c) form of delivery, according to 5.2;
d) delivery requirements;
e) size distribution;
f) requirements for the analysis report, packing, etc., as appropriate;
g) transportation and storage requirements.
5 Requirements
5.1 Chemical composition
5.1.1 The chemical compositions of the various types of ferronickel are specified in Tables 1 and 2.
5.1.2 In Table 1, only the nickel content is given.
5.1.3 In Table 2, the main constituent elements and usual impurities are given. Other elements may be decided between the parties.
If the purchaser requires closer ranges for the main element 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 exceed mass fraction of 0,010 %, this shall be indicated and agreed upon between the supplier and the purchaser.
5.1.4 The designation of ferronickel product is given with the combination of the elements of
Tables 1 and 2.
EXAMPLE FE Ni 30 HC MP MS HSi, where L = low, M = medium and H = high.
Other examples of a combination of Tables 1 and 2 are given in Annex A.
5.1.5 The chemical compositions given in Tables 1 and 2 are subject to the precision of the methods of sampling and analysis for ferronickel.
5.2 Form of delivery and formation of lots
5.2.1 General
Ferronickel may be delivered as agreed between the supplier and the purchaser in various forms,
e.g. ingots, pieces or shot. The delivered lots, except by special agreement, shall have a minimum
tonnage of 5 t.
5.2.2 Ferronickel in ingots
Ingots may be supplied notched or unnotched. Their maximum mass is 100 kg. Their thickness may be within a range of 30 to 150 mm. Their length shall not exceed 1 100 mm.
Lots may be formed in two different ways:
— 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.
5.2.3 Ferronickel in pieces
Pieces are either cast or cut from ingots. A lot is formed from only one of these two categories of pieces.
The maximum dimension is between 25 and 100 mm. 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 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.BS EN ISO 6501 pdf download.
