GOST 9.080-77 PDF

Full title and description

Unified system of corrosion and ageing protection. Plastic greases. Accelerated method for determination of corrosion effect on metals (Единая система защиты от коррозии и старения. Смазки пластичные. Ускоренный метод определения коррозионного воздействия на металлы). The standard specifies an accelerated laboratory test procedure to assess the corrosive action of plastic (grease) lubricants on metal specimens.

Abstract

This GOST defines a short-duration accelerated test in which metal test plates are fully immersed in the grease under controlled elevated temperature (temperature selection depends on the grease drop point). After a fixed exposure period the plates are cleaned and examined for signs of corrosion or surface change; results are used to judge the grease's corrosive effect on representative metals.

Scope

Applies to plastic (grease) lubricants and establishes an accelerated laboratory method for determining their corrosive action on metals. The procedure is intended for comparative evaluation and quality control of greases with respect to corrosion protection and compatibility with metallic surfaces. The method is not a full-service corrosion life prognosis but an accelerated screening test for formulation and QC purposes.

Key topics and requirements

• Preparation of metal test plates and removal of surface contaminants before immersion.
• Complete immersion of test plates in a measured layer of grease (typical grease layer above plates ≈ 10 mm) and holding at an elevated temperature chosen according to grease drop point.
• Specified exposure durations (example: for soap-based greases with drop point 75–100 °C a test temperature near 70 °C and 5-hour exposure is indicated in procedure examples).
• Post-exposure cleaning (solvent wash) and visual/comparative assessment of corrosion, staining, pitting, or other surface changes.
• Reference to required laboratory glassware, filter paper, solvents and surface-roughness considerations as normative references in the standard.
• Limits of applicability: intended for laboratory comparative testing of greases — results must be interpreted with respect to the test conditions used.

Typical use and users

Used by grease and lubricant manufacturers, quality-control and testing laboratories, petrochemical and metallurgical R&D groups, military and industrial specification bodies, and certification establishments that evaluate grease compatibility with metal components. It is primarily a QC/qualification test rather than a long-term corrosion prediction method.

FAQ

Q: What is this standard?

A: GOST 9.080-77 is a Soviet-era national standard in the "Unified system of corrosion and ageing protection" that defines an accelerated laboratory method to determine the corrosive effect of plastic (grease) lubricants on metals.

Q: What does it cover?

A: It covers preparation of test specimens, immersion of metal plates in grease at specified elevated temperatures (chosen relative to grease drop point), exposure timing, cleaning after exposure and criteria for visual/comparative assessment of corrosive action. The method is a short, accelerated screening test for QC and comparative evaluation.

Q: Who typically uses it?

A: Lubricant and grease manufacturers, industrial testing laboratories, R&D groups in petrochemical and metallurgical sectors, procurement/specification teams and certification bodies performing quality control and formulation assessments.

Q: Is it current or superseded?

A: The standard designation remains GOST 9.080-77 (1977). Records indicate the original limitation on the period of validity was lifted (protocols in the early 1990s), and the standard is listed as active in several national databases; amendments were issued in 1983 and 1987 and later reprints exist. Users should confirm the edition/amendments applicable to their use.

Q: Is it part of a series?

A: Yes — it is part of the Unified system of corrosion and ageing protection (the ESZKS/GOST 9 series) and is linked to other GOSTs on lubricants, test methods and corrosion protection procedures.

Q: What are the key keywords?

A: Plastic greases, lubricants, corrosion testing, accelerated corrosion method, metal compatibility, GOST 9.080-77.
