ISO 17058:2004 specifies a method for the determination of the arsenic content in steel and iron using a spectrophotometric method after distillation. The method is applicable to an arsenic content between 0,000 5 % (mass fraction) and 0,10 % (mass fraction).
Abstract
Overview
ISO 17058:2004 defines a standardized . The method covers measurement after chemical digestion and distillation and is applicable to arsenic mass fractions from . The procedure produces a molybdenum‑blue complex measured at approximately , enabling quantitative arsenic determination for metallurgical quality control and certification.
