Standard Test Method for Determination of Phosphorus in Nickel, Ferronickel, and Nickel Alloys by Phosphovanadomolybdate Spectrophotometry


ASTM E1917-2013 发布历史

5.1x00a0;This test method is used for the determination of phosphorus in nickel, ferronickel, and nickel alloy samples by molecular 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 E882.

1.1x00a0;This test method covers the determination of phosphorus in nickel, ferronickel, and nickel alloys in the range 0.00078201;% to 0.058201;%.

1.2x00a0;Arsenic, chromium, hafnium, niobium, silicon, tantalum, titanium, and tungsten interfere, but the interference can be avoided by complexation or volatilization (for chromium). The lowest phosphorus content (0.00078201;%) can be reached only in samples with low contents of interfering elements.

1.3x00a0;The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4x00a0;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 E50. Refer to specific warning notes given throughout this test method.
