The work of preparing International Standards is normally carried out through isO technical committees.Eachmemberbodyinterestedinasubjectforwhichatechnicalcommitteehasbeenestablishedhas liaisonwithIsO,alsotakepartinthework.lsOcollaboratescloselywiththeInternationalElectrotechnica Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 3 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 11126-9 was prepared by Technical Committee ISO/TC 35, Paints and varnishes Subcommittee sc 12, Preparation of steel substrates before application of paints and related products. Iso 11126 consists of the following parts, under the general title Preparation of steel substrates before application of paints and related products Specifications for non-metallic blast-cleaning abrasives: Part 1: General introduction and classification Part 3: Copper refinery slag 一 Part 4: Coal furnace slag Part 5: Nickel refinery slag Part 6: Iron furnace slag Part 7: Fused aluminium oxide Part 8: Olivine sand Part 9: Staurolite Part 10: Almandite garnet At the time of publication of this part of isO 11126, part 10 was in the course of preparation. Part 2 has been deleted. @ISO1999 All rights reserved.

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. It is important to ensure that adequate instructions are given and that all required precautions are exercised. 1 Scope specifies ranges of particle sizes and values for apparent density, Mohs hardness, moisture content, conductivity of aqueous extract and water-soluble chlorides. The requirements specified in this part of ISO 11126 apply to abrasives supplied in the "new" condition only. They do not apply to abrasives either during or after use. Test methods for non-metallic blast-cleaning abrasives are given in the various parts of Iso 11127. NOTE 1 Information on commonly referenced national standards for non-metallic abrasives is given in annex A. NOTE 2 Although this part of IsO 11126 has been developed specifically to meet requirements for preparation of steelwork, the properties specified will generally be appropriate for ewhenpreparingothermaterialsurfaces,
