17、ed by CEN on1992-05-08. National standards identical to this European Standard shall be published at the latest by1992-11-30 and conflicting national standards shall be withdrawn at the latest1992-11-30. According to the CEN/CENELEC Internal Regulations, the following countries are bound to implemen

18、t this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Endorsement notice The text of the International Standard ISO6501:1988 was approved by CEN as

20、 technical delivery requirements for the various forms of ferronickel (ingots, pieces and shot) usually supplied for steel making and foundry use. 2 Definition ferronickel a master alloy of iron and nickel having a nickel content equal to or greater than15%(m/m), and less than80%(m/m), obtained from

21、 oxide ores or other nickel-bearing materials 3 Information for ordering Orders for ferronickel shall include the following information: a) quantity; b) chemical composition, according to the designations in the table; c) form of delivery, according to4.2; d) requirements for analysis reports, packi

22、ng, etc., as appropriate. 4 Requirements 4.1 Chemical composition 4.1.1 The chemical compositions of the various types of ferronickel are specified in Table 1. 4.1.2 In Table 1, only the main constituent elements and usual impurities are given. If the purchaser requires closer ranges for the main el

23、ement contents and/or different limits for specified elements, and/or limits for non-specified elements, and/or if the contents of elements such as arsenic, bismuth, lead, antimony and tin each exceed0,010%(m/m), this shall be indicated and agreed upon between supplier and purchaser. 4.1.3 The chemi

24、cal compositions given in Table 1 are subject to the precision of the methods of sampling and analysis for ferronickel. 4.2 Form of delivery and formation of lots Ferronickel may be delivered as agreed between the supplier and the purchaser in various forms, e.g:ingots, pieces or shot. The delivered

25、 lots, except by special agreement, shall have a minimum tonnage of5t. 4.2.1 Ferronickel in ingots Ingots may be supplied notched or unnotched. Their maximum mass is100kg; their thickness may be within a range of30to150mm and their length shall not exceed1100mm. Lots may be formed in two different w

26、ays: from material stocked individually from each tapping operation; by blending several heats; in this case, except by special agreement, heats shall be selected in a nickel content range from K to (K +1)%, K being a whole number. 4.2.2 Ferronickel in pieces Pieces are either cast or cut from ingot

27、s. A lot is formed from only one of these two categories of pieces. The maximum dimension is between25 and100mm. Within a lot, the sizes of pieces shall be uniform. Lots may be formed in two different ways: from material stocked individually from each tapping operation; by blending several heats; in

28、 this case, except by special agreement, heats shall be selected in a nickel content range from K to (K +1)%, K being a whole number. 4.2.3 Ferronickel in the form of shot The size of the shot obtained by shotting of liquid material is within a range of2 to50mm. If so agreed between supplier and pur

29、chaser, the ferronickel shot may 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 b

30、lended material may be selected with values of n up to5; by reclaiming from unblended storage; in this case n shall not exceed1. Deliveries may be made in drums, generally of250kg capacity, but capacities as small as50kg are acceptable. 4.3 Contamination The material shall be as free as possible fro

31、m surface contaminants such as slag, sand, etc. 5 Control Sampling and analysis procedures shall preferably be carried out in accordance with relevant International Standards. Other procedures giving the same accuracy may be agreed upon between supplier and purchaser, and arbitrator in the case of a

32、n arbitration procedure.EN26501:1992 4 BSI 12-1999 5.1 Sampling for analysis 5.1.1 During sampling procedures, representatives of both parties may be present, wherever sampling is carried out. 5.1.2 In case of dispute, one of the procedures described in5.3 may be adopted. 5.2 Analysis 5.2.1 Ferronic

33、kel furnished with analysis certificate The certificate, established by the supplier, gives the nickel content and, if agreed, the content of other elements, either specified in the table or additionally agreed. In case of dispute, the two parties may use the procedures described in5.3 either for an

34、alysis only or for sampling and analysis. 5.2.2 Ferronickel settled with exchange analysis When an exchange of analysis is decided on by the two parties, the values resulting from analysis of the samples obtained under5.1.1 for nickel content, and possibly for the content of other elements, shall be

35、 exchanged. If the differences between the results of the analyses of the two parties do not exceed the agreed splitting limits, the mean value shall be accepted. If the differences exceed these splitting limits, the two parties may use the procedures described in5.3 either for analysis only or for

36、sampling and analysis. 5.3 Procedures in case of dispute The two cases below are applicable for both sampling and analytical problems and may be used either independently or successively. In both cases, the acceptable analytical result shall be within a range with the following limits: the lower con

37、tested value minus splitting limit (in accordance with5.2.2); the higher contested value plus the splitting limit. 5.3.1 Contradictory procedure The procedure is carried out at a place chosen by agreement between the two parties. The operations are performed by one of the two parties in the presence

38、 of the other or of an agreed representative. If analysis is carried out and if the value obtained is within the range defined at the beginning of5.3, it is adopted as the final result. If the value found is outside this range, a new check shall be decided upon, in conformity either with5.3.1 by org

39、anizing another contradictory procedure, or with5.3.2. 5.3.2 Arbitration procedure An arbitrator is chosen by agreement between the two parties. The sample obtained by an arbitration sampling is final. If the arbitrator has the sole responsibility for testing a sample, his result is final. If a samp

40、le is analysed by the two parties and then by the arbitrator, and if the arbitration result is within the range defined at the beginning of5.3, it forms the basis for the final settlement. If the value found is outside this range, a new check shall be decided upon, in conformity either with5.3.1 or

41、with5.3.2 by selecting another arbitrator. 6 Dispatch and storage Ferronickel shall be transported and stored according to current international regulations or according to agreement between supplier and purchaser.
