Sampling and analysis of nickel, ferronickel and nickel alloys - Method for the determination of phosphorus in nickel, ferronickel and nickel alloys by phosphovanadomolybdate molecular absorption spectrometry Ingestion-build-134498 lift (elevator) systems1 Scope This International Standard specifies a molecular absorption spectrometric method for the determination of the phosphorus content in nickel, ferronickel and nickel base alloys in the range of 0,000 5 % (m m) to 0,05 % (m m). Arsenic, chromium, hafnium, niobium, silicon, tantalum, titanium and tungsten interfere, but the interferences can be avoided by complexation or volatilisation (for Cr). The lowest phosphorus content [0,000 5 % (m m)] can
