GOST 34042-2016 PDF

Full title and description

GOST 34042-2016 — "Furniture, timber and polymers. The method for determination of sulphur dioxide in the air of climatic chambers". This national (interstate) standard specifies a standardized laboratory method for measuring the release (emission) of sulphur dioxide (SO2) from furniture items, wood-based and polymer-containing materials using controlled climatic (test) chambers.

Abstract

GOST 34042-2016 defines the apparatus, sampling procedure, reagents, calibration, test-chamber requirements, test conditions, calculation and reporting procedures needed to determine SO2 concentration and emission rates from test specimens in climatic chambers. The method applies to chambers with working volumes from about 0.125 m³ up to 50.0 m³ and includes requirements for environmental control and result processing (including calculation of stationary concentration from the last measurements). It is intended for product development, production control and conformity assessment.

Scope

The standard establishes a laboratory test method to determine the release of sulphur dioxide (SO2) from furniture products, furniture parts, wood-composite and polymer-containing materials under controlled climatic conditions. It specifies applicable chamber volumes (0.125–50.0 m³), sample preparation, instrumentation and measurement/reporting rules. The method is recommended for use in conformity assessment (certification, declaration of conformity) and for putting products into production.

Key topics and requirements

• Principle of the method: controlled exposure of specimens in a climatic chamber and quantitative determination of SO2 in chamber air by chemical/analytical sampling and calibration.
• Chamber size and configuration: intended for chambers with working volumes from 0.125 m³ to 50.0 m³ with specified inlet/outlet sampling ports and specimen arrangements.
• Environmental control: defined tolerances for temperature, relative humidity, air exchange and air velocity; monitoring and recording of chamber parameters during tests.
• Sampling and analysis: requirements for sampling devices, reagents, blank (background) checks, calibration (calibration graph or coefficients) and calculation of mass/concentration (mg/m³).
• Data treatment: computation of concentration corrected to reference temperature/pressure, use of the last measurements to calculate stationary concentration (averaging last four values under specified acceptance criteria).
• Reporting: required contents for a test report (sample description, chamber conditions, calibration data, measured values, computed stationary concentration, test duration and signatures).

Typical use and users

Primary users include testing and calibration laboratories, furniture and wood-product manufacturers, polymer-material producers, certification bodies and regulatory agencies concerned with indoor air quality and product emissions. The method is applied during product development, pre-production qualification, type testing for certification and quality control to verify SO2 emissions from materials and finished items.

Related standards

GOST 34042-2016 is used alongside other national and international methods for gas/air analysis and emissions testing. Related documents include ambient-air SO2 methods (e.g., GOST R 52733‑2007 — ultraviolet fluorescence method for ambient SO2), food/product SO2 determination methods and chamber-testing standards and guidance for emissions (for example, ISO/EN test-chamber methods for indoor air and building-product emissions such as parts of ISO 16000/EN standards). National GOST catalogs and standard bibliographies list these cross-references.
