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. 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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

International Standard ISO 11124-7:2025(en)
Preparation of steel substrates before application of paints
and related products — Specifications for metallic blast-
cleaning abrasives —
Part 7:
High chromium white cast iron grit
1 Scope
This document specifies requirements for high chromium white cast iron grit, as supplied for blast-cleaning
processes. It specifies ranges of particle sizes, together with corresponding grade designations. Values are
specified for hardness, density, defect/structural requirements, metallographic structure and chemical
composition.
The requirements specified in this document apply to abrasives supplied in the new condition only. They do
not apply to abrasives either during or after use.
High chromium white cast iron grits are used in both static and site blasting equipment. They are most often
selected where there is a possibility for the recovery and re-use of the abrasive.
NOTE 1 Although this document has been developed for preparation of steelwork, these materials are
predominantly used for non-ferrous substrates. The properties specified will generally be appropriate for use when
preparing other material surfaces, or components, using blast-cleaning techniques, and can be used for applications
where no subsequent coating is applied.
NOTE 2 Whenever dissimilar metals are used together, galvanic corrosion can occur.
