Описание (английский):

This document specifies a method for the determination of the rust prevention characteristics of lubricating grease under dynamic wet conditions. This test method is used to assess the ability of a grease to prevent corrosion in rolling bearings operated in presence of water, synthetic sea water or any industrial aqueous pollutant. NOTE For the purposes of this document, the term “% (m/m)” is used to represent the mass fraction.

Overview

ISO 11007-1:2021 - "Petroleum products and lubricants - Determination of rust-prevention characteristics of lubricating greases - Part 1: Dynamic wet conditions" - specifies a standardized laboratory method to evaluate the rust‑prevention (corrosion protection) properties of lubricating greases under dynamic wet conditions. Commonly known in industry as the Emcor test, it assesses a grease’s ability to protect rolling bearings when exposed to water, synthetic sea water or industrial aqueous pollutants.

Key topics and technical requirements

Test principle: A measured quantity of grease is placed in a specially prepared test rig containing double‑row self‑aligning ball bearings. An aqueous test fluid is introduced and the rig is run according to a prescribed sequence of running and stopping (typically over about a week). After the test, the outer ring raceway is inspected and rated for corrosion.

Test fluids permitted: Grade 2 water (ISO 3696), synthetic sea water (see ISO 7120) or a 0.5 mol/L NaCl solution at pH 8.0–8.2. Other user‑specified aqueous pollutants may be used (precision not established).

Apparatus & materials: Clean test rig (Annex A), specified bearings conforming to ISO 15, oven for drying (90 °C ±2 °C), pipettes, solvent rinse (propan‑2‑ol + ammonia), silver nitrate for chloride checks, wash solvents.

Preparation & cleaning: Detailed procedures to remove rust‑preventatives and ensure bearings and plummer blocks are free of contamination; silver nitrate check for residual chlorides after sea‑water tests.

Measurement & reporting: Mass/volume of grease to be placed in bearings, inspection criteria and corrosion rating method, and precision data (repeatability and reproducibility) are included.

Safety note: The standard warns of hazardous materials and operations and emphasizes user responsibility for health/safety measures.

Applications

Quality control and acceptance testing for lubricating greases used in rolling bearings.

Product development and comparative performance testing in lubricant R&D.

Supplier qualification and batch verification for industries where equipment may be exposed to moisture or seawater (marine, offshore, industrial machinery).

Performance classification under ISO 6743‑9 grease designation systems (third symbol relates to water resistance and corrosion protection).
