The work of pr
20、eparing 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 and non-governmental, i
21、n liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft Intern
22、ational 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, Pai
23、nts 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-metall

EN ISO 11126-9:2004 BSI 25 April 2005 1 WARNING Equipment, materials and abrasives used for surface preparation can be hazardous if used carelessly. Many national regulations exist for th
26、ose 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 precau
27、tions are exercised. 1 Scope This part of ISO 11126 specifies requirements for staurolite abrasives, as supplied for blast-cleaning processes. It specifies ranges of particle sizes and values for apparent density, Mohs hardness, moisture content, conductivity of aqueous extract and water-soluble chl
28、orides. 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 1Information on co
29、mmonly referenced national standards for non-metallic abrasives is given in Annex A. NOTE 2Although this part of ISO 11126 has been developed specifically to meet requirements for preparation of steelwork, the properties specified will generally be appropriate for use when preparing other material s
30、urfaces, or components, using blast-cleaning techniques. These techniques are described in ISO 8504-2:1992.

39、O 11126-9:2004 2 BSI 25 April 2005 4 Designation of abrasives Staurolite sand abrasives shall be identified by “Abrasive ISO 11126” and the abbreviation N/ST indicating non-metallic staurolite abrasive. This shall be followed, without spaces, by an oblique stroke, and then the symbol S to indicate t
40、he required particle shape of the abrasive, when purchased, as shot. The designation shall be completed by numbers denoting the particle size range, in millimetres, required (see Table 1). NOTEAlthough staurolite is designated as a shot material, the grit comparator is used when assessing the profil
41、e produced. This is due to it having an irregular grain shape. EXAMPLE Abrasive ISO 11126 N/ST/S 0,20,6 denotes an abrasive of the non-metallic staurolite type, complying with the requirements of this part of ISO 11126, of initial particle shape shot and particle size range 0,2 to 0,6 mm. It is esse
42、ntial that this full product designation is quoted on all orders. 5 Sampling Sampling procedures shall be as specified in ISO 11127-1. 6 Requirements 6.1 General requirements Staurolite abrasives shall be free from corrosive constituents and adhesion-impairing contaminants. Foreign, harmful impuriti
43、es shall not be permitted. Silica in staurolite abrasives shall be present as bonded silicate. 6.2 Particular requirements Particular requirements for staurolite abrasives shall be as specified in Table 2. 7 Identification and marking All materials shall be clearly marked or identified using the app
44、ropriate designation as specified in Clause 4, either directly or by the accompanying delivery note. 8 Information to be supplied by the manufacturer or supplier The manufacturer or supplier shall supply, if requested, a test report detailing results for any relevant property as determined by the ap
