26、sed 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 substances. These regulations are therefore to be observed. It is important to ensure that adequa

27、te instructions are given and that all required precautions are exercised. 1 Scope This part of ISO11124 specifies requirements for 12 grades of chilled-iron grit abrasives, as supplied for blast-cleaning processes. It specifies ranges of particle sizes, together with corresponding grade designation

28、s. Values are specified for hardness, density, defect/structural requirements and chemical composition. The requirements specified in this part of ISO11124 apply to abrasives supplied in the “new” condition only. They do not apply to abrasives either during or after use. Test methods for metallic bl

29、ast-cleaning abrasives are given in the various parts of ISO11125. Chilled-iron grit abrasives are used in both static and site blasting equipment. They are most often selected where a facility exists for recovery and re-use of the abrasive. NOTE 1Information on commonly referenced national standard

30、s for metallic abrasives and their approximate relationship with ISO11124 is given inAnnex A andAnnex B. NOTE 2Although this part of ISO11124 has been developed specifically to meet requirements for preparation of steelwork, the properties specified will generally be appropriate for use when prepari

31、ng other material surfaces, 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 foll

32、owing standards contain provisions which, through reference in this text, constitute provisions of this part of ISO11124. At the time of publication, the editions indicated were valid.
