Ferronickel — Determination of carbon, sulphur, silicon, phosphorus, nickel, cobalt, chromium, and copper contents by Spark Emission Spectrometry ISO/CD 4653

Scope

This document specifies a spark atomic emission spectrometry method for the determination of carbon, sulfur, silicon, phosphorus, nickel, cobalt, chromium, copper contents in ferronickel. This method is applicable to the concentration ranges (mass fraction) in ferronickel: carbon 0.02 to 2.5, sulfur 0.002 to 0.28, silicon 0.10 to 4, phosphorus 0.005 to 0.040, nickel 14.0 to 42.0, cobalt 0.20 to 2.0, chromium 0.10 to 2.0, copper to 0.25.
