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.

Introduction
This document is a part of the ISO 11125 series that specifies test methods for metallic blast-cleaning
abrasives.
During blast-cleaning, metallic abrasives are subjected to repeated impacts on the substrate to be
prepared. These mechanical impacts result in abrasive material fatigue until particles breakdown.
The service life of the metallic blast-cleaning abrasives is influenced by:
— the type of abrasive, in particular, its size and shape, its resilience, its hardness and its internal
defects;
— the hardness and the surface conditions of the substrate to be prepared;
— the blasting machine and its settings.
The principle of an abrasive service life testing machine is based on a high number of impacts between
a representative sample of the abrasive to be tested and a given target.
Several testing machines exist on the market and depending on their design, the service life obtained
under laboratory conditions may or may not be comparable to field operation.
It is important that the user is aware of the different parameters and the respective adjustability. The
parameters of the testing machines can vary from one machine to another and therefore can result in
different test results.
In general, the effect of wear and consumption are tested. Special arrangements may be required for
specific test procedures. The results can be used for comparison purposes (quality inspection) or for
monitoring (quality control) of the deliveries for uniformity.

Part 9:
Wear testing and performance
1 Scope
This document specifies three procedures to test the service life of a blast-cleaning abrasive under
laboratory conditions.
The performance of an abrasive is also measured by its ability to clean, via transmission of kinetic
energy to the substrate in the blasting process. This document also specifies the procedures that can
be performed in the same testing machines to help evaluate abrasive performance under laboratory
conditions.
This document applies to the testing of virgin metallic blasting media in the delivery state by centrifugal
blasting under laboratory conditions.
