ISO 17058 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 1, Methods of determinationofchemicalcomposition. iv BSIS017058:2004 Steel and iron Determination of arsenic content - Spectrophotometric method Scope This International Standard 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). 2 Normative ref
