一IEC Electropedia: available at http://www.electropedia.org/The size of the shot obtained by shotting of liquid material should be within a range of 2 mm to 50 mm.  The ferronickel shot shall be delivered after drying.Lots generally delivered in bulk may be formed in three different ways:-from material stocked individually from each tapping operation;by reclaiming from blended storage; in this case, the K to (K + n) % range of the nickel content of the blended material may be selected with values ofn up to 5; – -，by reclaiming from unblended storage; in this case, n shall not exceed 1.The material shall be as free as possible from surface contaminants such as slag, sand, etc.  Sampling and analysis procedures shall be carried out in accordance with relevant International Standards, in particular ISO 8049 for the sampling of ferronickel shot, ISO 8050 for the sampling of ferronickel ingot or pieces, ISO 14284 for the sampling and preparation of samples for analysis of steel and iron applicable for ferronickel in molten stage, and ISO 6352 for the determination of nickel content. Other procedures giving the same accuracy may be agreed upon between the supplier and the purchaser, and the arbitrator in the case of an arbitration procedure.BS EN ISO 6501 pdf downlaod.
