Many national regulations exist for those materials and abrasives that are considered to

27、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 are exercised. 1 Scope This part of ISO11124

28、specifies requirements for12grades of low-carbon cast-steel shot abrasive, as supplied for blast-cleaning processes. 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

29、 the “new” condition only. They do not apply to abrasives either during or after use. Test methods for metallic blast-cleaning abrasives are given in the various parts of ISO11125. Low-carbon cast-steel shot abrasives are used in both static and site blasting equipment. They are most often selected

30、where a facility exists for recovery and re-use of the abrasive. NOTE 1Information on commonly referenced national standards for metallic abrasives and their approximate relationship with ISO11124 is given inAnnex A and Annex B. NOTE 2Although this part of ISO 11124 has been developed specifically t

31、o 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 applicatio

45、on cast-steel shot abrasives shall be identified by “Abrasive ISO11124” and the abbreviation “M/LCS” indicating metallic, low-carbon cast-steel abrasive. The symbol “S” shall follow to indicate the required particle shape of the shot as purchased. The designation shall be completed by a3-digit numbe

46、r denoting the grade, or nominal particle size, required. EXAMPLE 1 Abrasive ISO 11124 M/LCS/S100 denotes an abrasive of the metallic, low-carbon cast-steel type, complying with the requirements of this part of ISO11124, of particle shape shot and grade100 (i.e.nominal particle size1,00mm). It is es

NOTE 3Grade requirements and codes are specified inTable 1, The grade code is based on a number indicating the approximate middle of the particle size range, or nominal diameter, for each grade, expressed in millimetres 100. NOTE 4A

48、nnex A provides guidance on approximately equivalent grades and codings in other commonly referenced national standards for cast metal abrasives. 5 Sampling Sampling procedures shall be as specified in ISO11125-1. 6 Requirements for low-carbon cast-steel shot abrasives The requirements for low-carbo
