The work of preparing Int
22、ernational 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, in liaison w
23、ith 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 Directives, Part 3. Draft International S
24、tandards 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 elements of this part of ISO 11126 may

28、02 All rithgs rreseved 1 Preparation of steel substrates before application of paints and related products Specifications for non-metallic blast-cleaning abrasives Part 10: Almandite garnet WARNING Equipment, materials and abrasives used for surface preparation can be hazardous if used carelessly. M
29、any 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 ensure that adequate instructions
30、 are given and that all required precautions are exercised. 1Scope 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 hardness, moisture content, con- du
31、ctivity 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 var
32、ious parts ISO 11127. NOTE 1Information on commonly referenced national standards for non-metallic abrasives is given in the Bibliography. NOTE 2Although this part of ISO 11126 has been developed specifically to meet requirements for preparation of steelwork, the properties specified will generally
33、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 methods Part 2: Abrasive blast-clean

42、 as a blast-cleaning abrasive NOTE 1Almandite garnet is an iron aluminium silicate with the chemical formula Fe3Al2(SiO4)3. NOTE 2Other forms of garnet, such as andradite garnet which is a calcium iron silicate with the chemical formula Ca3Fe2(SiO4)3, exist, but these garnet abrasives are not covere
43、d by this part of ISO 11126. 4Designation of abrasives Almandite garnet abrasives shall be identified by “Abrasive ISO 11126” and the abbreviation N/GA indicating non- metallic, almandite garnet abrasive. This shall be followed, without spaces, by an oblique stroke and then by the sym- bol G to indi
44、cate the required particle shape of the abrasive, when purchased, as grit. The designation shall be com- pleted by values denoting the particle size range, in millimetres, required (see Table 1). EXAMPLE Abrasive ISO 11126 N/GA/G 0,2-1 denotes an abrasive of the non-metallic almandite garnet type, c
45、omplying with the requirements of this part of ISO 11126, of initial particle shape grit and particle size rangeto. It is essential that this full product designation is quoted on all orders.
