ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

The main changes compared to the previous edition are as follows:

Introduction
ISO 11007-1 specifies a method for the evaluation of the corrosion protection properties of lubricating
grease in the presence of non-flowing water; the test bearing is immersed partially in the test fluid.
In some industries (e.g. wet sections of paper mills, roll neck bearings of rolling mills) the bearings are
submitted to flow of water, rolling emulsions, paper treatment liquors, etc. In case of seal damage of the
bearings, the corrosion inhibitors present in the grease may be potentially washed out, hence impairing
the corrosion protection properties.
This document describes a procedure using the flow of test fluid (wash-out) instead of the non-flow
[1]
conditions described in ISO 11007-1 .
1)
This test method is commonly known as Emcor test in the industry.
A rolling bearing grease may be not suitable to lubricate plain bearings or gears.
The precision of the method described in this document has not yet been determined by an
interlaboratory study.
1) Emcor stands for Emulsion corrosion.

corrosion
chemical reaction on metal surfaces, when (rolling bearing) steel is in contact with moisture, e. g. water
or acid, that causes oxidation of surfaces
4 Principle
A test portion of grease is run in a specialized and carefully cleaned test rig under specified conditions,
after introduction of an aqueous test fluid (distilled water, synthetic sea water, sodium chloride
solution, user-specified solutions), for a period of approximately a week with a predetermined sequence
of running and stopping. At the end of the test period, the apparatus is dismantled and the condition of
the outer ring track of the bearing is examined and rated according to the degree of corrosion.
5 Sampling
Unless otherwise specified, sampling shall be conducted in accordance with ISO 23572. The sample
shall be evaluated on a representative portion. Any drum, barrel, tanker compartment or any type of
container delivered to the end user may be sampled and analysed at the discretion of the purchaser.
