Many national regulations exist for those ma
25、terials 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
26、are exercised. 1 Scope This part of ISO11126 specifies requirements for copper refinery slag 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
27、chlorides. The requirements specified in this part of ISO11126 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 ISO11127. NOTE 1Information on c
28、ommonly referenced national standards for non-metallic abrasives is given in Annex A. NOTE 2Although this part of ISO11126 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
29、urfaces, or components, using blast-cleaning techniques. These techniques are described in ISO8504-2:1992, Preparation of steel substrates before application of paints and related products Surface preparation methods Part 2: Abrasive blast-cleaning. 2 Normative references The following standards con

37、, with or without mechanical crushing processes, from slag originating from copper smelting. It is basically iron silicate slag NOTE 3Slags manufactured by air cooling instead of granulation in water are generally of a different mineral structure and are therefore not covered by this part of ISO1112
38、6. 4 Designation of abrasives Copper refinery slag abrasives shall be identified by “Abrasive ISO11126” and the abbreviation N/CU indicating non-metallic, copper refinery slag abrasive. This shall be followed, without spaces, by an oblique stroke and then by the symbol G to indicate the required par
39、ticle shape of the abrasive, when purchased, as grit. The designation shall be completed by numbers denoting the particle size range, in millimetres, required (seeTable 1).ENISO11126-3:1997 4 BSI 04-1999 EXAMPLE 1 Abrasive ISO 11126 N/CU/G 0,5-1 denotes an abrasive of the non-metallic copper refiner
40、y slag type, complying with the requirements of this part of ISO11126, of initial particle shape grit and particle size range0,5mm to1mm. It is essential that this full product designation is quoted on all orders. 5 Sampling Sampling procedures shall be as specified in ISO11127-1. 6 Requirements 6.1
41、 General requirements Copper refinery slag abrasives shall be vitreous amorphous materials that absorb no water but may be wetted on the surface only. Silica in copper refinery slag abrasives shall be present as bonded silicate. The content of free crystalline silica (such as quartz, tridimite or cr
42、ystobalite) shall not exceed1% (m/m), as determined by X-ray diffraction. The material shall be free from corrosive constituents and adhesion-impairing contaminants. NOTE 4Copper refinery slag abrasives as supplied have a predominantly angular shape. More spherical particle shapes are not excluded a
43、s their effect on the surface profile obtained corresponds generally to that produced by angular abrasive particles. 6.2 Particular requirements Particular requirements for copper refinery slag abrasives shall be as specified inTable 2. 7 Identification and marking All supplies shall be clearly mark
44、ed or identified using the appropriate designation as specified in clause4, 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 pro
45、perty as determined by the appropriate method specified in Table 2.
