Full title and description

St ISO 3251-1974 rus — Russian-language edition/translation of ISO 3251:1974, "Paint media — Determination of volatile and non-volatile matter". Specifies a short test method for determining the volatile and non‑volatile content of paint media, commonly issued as a 1974 ISO publication and available in Russian translation under the label "St ISO 3251-1974 rus".

Abstract

This standard defines a gravimetric procedure to determine the amounts of volatile and non‑volatile matter in paint media (binders, paint liquids and similar materials) by controlled drying or evaporation and subsequent weighing. The 1974 edition is a concise two‑page method intended for routine quality control and formulation checks.

General information

• Status: Withdrawn / superseded.
• Publication date: 1974 (published November 1974, Edition 1).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 87.060.20 (Binders; paints and varnishes testing).
• Edition / version: Edition 1 (1974).
• Number of pages: 2 pages (short method sheet).

Scope

Applies to paint media and related binder solutions to determine by mass the fraction of volatile matter removed under defined drying conditions and the complementary non‑volatile residue. The method is intended for routine laboratory quality control and for specifying product composition where volatile content is a relevant parameter. The 1974 text gives the principle, apparatus, sample preparation, drying/evaporation conditions, calculation and reporting format.

Key topics and requirements

• Definition of volatile and non‑volatile matter for paint media and binders.
• Specified apparatus — weighing balance, drying oven or controlled evaporation dish and desiccator.
• Sample quantity, preparation and recommended drying/evaporation temperature and time (as defined in the method) to ensure reproducible mass loss measurement.
• Calculation of volatile and non‑volatile content by mass and required reporting details (sample identification, test conditions, results expressed as percentage by mass).
• Notes on method limitations and suitability for different types of binders and solvent systems (users advised to consult later revisions for expanded guidance).

Typical use and users

Used by paint and varnish manufacturers, binder producers, formulation chemists, quality control and testing laboratories, and regulatory or procurement bodies requiring a standardized measure of volatile and non‑volatile content in paint media. The short 1974 method is practical for routine QC but many laboratories now follow later revisions for broader applicability.

Related standards

ISO 3251:1974 was later revised and expanded in subsequent editions — notably ISO 3251:1993 (revised method for paints, varnishes and binders) and newer revisions (a later 2019 version is available). Users seeking current test requirements should consult the later ISO 3251 editions.

FAQ

Q: What is this standard?

A: ISO 3251:1974 (issued here as St ISO 3251-1974 rus for the Russian version) is an ISO test method that specifies how to determine volatile and non‑volatile matter in paint media by gravimetric means.

Q: What does it cover?

A: It covers the principle, apparatus, sample preparation, drying/evaporation conditions, calculation and reporting for measuring volatile and non‑volatile content of paints, varnishes and binder solutions. The 1974 edition is brief and intended for routine laboratory work.

Q: Who typically uses it?

A: Paint and varnish manufacturers, binder producers, QC and testing laboratories, formulation chemists and purchasers specifying product composition or compliance.

Q: Is it current or superseded?

A: It has been withdrawn and superseded by later editions (ISO 3251:1993 and further revisions, with a newer version referenced as ISO 3251:2019). Users requiring a current normative method should consult the latest ISO 3251 edition.

Q: Is it part of a series?

A: Yes — ISO 3251 belongs to the family of ISO methods for paints and varnishes (ISO/TC 35). The number indicates this specific method; related test methods for paints and binders are published under neighboring ISO numbers and later revisions expand the scope.

Q: What are the key keywords?

A: Paint media, volatile matter, non‑volatile matter, gravimetric method, binder, paint testing, QC, ISO 3251.
