31、 1 to 6;d) particle size ranges in accordance with the classes given in Table 7;e) necessary requirements for analysis reports packing, etc., as appropriate.5 Requirements5.1 Constitution of consignmentA consignment of a ferromanganese may consist of one or more lots or parts of a lot, which are def
32、ined in ISO 8954-1. In one consignment, one of the following types of lots may be used:a) tapped lot;b) graded lot; ISO 2017 All rights reserved 1BS ISO 5446:2017ISO 5446:2017(E)c) blended lot.5.2 Chemical composition5.2.1 The chemical composition of ferromanganese shall be as specified in Tables 1
33、to 6. The limits stated correspond to particle size ranges in Tables 1 to 6 in accordance with Table 7.5.2.2 Special requirements, such as special ranges for the specified elements, or other requirements for unspecified elements, should be agreed upon between the purchaser and the supplier.5.2.3 The
34、 content of manganese, which is given in Tables 1 to 6, corresponds to the precision of sampling and analysis for ferromanganese (see Clause 6).For other elements, the number of significant digits is set, taking into account the existing methods of analysis and may be agreed upon between the supplie
35、r and the purchaser.5.3 Particle size ranges5.3.1 Ferromanganese is supplied in lumps or as crushed and screened particles. The particle size ranges and tolerances shall be in accordance with Table 7. The undersize values shall be valid at the point of delivery to the purchaser.The particle sizes sp
36、ecified refer to screening on a steel sieve with square openings; see ISO 565.5.3.2 If the purchaser requires particle size ranges and/or tolerances other than those given in Table 7, those shall be agreed upon between the supplier and the purchaser.5.4 Extraneous contaminationThe material shall be
37、as free as possible from extraneous contamination.6 Testing6.1 General6.1.1 The supplier shall establish and supply with the ferromanganese an analysis certificate for the manganese content and, if agreed with the purchaser, for the contents of the other elements either specified in Tables 1 to 6 or
38、 additionally agreed.
