ENISO111269:2004ENISO111269:2004EN ISO 11126-9:2004 ii BSI 25 April 2005 Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards
19、bodies (ISO member 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 organizat
20、ions, governmental and non-governmental, in 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 th
21、e ISO/IEC 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 prep
22、ared 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 rela
23、ted products Specifications for non-metallic blast-cleaning abrasives: Part 1: General introduction and classification; Part 3: Copper refinery slag; 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: Staur
24、olite; 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.EN ISO 11126-9:2004 BSI 25 April 2005 1 WARNING Equipment, materials and abrasives used for surface preparation can be hazardous if used carelessl
25、y. 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 instructio
26、ns are given and that all required precautions 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
27、 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 pa
28、rts 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 appropri
29、ate for use when preparing other material surfaces, or components, using blast-cleaning techniques. These techniques are described in ISO 8504-2:1992.

37、11126, the following term and definition apply. 3.1 staurolite a material manufactured from the naturally occurring mineral staurolite which is washed, dried, sieved, magnetically separated, and prepared for use as a blast-cleaning abrasive NOTE Staurolite is an iron/aluminium silicate with the appr
38、oximate chemical formula FeAl 5 SiO 12 OH.EN ISO 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 obli
39、que stroke, and then the symbol S to indicate the 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). NOTE Although staurolite is designated as a shot material, the g
40、rit comparator is used when assessing the profile 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 a
41、nd particle size range 0,2 to 0,6 mm. It is essential 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-i
42、mpairing contaminants. Foreign, harmful impurities 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 sha
43、ll be clearly marked or identified using the appropriate 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 f
