑fastness and grey‑scale assessments.

Q: Is it current or superseded?

A: The corrigendum was published in February 1997 to amend the 1996 edition. The ISO 105‑A05:1996 main document and its corrigenda have been maintained by ISO; the base standard was reviewed and confirmed in recent ISO reviews. Users should refer to the ISO catalogue entry for the latest confirmation/withdrawal status and any further corrigenda or revisions.

Q: Is it part of a series?

A: Yes — it is part of the ISO 105 series (Tests for colour fastness), a multi‑part suite covering general principles, grey scale methods, instrumental assessments and many specific colour‑fastness test methods. See ISO 105‑A01 for a listing of related parts.
