GOST 9.032-74 PDF

Full title and description

GOST 9.032-74 — "Unified system of corrosion and ageing protection. Paint coatings. Groups, technical requirements and designations." The standard classifies paint and lacquer coatings into groups by purpose and operating conditions, sets technical quality requirements and defect limits, and defines designation rules for coatings used on products and structures.

Abstract

GOST 9.032-74 is a national (interstate) standard originally introduced in the USSR that provides a classification scheme for lacquers and paints, detailed technical requirements and defect tolerances for different classes of coatings, and a standardized system for designating coatings. It includes informative and normative appendices covering surface preparation, permissible surface roughness, gloss requirements, methods for determining gloss and defects, and profilometric evaluation of texture. The standard was amended several times (1976, 1980, 1986, 1989) during its lifetime.

• Number of pages: Typically published in short form (around 13–15 pages in commercial reproductions); common catalogue listings show 15 pages.

Scope

The standard applies to lacquer and paint coatings applied to product surfaces and establishes: grouping of coatings by functional purpose and exposure conditions (atmospheric, water-resistant, chemical-resistant, oil/gasoline resistant, thermally resistant, electrical, etc.); technical requirements and defect limits for coating classes (gloss, texture, inclusions, runs, scratches, waviness, etc.); and rules for marking and designating coatings. It is intended to harmonize coating specification and acceptance across industries covered by the unified corrosion- and ageing-protection system.

Key topics and requirements

• Classification of coatings into operational groups (atmospheric, water‑resistant, marine, chemical, oil/benzine resistant, thermoresistant, electrical insulating/conductive, special exposures).
• Technical requirements and defect tolerance tables for coating classes (acceptable numbers/sizes of inclusions, allowable runs, texture and gloss classes, waviness limits, etc.).
• Designation and marking rules for identifying coating type, group and exposure class in documentation and on products.
• Appendices covering surface preparation requirements for painted metal substrates, target roughness values after primer/filler, gloss classification and methods for measuring gloss and coating defects, and profilometric evaluation of texture.
• Cross-references and alignment with other documents from the Unified System of Corrosion and Ageing Protection (examples: GOST 9.104 series and other companion GOSTs on coating selection and testing).

Typical use and users

Used by coatings and paint manufacturers, product designers and materials engineers, quality and inspection personnel, maintenance and asset managers, and standards/specification writers who need a consistent system for selecting, describing and accepting paint coatings on metal and other substrates. It has been used as a reference for procurement specifications, technical passports and conformity assessments in industries where long-term corrosion protection and surface appearance are important.

Related standards

GOST 9.032-74 is part of the "Unified system of corrosion and ageing protection" series. Closely related documents include GOST 9.104-79 (conditions/groups of operation for coatings), GOST 9.402 (surface preparation before painting) and multiple other GOSTs covering inorganic coatings, test methods and selection procedures. Portions of the unified system have been revised or replaced over time; later or replacement documents (including more recent GOSTs) should be checked for current normative requirements.

FAQ

Q: What is this standard?

A: GOST 9.032-74 is an interstate (originally USSR) standard that established a unified classification, technical requirements and designation rules for lacquer and paint coatings within the unified system for corrosion and ageing protection.

Q: What does it cover?

A: It covers grouping of coatings by intended purpose and exposure conditions, defect tolerance and quality requirements for coating classes (gloss, texture, inclusions, runs, waviness, etc.), rules for marking/designation, and includes appendices on surface preparation, roughness limits, gloss measurement and profilometric texture assessment.

Q: Who typically uses it?

A: Coating manufacturers, materials and corrosion engineers, product specifiers, quality/inspection staff, and maintenance/asset-management organizations that require standardized coating classification and acceptance criteria.

Q: Is it current or superseded?

A: GOST 9.032-74 was officially in force for many years but was withdrawn (document lost force) on 01 February 2025 following the issuance of a Rosstandart order; it has been replaced by newer normative documents (for example GOST 35094-2024 is cited as a replacement). Users should adopt the replacement documents for current regulatory or contractual requirements.

Q: Is it part of a series?

A: Yes — it belongs to the "Unified system of corrosion and ageing protection" family of GOSTs; many companion standards cover operational condition groups, coating selection, inorganic coatings, surface preparation and test methods (examples include GOST 9.104‑79 and GOST 9.402 series).

Q: What are the key keywords?

A: Paint/lacquer coatings, corrosion protection, coating groups, technical requirements, designation, surface preparation, gloss classification, coating defects.
