ISO 4938:2016 specifies a method for the determination of nickel in steel and iron by gravimetry or titrimetry. The method is applicable to nickel contents from 1 % to 30 % (mass fraction).
Abstract
Overview
EN ISO 4938:2016 - "Steel and iron - Determination of nickel content - Gravimetric or titrimetric method" is a CEN-adopted ISO standard that specifies validated laboratory procedures for measuring . The standard covers both and routes and applies to nickel mass fractions from . It supersedes EN 24938:1990 and is intended for routine chemical analysis in metallurgical and quality‑control laboratories.
