GOST 9733.27-83 PDF

Full title and description

GOST 9733.27-83 — Textiles. Test method of colour fastness to crocking (Материалы текстильные. Метод испытания устойчивости окраски к трению). The standard defines a laboratory method for assessing the resistance of textile colours to transfer or loss of dye when subjected to friction (dry and wet rubbing) using a rubbing/crocking apparatus.

Abstract

This standard specifies procedures for measuring colour fastness to rubbing (crocking) of textile materials. Test specimens are rubbed under controlled conditions against a specified adjacent (usually white) fabric or rubbing head in dry and wet states; the degree of staining of the adjacent material and/or change in the specimen’s colour is evaluated using a grey-scale or numerical rating to quantify resistance to crocking.

General information

• Status: Originally approved and in use as a USSR GOST textile test method; later usage and replacement vary by jurisdiction — listed as effective historically but noted for replacement by a GOST version of ISO 105‑X12.
• Publication date: Approved by the USSR State Committee for Standards on 17 February 1983; commonly published/issued (printed edition) dated 01 January 1986 in vendor catalogues.
• Publisher: Gosstandart (USSR State Committee for Standards) — national standards body that issued the GOST.
• ICS / categories: 59.080 (Textile and leather technology — textiles in general, including colour fastness).
• Edition / version: Designation GOST 9733.27-83 (year code 1983).
• Number of pages: Approximately 6 pages (standard text length reported by multiple catalogues).

Scope

Applies to textile materials and defines a standardized laboratory method to determine resistance of textile colour to frictional transfer (crocking). The method covers both dry and wet rubbing conditions and the reporting of staining of adjacent fabrics and/or change of colour of the tested specimen. It is used for quality control, specification and comparative testing of dyed and printed textiles.

Key topics and requirements

• Definition of test specimens and conditioning prior to testing.
• Procedures for dry and wet rubbing tests (methods for wetting, number of rubs or cycles as applicable).
• Use of a crocking/rubbing device (crockmeter) and reference to device parameters and loads.
• Evaluation criteria: staining of adjacent fabric and/or colour change of specimen scored by an agreed grey-scale or numerical rating (commonly 1–5 scale in textile practice).
• Reporting requirements: specimen identification, test conditions (dry/wet), instrument type, date and location of test, and numerical/visual results.

Typical use and users

Used by textile manufacturers, dye houses, quality control and testing laboratories, product compliance teams, and procurement/specification engineers to verify colour fastness performance (rubbing/crocking). Also used by equipment suppliers and calibration/validation laboratories that supply or service crockmeters and related test apparatus.

Related standards

Closely related to other parts of the GOST 9733 series (general requirements for colour‑fastness test methods such as GOST 9733.0-83) and to international test methods for rubbing such as ISO 105‑X12 (textiles — tests for colour fastness — colour fastness to rubbing). GOST 9733.27-83 has been referenced alongside and subsequently aligned with GOST/ISO documents; replacement by a national adoption of ISO 105‑X12 (GOST ISO 105‑X12‑2023) is documented in national catalogues.

FAQ

Q: What is this standard?

A: GOST 9733.27-83 is a USSR/Russian GOST standard that specifies a laboratory method for testing the colour fastness of textile materials to friction (crocking), including procedures for dry and wet rubbing tests.

Q: What does it cover?

A: It covers specimen preparation and conditioning, the mechanical rubbing procedure (use of a crocking device), evaluation of staining of adjacent material and/or change in the specimen’s colour, and reporting of results. Both dry and wet rubbing conditions are addressed.

Q: Who typically uses it?

A: Textile manufacturers, dyeing and finishing operations, independent test laboratories, product compliance and specification teams, and equipment manufacturers/suppliers (crockmeters).

Q: Is it current or superseded?

A: Historically in use as a GOST test method; commercial catalogues and normative registries indicate that application on the territory of the Russian Federation is being transitioned to a national adoption of ISO 105‑X12 (published as GOST ISO 105‑X12‑2023) with an indicated cessation date for the older GOST in national listings (see national registry notes). Check the latest national standards registry for authoritative current status and dates.

Q: Is it part of a series?

A: Yes. It is part of the broader GOST 9733 series covering textile test methods and specifically references general requirements defined in related parts (for example GOST 9733.0‑83). It is also conceptually aligned with the ISO 105 series on colour fastness test methods.

Q: What are the key keywords?

A: Colour fastness, crocking, rubbing, textile testing, crockmeter, staining, dry rubbing, wet rubbing, GOST, ISO 105‑X12.
