GOST 9825-73 PDF

Full title and description

ГОСТ 9825-73 — Материалы лакокрасочные. Термины, определения и обозначения (English: Paint materials. Terms, definitions and designations). The standard defines terminology and a system of alphanumeric designations for major paint and varnish materials, including indices that indicate type, film-forming substance and primary application.

Abstract

This GOST establishes common terms, definitions and a structured designation system for main paint and varnish materials (paints, enamels, lacquers, primers, fillers and powder coatings). It specifies the groups of signs used in product codes (type, film-former, intended service conditions, and serial number), as well as indices for variants (for example: Б — solvent‑free, В — water‑dilutable, ВД — water‑dispersion, П — powder). The standard is intended to be applied together with related normative documents for paint terminology and designation practice.

General information

• Status: Listed as an active (действующий) GOST with later reprints and amendments; a revision/replacement project has been initiated (proposal to replace ГОСТ 9825-73 is in development).
• Publication date: Originally approved 27 Feb 1973 and put into effect 01 Jan 1974 (designation year 1973 — GOST 9825-73).
• Publisher: Committee for Standardization and Metrology of the USSR (Gosstandart); printed editions issued by the Publishing House of Standards (Издательство стандартов), Moscow (reprints: e.g. 1991/1992).
• ICS / categories: Paints and varnishes — ICS 87.040 (sometimes indexed in registries as 01.040.87 / 87.040).
• Edition / version: Original 1973 text (effective 1974) with Amendments No.1, No.2, No.3 (approved 1978, 1985, 1989); later reprints/editions (notably a 1991 reissue and editions in collections).
• Number of pages: Varies by printing — typical commercial/library copies list 8–11 pages (common reprints show about 8–9 pages).

Scope

The standard applies to principal paint and varnish materials and prescribes the order and rules for forming product designations according to three main attributes: the kind of material (e.g., enamel, paint, lacquer, primer, powder coating), the chemical nature of the film‑forming substance, and the material’s principal intended application or service conditions (e.g., atmospheric, limited atmospheric, interior). It is intended to be used together with related standards on terminology and technical requirements for coatings.

Key topics and requirements

• Definitions and standardised terminology for main LKM (paint and varnish) product types (paints, enamels, lacquers, primers, fillers, powder coatings).
• Structure of alphanumeric designations: groups of signs specifying type, film‑forming substance (two‑letter codes), application group (numeric), and a serial number; use of indices for variants (e.g., Б, В, ВД, ОД, П).
• Classification of covering materials by intended service conditions (atmospheric, limited atmospheric, interior, etc.).
• Rules for constructing and reading product names (examples: ГФ‑021, ХВ‑113, МА‑025 are shown as illustrative constructions in the standard).
• Cross-references and mandatory joint application with related normative documents (for example, GOST 28246 and later national/regional documents that update specific terminology or methods).
• Provision for amendments and exclusions noted in later changes (three amendments historically recorded).

Typical use and users

Used by paint and varnish manufacturers, formulators, product labelling and marking specialists, quality control and test laboratories, standards and certification bodies, procurement/specification authors, and technical translators. It is referenced in technical documentation, specifications, labelling and product cataloguing where standardised identification of coating materials is required.

Related standards

Key related documents include the predecessor ГОСТ 9825-61, GOST/GOST R series on paint terminology and testing (for example GOST 28246 and its later updates), and international equivalents such as ISO 4618 (Paints and varnishes — Terms and definitions). National modernization projects and draft replacements for ГОСТ 9825-73 have been posted for public discussion to bring designation rules into alignment with current rules (project listings show a planned replacement).

FAQ

Q: What is this standard?

A: ГОСТ 9825-73 is a Soviet / interstate standard titled "Материалы лакокрасочные. Термины, определения и обозначения" (Paint materials — Terms, definitions and designations) that sets terminology and a structured system for designating main paint and varnish materials.

Q: What does it cover?

A: It covers definitions for main LKM types and rules for forming alphanumeric product designations indicating type, chemical nature of the film‑forming substance, intended application group and serial identifiers, plus indices for special varieties (e.g., water‑dilutable, powder, solvent‑free).

Q: Who typically uses it?

A: Paint and varnish producers, quality and compliance laboratories, designers of technical documentation and labels, standards bodies and procurement/specification teams use it to ensure consistent naming and coding of coating products.

Q: Is it current or superseded?

A: The text of ГОСТ 9825-73 (effective 01.01.1974) remains published in national collections and many registries list it as an active standard with historical amendments and reprints; however, modernization work and a public project to replace/update the standard have been initiated (a replacement project for ГОСТ 9825 is in development). Users should check national standards registries or the project status if up‑to‑date compliance with a newer standard is required.

Q: Is it part of a series?

A: Yes — it is part of the body of paint and varnish standards (ICS 87.040) and is linked with related GOSTs on terminology, test methods and technical requirements (for example GOST 28246 and earlier versions such as ГОСТ 9825-61 which it replaced).

Q: What are the key keywords?

A: Paint materials, terms and definitions, designation system, film-forming substances, primers, enamels, lacquers, powder coatings, indices (Б, В, ВД, ОД, П), ICS 87.040.
