ASTM E1917-02
Historical Standard: ASTM E1917-02 Standard Test Method for Determination of Phosphorous in Nickel, Ferronickel, and Nickel Alloys by the Phosphovanadomolybdate Molecular Absorption Spectrometric Method
SUPERSEDED (see Active link, below)
ASTM E1917
1. Scope
1.1 This test method covers the determination of phosphorus in nickel, ferronickel, and nickel alloys in the 0.0007 % through 0.05 % range.
1.2 Arsenic, chromium, hafnium, niobium, silicon, tantalum, titanium, and tungsten interfere, but the interference can be avoided by complexation or volatilization (for Cr). The lowest phosphorus content (0.0007 %) can be reached only in samples with low contents of interfering elements.
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 practice see Practices E 50. Refer to specific warning notes given throughout this test method.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
