This International Standard specifies an electrothermal atomic absorption spectrometric method for the determination of the silver, arsenic, bismuth, cadmium, lead, antimony, selenium, tin, tellurium and thallium contents of high purity, refined, wrought and cast nickel within the ranges specified in Table 1. This method is applicable to the independent determination of any one or more of the elements listed without including all elements specified in the standard solutions.
Table 1 – Concentration ranges of elements to be determined
| Element | Concentration rangea (µg/g)b |
| Ag | 0,1 to 10 |
| As | 1 to 20 |
| Bi | 0,5 to 15 |
| Cd | 0,1 to 2 |
| Pb | 0,1 to 10 |
| Sb | 1 to 10 |
| Se | 1 to 10 |
| Sn | 1 to 5 |
| Te | 0,2 to 10 |
| Tl | 0,5 to 10 |
a For specific compositions, see ISO 6283.
b 1 µg/g = 1 g/t
