21、 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
22、 and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commis- sion (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Direct
23、ives, 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. Attention is drawn to the possibility that some of the elem
24、ents of this part of ISO 11126 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 11126-10 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 12, Preparation of steel subst

28、e hazardous if used carelessly. Many national regulations exist for those materials and abrasives that are considered to be haz- ardous 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
29、ensure that adequate instructions are given and that all required precautions are exercised. 1 Scope This part of ISO 11126 specifies requirements for almandite garnet abrasives, as supplied for blast-cleaning pro- cesses. It specifies ranges of particle sizes and values for apparent density, Mohs h
30、ardness, moisture content, con- ductivity 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-clean
31、ing abrasives are given in the various parts ISO 11127. NOTE 1 Information on commonly referenced national standards for non-metallic abrasives is given in the Bibliography. NOTE 2 Although this part of ISO 11126 has been developed specifically to meet requirements for preparation of steelwork, the
32、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 8504-2:2000, Preparation of steel substrates before application of paints and related products Surface preparation
