25、9 3 WARNING Equipment, materials and abrasives used for surface preparation can be hazardous if used carelessly. 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
26、substances. These regulations are therefore to be observed. It is important to ensure that adequate instructions are given and that all required precautions are exercised. 1 Scope This part of ISO11126 specifies requirements for iron furnace slag abrasives, as supplied for blast-cleaning processes.
27、It specifies ranges of particle sizes and values for apparent density, Mohs hardness, moisture content, conductivity of aqueous extract and water-soluble chlorides. The requirements specified in this part of ISO11126 apply to abrasives supplied in the “new” condition only. They do not apply to abras
28、ives either during or after use. Test methods for non-metallic blast-cleaning abrasives are given in the various parts of ISO11127. NOTE 1Information on commonly referenced national standards for non-metallic abrasives is given inAnnex A. NOTE 2Although this part of ISO11126 has been developed speci
29、fically to meet requirements for preparation of steelwork, the properties specified will generally be appropriate for use when preparing other material surfaces, or components, using blast-cleaning techniques. These techniques are described in ISO8504-2:1992, Preparation of steel substrates before a
30、pplication of paints and related products Surface preparation methods Part 2: Abrasive blast-cleaning. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO11126. At the time of publication, the editions ind
31、icated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO11126 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

37、llowing definition applies. 3.1 iron furnace slag a synthetic mineral blast-cleaning abrasive manufactured, by granulation in water, drying and sieving, with or without mechanical crushing processes, from slag originating from iron smelting. It is basically calcium silicate slag NOTE 3Slags manufact
38、ured by air cooling instead of granulation in water are generally of a different mineral structure and are therefore not covered by this part of ISO11126. 4 Designation of abrasives Iron furnace slag abrasives shall be identified by “Abrasive ISO11126” and the abbreviation N/FE indicating non-metall
39、ic, iron furnace slag abrasive. This shall be followed, without spaces, by an oblique stroke and then by the symbolG 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, requi
40、red (seeTable 1).ISO11126-6:1993(E) 4 BSI04-1999 EXAMPLE 1 Abrasive ISO11126 N/FE/G 0,2-1 denotes an abrasive of the non-metallic iron furnace slag type, complying with the requirements of this part of ISO11126, of initial particle shape grit and particle size range0,2mm to 1mm. It is essential that
41、 this full product designation is quoted on all orders. 5 Sampling Sampling procedures shall be as specified in ISO11127-1. 6 Requirements 6.1 General requirements Iron furnace slag abrasives shall be vitreous amorphous materials that absorb no water but may be wetted on the surface only. Silica in
42、iron furnace 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 constituents and adhesion-impairing contaminant
43、s. NOTE 4Iron furnace 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 Particular requirements Particular requiremen
44、ts for iron furnace slag abrasives shall be as specified inTable 2. 7 Identification and marking All supplies shall be clearly marked or identified using the appropriate designation as specified inclause4, either directly or by the accompanying delivery note. 8 Information to be supplied by the manu
45、facturer or supplier The manufacturer or supplier shall supply, if requested, a test report detailing results for any relevant property as determined by the appropriate method specified inTable 2.
