GOST 9.104-79
Name in Russian:
ГОСТ 9.104-79
Unified system of corrosion and ageing protection. Coatings of lacquers and paints. Croups of operation conditions
Full title and description
GOST 9.104-79 — Единая система защиты от коррозии и старения. Покрытия лакокрасочные. Группы условий эксплуатации. Standard establishing groups of service (operating) conditions for paint and varnish coatings within the Unified System of Protection against Corrosion and Ageing (ЕСЗКС).
Abstract
This standard defines classification groups of environmental and placement conditions that affect lacquer and paint coatings, linking macroclimatic regions and categories of equipment placement (indoor, outdoor, aggressive atmospheres, etc.) to groups of operating conditions. It was intended to be used when selecting protective paint systems, specifying test exposures and acceptance criteria in design and technical documentation.
General information
- Status: Superseded / replaced (withdrawn from active use).
- Publication date: Approved 28 September 1979; put into effect for newly developed products 1 July 1980 (and for items in production 1 July 1983).
- Publisher: State Committee for Standards of the USSR; originally published through the standard publishing body (Standart publishing).
- ICS / categories: ICS 25.220.60 (Organic coatings) — Russian classifiers also show 87.020; part of the ЕСЗКС (Unified system of corrosion and ageing protection) family.
- Edition / version: Original designation GOST 9.104-79 (with Amendment No.1, March 1983). Replaced by GOST 9.104-2018 (effective 1 July 2019).
- Number of pages: Short original leaflet — typically listed as approximately 2 pages (concise grouping table and explanatory notes).
Scope
Applies to lacquer and paint coatings of products and components; establishes groups of operating conditions for coatings with reference to macroclimatic regions and placement categories per GOST 15150. It provides a uniform basis for selecting coating systems, specifying environmental severity for tests, and harmonizing design/technical documentation within the USSR/Russian practice for corrosion protection.
Key topics and requirements
- Definition of groups of operating conditions for paint coatings (classification by climatic macro-region and placement category).
- Mapping of placement categories (indoor, outdoor, sheltered, aggressive atmospheres) to coating-condition groups.
- Reference linkage to GOST 15150 (categories of placement and macroclimatic regions) and other ЕСЗКС standards for tests and selection.
- Guidance used to determine required durability/ protective properties and to select test regimes and acceptance criteria.
- Integration into the broader Unified System of Corrosion and Ageing Protection (ЕСЗКС) for metals and non‑metals.
Typical use and users
Used by paint and coating manufacturers, corrosion engineers, design offices, specification writers, quality and testing laboratories, and regulatory bodies involved in protective coating selection and documentation for machinery, equipment and structures exposed to varying climatic and environmental conditions.
Related standards
Belongs to the ЕСЗКС suite and is closely related to: GOST 15150 (categories of placement and macroclimatic regions), GOST 9.032, GOST 9.072 (terminology), other GOSTs on coatings and corrosion testing. GOST 9.104-79 replaced GOST 9.009-73 and itself was superseded by GOST 9.104-2018 (effective 1 July 2019). It is also conceptually aligned with international standards on atmospheric corrosion and protective coatings such as ISO/EN corrosion/coating standards (for example ISO 12944 series / EN 927 family in scope).

FAQ
Q: What is this standard?
A: GOST 9.104-79 is a USSR-era standard that defines groups of operating (service) conditions for lacquer and paint coatings as part of the Unified System of Protection against Corrosion and Ageing (ЕСЗКС).
Q: What does it cover?
A: It covers classification of environments and placement categories affecting paint coatings (macroclimatic regions, indoor/outdoor placement, atmosphere aggressiveness) and provides the grouping used when specifying protective coating systems and test conditions.
Q: Who typically uses it?
A: Coatings manufacturers, designers and engineers specifying protective systems, test laboratories, quality assurance personnel, and standards/regulatory bodies working with protective paint coatings in industrial and construction applications.
Q: Is it current or superseded?
A: Superseded. GOST 9.104-79 was superseded by a revised standard GOST 9.104-2018, which became effective on 1 July 2019. The 1979 edition is therefore withdrawn from active status and retained only for historical/reference purposes.
Q: Is it part of a series?
A: Yes. It is part of the ЕСЗКС (Unified System of Protection against Corrosion and Ageing) family of standards governing coatings, corrosion tests, terminology and selection procedures; it references and is used alongside related GOSTs such as GOST 15150, GOST 9.032, GOST 9.072 and others in the corrosion/coatings series.
Q: What are the key keywords?
A: Paint coatings, lacquer, service conditions groups, corrosion protection, ЕСЗКС, GOST 15150, atmospheric aggressiveness, coating selection.
