GOST 9733.3-83 PDF

Full title and description

GOST 9733.3-83 — Textiles. Test method of colour fastness to artificial light (xenon lamp). Russian title: «Материалы текстильные. Метод испытания устойчивости окраски к свету в условиях искусственного освещения (ксеноновая лампа)». The standard specifies a xenon-arc exposure test procedure for assessing the resistance of textile colours to artificial light.

Abstract

This standard defines a laboratory method using a xenon-arc lamp to simulate the effect of daylight/artificial illumination on dyed and printed textile materials and to evaluate changes in colour and staining. It provides requirements for apparatus, specimen preparation, exposure conditions, assessment procedures and reporting of results. The method is aligned with the corresponding ISO test method.

General information

• Status: Originally adopted by the USSR as an interstate standard; catalogues and standards libraries show mixed status — many commercial repositories list it as in force while some national catalogues indicate it has been withdrawn or superseded in specific jurisdictions.
• Publication date: Approved 1983 (Decree of the State Committee for Standards dated 17 Feb 1983); recorded in catalogs with effective/publication date 1 January 1986.
• Publisher: Interstate (USSR) standards body / Gosstandart (interstate standard, МЕЖГОСУДАРСТВЕННЫЙ СТАНДАРТ).
• ICS / categories: 59.080.01 — Textiles in general (textile testing methods).
• Edition / version: Designation GOST 9733.3-83 (1983 edition / series part 3).
• Number of pages: Approximately 14 pages (typical commercial copies list 14 pages).

Scope

Applies to textile materials of any fibre composition and class of dyes where assessment of colour fastness to light is required. The standard specifies a laboratory procedure using a xenon-arc lamp to reproduce the effect of daylight and artificial illumination and to permit comparative evaluation of colour change and staining after specified exposure cycles. It is intended for use where a controlled, reproducible artificial-light exposure is needed for quality control, specification or research.

Key topics and requirements

• Test principle: exposure of specimens to xenon-arc illumination that simulates natural daylight.
• Apparatus: xenon-arc lamp test chamber with specified filters, irradiance control, temperature and humidity monitoring and specimen holders.
• Specimen preparation: instructions for cutting, mounting, pairing (for staining assessment) and conditioning of specimens before test.
• Exposure conditions: defined irradiance, black-panel temperature or chamber temperature, exposure cycle duration and sequence of light/dark or water spray cycles as applicable.
• Evaluation: visual assessment of colour change and staining using grey scales or specified comparison methods; recording of ISO-equivalent rating scales where applicable.
• Reporting: required test parameters, specimen descriptions, exposure results and any deviations from the standard procedure.
• Equivalence/relationship to ISO: the method corresponds to ISO test methods for colour fastness to light (notably the ISO 105-B02 family), and the GOST text identifies this relationship.

Typical use and users

Used by textile manufacturers, dye and finish producers, independent testing laboratories, quality control and R&D departments, standards organizations and procurement/specification teams who need controlled assessment of colour fastness to light for fabrics, garments and related textile products. It is commonly applied in product development, incoming quality control and compliance testing.

FAQ

Q: What is this standard?

A: GOST 9733.3-83 is a Soviet/Interstate standard that specifies a laboratory test method using a xenon-arc lamp to evaluate the colour fastness of textile materials to artificial light.

Q: What does it cover?

A: It covers apparatus requirements, specimen preparation, exposure conditions, assessment procedures (for colour change and staining) and reporting for xenon-arc lightfastness testing of textiles. The method is aligned with corresponding ISO lightfastness procedures.

Q: Who typically uses it?

A: Textile manufacturers, dye and finish suppliers, independent test laboratories, product developers, quality assurance teams and standards organizations involved in textile performance testing.

Q: Is it current or superseded?

A: The original designation dates from 1983 with an effective/catalog publication date commonly listed as 1 January 1986. Commercial standards libraries often list the document as active; however, some national catalogues and standardization bodies have withdrawn or replaced it with newer ISO/EN methods in their jurisdictions. Users should check the current status with their national standards body before relying on it for regulatory or contractual purposes.

Q: Is it part of a series?

A: Yes — it is part of the GOST 9733 series of standards on textile colour fastness testing (for example GOST 9733.0-83 and other 9733.x parts covering different test actions and general requirements).

Q: What are the key keywords?
