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 11125-5 was prepared by Technical Committee
lSO/TC 35, Paints and varnishes, Subcommittee SC 12, Preparation of
steel substra tes be fore applica tion o f pain ts and related products.
ISO 11125 consists of the following Parts, under the general title Prep-
aration of steel Substrates before application of paints and related
products - Test methods for metallic blast-cleaning abrasives:
- Part 1: Sampling
- Part 2: Determination of particle size distribution
- Part 3: Determination of hardness
- Part 4: Determination of apparent density
- Part 5: Determination of percentage defective particles and of
micros truc ture
- Part 6: Determination of foreign matter
- Part 7: Determination o f moisture
- Part 8: Determination of abrasive mechanical properties
