This part of ISO 11124 specifies requirements for 12
grades of Iow-carbon cast-steel shot abrasive, as
supplied for blast-cleaning processes. Values are
specified for hardness, density, defect/structural requirements
and Chemical composition.
The requirements specified in this part of ISO 11124
apply to abrasives supplied in the new condition
only. They do not apply to abrasives either during or
after use.
Test methods for metallic blast-cleaning abrasives
are given in the various Parts of ISO 11125.
Low-carbon cast-steel shot abrasives are used in both
static and site blasting equipment. They are most often
selected where a facility exists for recovery and
re-use of the abrasive.
NOTES
1 Information on commonly referenced national Standards
for metallic abrasives and their approximate relationship
with ISO 11124 is given in annexes A and B.
2 Although this part of ISO 11124 has been developed
specifically to meet requirements for preparation of
steelwork, the properties specified will generally be appropriate
for use when preparing other material surfaces, or
components, using blast-cleaning techniques. These techniques
are described in ISO 8504-2:1992, Preparation of
steel Substrates before application of paints and related
products - Surface preparation methods - Part 2: Abrasive
blas t-cleaning.
Dieser Teil der Norm legt Anforderungen für 12 Klassen von kugeligen Strahlmitteln aus Stahlguß mit niedrigem Kohlenstoffgehalt fest. Für Härte, scheinbare Dichte, Defekte, Anforderungen an das Gefüge und die chemische Zusammensetzung sind Grenzwerte festgelegt. Die in diesem Teil der Norm festgelegten Anforderungen gelten nur für im "Neuzustand" gelieferte, unbenutzte Strahlmittel. Sie gelten nicht für Strahlmittel während oder nach der Verwendung.
