Description

This International Standard specifies a flame atomic absorption spectrometric method for the determination of the silver, bismuth, cadmium, cobalt, copper, iron, manganese, lead and zinc contents of 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 the elements specified in the standard solutions.

Table 1 – Concentration ranges of elements to be determined

The lower level for iron can be extended to less than 0,002 5 % (m/m) provided nickel containing less than 0,000 1 % (m/m) iron is used for preparation of standard solutions; see 4.1.

The upper limit for the determination of cobalt and copper can be raised to 2 % (m/m) by a minor modification to the method; see 11.1.

For potential interferences, see clause 10.

For refined, wrought and cast nickel; ranges for elements to be determined are specified.
