Standard Test Method for Analysis of Nickel Alloys by Flame Atomic Absorption Spectrometry

Importancia y uso:

5.1 This test method is used for the analysis of nickel alloy samples by FAAS to check for compliance with compositional specifications. It is assumed that all who use the procedure will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that the work will be performed in a properly equipped laboratory and that proper waste disposal procedures will be followed. Appropriate quality control practices must be followed such as those described in Guide E882.

5.2 Interlaboratory Studies (ILS)5^,6—ILS’s were conducted by ISO/TC 155/SC4, Analysis of Nickel Alloys. Results were evaluated in accordance with ISO 5725:1986 and restated to conform to Practice E1601. The method was published as ISO 7530, Parts 1 through 9. The published ISO statistics are summarized separately for each analyte to correspond with Practice E1601.

5.3 In this test method, some matrix modifiers are specified. However, other additives are now commonly used since the original publication of this test method. These may be equally or more effective but have not been tested. It is the responsibility of the user to validate the use of such additives or the use of different dilutions, or both.
