Foreword
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. Esch 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.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 11124-2 was prepared by Technical Committee
lSO/TC 35, Paints and varnishes, Subcommittee SC 12, Preparation of
s teel Substrates be fore applica tion o f paints and related products.
ISO 11124 consists of the following Parts, under the general title Prepa-
ra tion o f steel substra tes be fore application o f paints and related
products - Specifica tions for metallic blast-cleaning abrasives:
- Part 1: General introduction and classifica tion
- Part 2: Chilled-iron grit
- Part 3: High-carbon cast-steel shot and grit
- Part 4: Low-carbon cast-steel shot
- Part 5: Cut steel wire
At the time of publication of this part of ISO 11124, part 5 was in course
of preparation.

WARNING - Equipment, materials and abrasives used for surface preparation tan be hazardous
if used carelessly. Many national regulations exist for those materials and abrasives that are
considered to be hazardous during or after use (waste management), such as free silica or
carcinogenic or toxic substances. These regulations are therefore to be observed. lt is important
to ensure that adequate instructions are given and that all required precautions are exercised.
