GOST 9.105-80 PDF

Full title and description

Unified system of corrosion and ageing protection — Paint coatings. Classification and basic parameters of painting methods (ГОСТ 9.105-80). This interstate standard establishes a classification of painting (coating) methods and defines the principal process parameters and control/measurement requirements used when forming paint and powder coatings.

Abstract

GOST 9.105-80 groups methods of applying paint and powder coatings (spraying, immersion, electrostatic, rolling, brushing, etc.), defines the main measurable parameters (working viscosity, layer thickness, working pressures and voltages, temperatures, times and speeds, distances, material feed rates and others) and provides normative appendices with recommended selection tables, numerical parameter limits, defect criteria and references to measuring instruments. The standard is part of the unified system of corrosion and ageing protection (ЕСЗКС).

Scope

Specifies a classification of methods for applying lacquer and paint materials (liquid dispersed systems, powder systems, volume/coating-in-the-mass processes, layer application methods such as rolling and brushing) and sets the principal parameters to be controlled for each method. The standard is intended to be used where coating method selection, parameter specification and quality control of paint/coating application are required (manufacture, repair, surface finishing and quality laboratories). It includes normative appendices with recommended choice tables, numeric parameter ranges, defect limits and the types of measuring instruments for each parameter.

Key topics and requirements

• Classification of painting methods into groups (I–V) depending on material state and delivery method (e.g., pneumatic spray, airless spray, electrostatic, immersion, powder spray onto heated parts, brushing/rolling, pouring).
• Definition of principal controllable parameters (working viscosity, coating thickness in µm, material and air pressures, voltage for electrostatic methods, application distance, temperatures, drying/curing/evaporation times, feed rates, immersion/withdrawal speeds, centrifuging/centrifugal parameters, etc.).
• Appendices providing: recommended method-selection tables (by material type, coating class, part size/complexity and production type), numeric boundary values for parameters and defect criteria, and lists of instruments/methods for measuring each parameter.
• Normative references to related corrosion-protection and coating standards within the unified protection system (for coating classes, surface preparation, test methods and terminology).

Typical use and users

Used by paint and coating technologists, surface-treatment and finishing shops, production engineers, quality-control and testing laboratories, procurement/specification writers, and standardization bodies when specifying coating application methods and control parameters for industrial, automotive, machinery and metalwork products. The standard is referenced in industrial product descriptions and technical specifications for protective and decorative coatings.

Related standards

Commonly paired with other standards from the Unified System of Corrosion and Ageing Protection, for example: GOST 9.032-74 (paint coatings — groups, technical requirements and designations), GOST 9.104-79 (service-condition groups for coatings), GOST 9.402 (surface preparation before painting) and a number of procedural and test-method GOSTs within the 9.xxx series. These documents define coating classes, surface prep, test methods and specific measurement procedures that complement 9.105-80.
