This document specifies a routine method after fusion under inert gas for the determination of oxygen in steel. The method is applicable to contents of oxygen between 0,001 % (mass fraction) and 0,02 % (mass fraction).
Abstract
Overview
specifies a routine laboratory method for measuring by fusing a test portion in a single‑use graphite crucible under an inert gas (He or Ar) stream and detecting evolved carbon monoxide/carbon dioxide using . The method covers oxygen contents from and uses calibration against steel certified reference materials (CRMs).
