BS 6200-3.40.1:1997

This standard BS 6200-3.40.1:1997 Sampling and analysis of iron, steel and other ferrous metals. Methods of analysis. Multi-element methods is classified in these ICS categories:

• 77.080.01 Ferrous metals in general

1.1 This part of ISO 13898 specifies a method for determination of nickel, copper and cobalt contents in unalloyed steel and unalloyed iron within the ranges specified in Table 1 by means of inductively coupled plasma atomic emission spectrometric method.

Table 1 — Application ranges of the elements to be determined

Element	Application range % (m/m)
Nickel	0,001 to 0,30
Copper	0,001 to 0,40
Cobalt	0,001 to 0,10

1.2 This part of ISO 13898 specifies the general requirements for analyses by ICP-AES, preparation and dissolution of the test portion and method of calculation and the procedures used for the evaluation of the precision data of the individual methods specified in the subsequent parts.

1.3 The International Standard specifies two alternative methods of evaluating concentrations in test solutions. One is with, the other is without the use of an internal standard.
