ASTM E1835火焰原子吸收光譜法分析鎳合金標(biāo)準(zhǔn)試驗(yàn)方法
ASTM E1835 Standard Test Method for Analysis of Nickel Alloys by Flame Atomic Absorption Spectrometry
ASTM E1835火焰原子吸收光譜法分析鎳合金標(biāo)準(zhǔn)試驗(yàn)方法
This test method is used for the analysis of nickel alloy samples by FAAS 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) , —International interlaboratory studies 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 E 1601. 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 E 1601.
In this test method, some matrix modifiers are specified. However, other additives have come into common use 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.
1. Scope
1.1 This test method covers analysis of nickel alloys by flame atomic absorption spectrometric analysis (FAAS) for the following elements:
Element    Concentration Range, %
   
Aluminum    0.2 to 4.0
Chromium    0.01 to 4.0
Cobalt    0.01 to 4.0
Copper    0.01 to 4.0
Iron    0.1 to 4.0
Manganese    0.1 to 4.0
Silicon    0.2 to 1.0
Vanadium    0.05 to 1.0
1.2 The concentration range of these elements can be expanded by the use of appropriate standards.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 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.
