25、 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 substances.

26、 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 olivine sand abrasives, as supplied for blast-cleaning processes. It specifies ran

27、ges 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 abrasives either duri

28、ng 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 in Annex A. NOTE 2Although this part of ISO11126 has been developed specifically to meet

29、 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 application of p
