GOST 2917-76 PDF

Full title and description

GOST 2917-76 — Масла и присадки. Метод определения коррозионного воздействия на металлы (Oils and additives. Method of test for corrosion influence on metals). The standard specifies a laboratory test method to evaluate the corrosive effect of lubricating oils, hydraulic oils and oil additives on metal specimens (for example copper strip), by exposure at elevated temperature and subsequent visual assessment.

Abstract

This standard defines the apparatus, sample preparation, test conditions (temperature and exposure time), test specimens and the procedure for assessing corrosion caused by oils and additives on metals. The method’s essence is immersion of a prepared metal plate in the test liquid at controlled elevated temperature for a prescribed time, followed by visual evaluation of surface changes to characterise corrosivity. The standard was developed for quality control and specification testing of lubricants and related products.

• Number of pages: Approximately 5 pages (concise test method).

Scope

GOST 2917-76 applies to lubricating oils, hydraulic oils, finished oils with additives and chemical additive products for which evaluation of corrosive action on metals is required. It specifies a reproducible laboratory procedure to determine whether a tested oil or additive produces corrosion on metal specimens under defined elevated-temperature conditions and exposure times; if no specific temperature/time is given in accompanying product specifications, the standard gives default test conditions (commonly cited practice: 100 °C for 180 minutes). The method is intended for routine quality control, specification verification and comparative testing.

Key topics and requirements

• Definition of apparatus: temperature-controlled oil bath, aluminium block or drying oven able to maintain test temperature within ±1 °C and allow specified immersion depth.
• Preparation and dimensions of metallic test specimens (e.g., copper strip / plate and other specified metals) and their surface preparation prior to exposure.
• Specified test temperatures and exposure durations; guidance when product-specific conditions are absent (common practice used in laboratories).
• Visual assessment criteria for corrosion: appearance changes, discoloration, pitting or other surface damage compared with reference/blank specimens.
• Reporting requirements: test conditions, specimen material, observations and grading of corrosive effect to allow comparative evaluation and quality decisions.

Typical use and users

Laboratories performing quality control of lubricants and hydraulic fluids, additive manufacturers, refinery and petrochemical QC labs, test houses and research organisations use this standard to verify corrosivity properties of oils and additives, to support product specifications, and to examine compatibility with metal components. Industrial contract laboratories and in‑house R&D groups commonly adopt the method for routine and comparative testing.

Related standards

GOST 2917-76 replaces the earlier GOST 2917-45 and is noted to correspond in part to ISO 2160 (copper strip corrosion test) — the standard is therefore closely related to international lubricant corrosion test methods and other national GOST standards for oils and test procedures. Users often consult ISO 2160 and neighbouring GOST test methods when defining complete lubricant test programmes.

FAQ

Q: What is this standard?

A: GOST 2917-76 is a Soviet / interstate standard that specifies a laboratory method to determine the corrosive effect of oils and oil additives on metal specimens by exposure at elevated temperature and visual assessment.

Q: What does it cover?

A: It covers apparatus, specimen preparation, test conditions (temperature/time), exposure procedure and assessment/reporting for evaluating corrosive impact of lubricating and hydraulic oils and additives on metals (notably copper strip testing among the procedures referenced).

Q: Who typically uses it?

A: Quality control and testing laboratories in the oil, lubricant and additive industries, manufacturing quality departments, independent test houses and research organisations use this method for product verification and comparative corrosivity testing.

Q: Is it current or superseded?

A: The standard is listed as in force (действует) in available GOST catalogues and is published with amendments from 1983 and 1988; it replaced GOST 2917-45. For specific regulatory or contractual needs users should confirm the applicable edition or any newer national/international replacements in force at the time of their enquiry.

Q: Is it part of a series?

A: It belongs to the family of standards for oils and petroleum products test methods and is linked to related GOST methods and international standards (for example, ISO 2160 for copper strip corrosion), forming part of standard test suites used in lubricant specification and quality control.

Q: What are the key keywords?
