GOST 9.104-2018 PDF

Full title and description

GOST 9.104-2018 — "Unified system of corrosion and ageing protection. Paint coatings. Groups of operation conditions." The standard defines groups (classes) of service/exposure conditions for paint and coating systems used on metallic and non‑metallic products and links those groups to macro‑climatic regions, placement categories and atmospheric corrosivity classifications.

Abstract

GOST 9.104-2018 establishes a harmonized classification of operating conditions for lacquer and paint coatings, intended to be used when selecting protective coating systems, specifying tests and assessing expected durability under different climatic and atmospheric corrosivity conditions. It updates and replaces the earlier ГОСТ 9.104-79 and aligns with relevant international references (e.g., ISO 8044 and ISO 12944‑2 principles).

Scope

This standard applies to paint and varnish (lacquer) coatings on metallic and non‑metallic articles. It establishes groups of operating conditions for macro‑climatic districts, placement categories per GOST 15150 and categories of atmospheric corrosivity; it is intended for use in specification, selection and testing planning of protective coating systems and for harmonizing durability assessments. Normative references to related GOSTs and international standards are included.

Key topics and requirements

• Classification of groups (categories) of operating/exposure conditions for paint coatings (indoor, sheltered, outdoor, aggressive atmospheres, marine, industrial, etc.).
• Mapping of groups to macro‑climatic regions and placement categories (references to GOST 15150 and atmospheric corrosivity classifications per GOST 9.039).
• Guidance to users/specifiers on how to select coating systems and the environmental conditions that determine accelerated testing needs.
• Normative cross‑references to other corrosion and coating standards and annexes with examples of typical environments and correspondence tables to atmosphere types.

Typical use and users

Used by coating formulators and manufacturers, corrosion and coatings engineers, specification writers, testing laboratories, asset owners and maintenance planners, design offices and regulatory bodies involved in specifying protective systems for equipment, structures and products exposed to climatic and atmospheric influences. It is also used as a reference in procurement and quality documentation for painted items.

Related standards

Commonly referenced standards include GOST 9.039‑74 (atmospheric corrosivity classification), GOST 15150‑69 (climatic versions and placement categories), GOST 16350‑80 and GOST 24482‑80 (macrocimate zoning), ISO 8044:2015 and ISO 12944‑2:2017 (concepts and category mapping), and related paint/coating test and performance standards such as GOST 9.401 series.
