27、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 instructions
28、are given and that all required precautions are exercised. 1 Scope This part of ISO 11126 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, condu
29、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
30、ious parts of ISO 11127. NOTE 1Information on commonly 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 app
31、ropriate for use when preparing other material surfaces, or components, using blast-cleaning techniques. These techniques are described in ISO 8504-2:1992, Preparation of steel substrates before application of paints and related products Surface preparation methods Part 2: Abrasive blast-cleaning. 2

At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part
33、of ISO 11126 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

39、actured, by granulation in water, drying and sieving, 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 a
40、nd are therefore not covered by this part of ISO 11126. 4 Designation of abrasives Copper refinery slag abrasives shall be identified by “Abrasive ISO 11126” and the abbreviation N/CU indicating non-metallic, copper refinery slag abrasive. This shall be followed, without spaces, by an oblique stroke
41、 and then by the symbol G to indicate the required particle shape of the abrasive, when purchased, as grit. The designation shall be completed by numbers denoting the particle size range, in millimetres, required (see Table 1). Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 19 09:01:17 GMT+00:0

43、o 1 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 Copper refinery slag abrasives shall be vitreous amorphous materials that absorb no water but may be wetted
44、 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 crystobalite) shall not exceed 1 % (m/m), as determined by X-ray diffraction. The material shall be free from corrosive constituent
45、s and adhesion-impairing contaminants. NOTE 4Copper refinery slag abrasives as supplied have a predominantly angular shape. More spherical particle shapes are not excluded as their effect on the surface profile obtained corresponds generally to that produced by angular abrasive particles. 6.2 Partic
46、ular requirements Particular requirements for copper refinery slag abrasives shall be as specified in Table 2. 7 Identification and marking All supplies shall be clearly marked or identified using the appropriate designation as specified in clause 4, either directly or by the accompanying delivery n
