What is this standard about?
This document specifies requirements for 12 grades of chilled-iron grit abrasives, as supplied for blastcleaning processes. It specifies ranges of particle sizes, together with corresponding grade designations. Values are specified for hardness, density, defect/structural requirements 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.
Test methods for metallic blast-cleaning abrasives are given in the various parts of ISO 11125. Chilled-iron grit 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.
