This test method is used for the analysis of nickel and nickel-base alloy samples by flame atomic absorption spectrometry to check 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 E 882.
Interlaboratory Studies (ILS)4 -This test method was evaluated by a subcommittee within ISO Technical Committee 155 (ISO/TC 155/SC 4) on analysis of nickel alloys, in accordance with ISO Standard 5725. It was published as ISO Standard 7530, Parts 2 through 9. The ILS test data was not available for recalculation. The published ISO statistics are summarized separately for each analyte.View Less

|Element||Concentration Range, %||Section|
|Aluminum||0.2 to 4.0||12|
|Chromium||0.01 to 4.0||13|
|Cobalt||0.01 to 4.0||14|
|Copper||0.01 to 4.0||15|
|Iron||0.1 to 4.0||16|
|Manganese||0.1 to 4.0||17|
|Silicon||0.2 to 1.0||18|
|Vanadium||0.05 to 1.0||19|
1.2 The concentration range of these elements can be expanded by the use of appropriate standards.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazards associated with the use of this test method see Practices E 50 and the warning statements included in this test method.
