This International Standard describes a method for the determination of trace elements in green and calcined coke with an ash content of not greater than 1 % (m/m) and with individual concentrations not greater than the following:
Calcium | 0,025 % (m/m) |
Chromium | 0,005 % (m/m) |
Copper | 0,025 % (m/m) |
Iron | 0,030 % (m/m) |
Lead | 0,010 % (m/m) |
Magnesium | 0,010 % (m/m) |
Manganese | 0,001 % (m/m) |
Nickel | 0,050 % (m/m) |
Silicon | 0,100 % (m/m) |
Vanadium | 0,100 % (m/m) |
Zinc | 0,004 % (m/m) |
NOTE A method for the determination of ash of cokes is given in ISO 8005:1984, Carbonaceous materials used in the production of aluminium — Green and calcined coke — Determination of ash. However, it is essential that the ash produced by that method not be used in the procedure of this International Standard because of the risk of contamination by trace elements.
