ferronickel:master alloy of iron and nickel having a nickel content equal to or greater than a mass fraction of 15 %and less than a mass fraction of 80 %, obtained from oxide ores or other nickel-bearing materials.number that represents the lowest nickel content that is part of the lot to be delivered.
splitting limit:maximum acceptable difference between analytical results of nickel or other element agreed by twoparties ( buyer and seller)
lot:discrete and defined quantity of ferronickel ingots, pieces or shots answering to the same qualityspecification (chemical composition and physical characteristics). In Table 2, the main constituent elements and usual impurities are given.Other elements may bedecided between the parties.
lf the purchaser requires closer ranges for the main element contents and/or different limits forspecified elements,and/or limits for non-specified elements, and/or if the contents of elements such asarsenic, bismuth, lead, antimony and tin each exceed mass fraction of 0,010 %, this shall be indicatedand agreed upon between the supplier and the purchaser.
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 minimumtonnage of 5 t.lngots may be supplied notched or unnotched.Their maximum mass is 100 kg.Their thickness may bewithin a range of 30 to 150 mm.Their length shall not exceed 1 100 mm.EN ISO 6501 pdf download.
