CONTAINED IN VOL. 06.03, 2017 Specifies a method for the quantitative determination of ferrous oxide (FeO) by oxidation of ferrous iron (Fe[++]) in an acid solution to the ferric state (Fe[+++]) and titration with potassium dichromate using diphenylamine as the indicator.

1.1This test method covers the quantitative determination of ferrous oxide (FeO) by oxidation of ferrous iron (Fe++) in an acid solution to the ferric state (Fe+++) and titration with potassium dichromate using diphenylamine as the indicator.

1.2This test method is applicable to synthetic black iron oxide, natural black iron oxide, magnetite or brown iron oxide where part of the iron content is present in the ferrous state (Note 1). It is applicable to iron oxides where the ferrous iron content ranges from 50 to 0.20 %.

Note 1:Natural iron oxides and magnetite may contain traces of metallic iron that will be combined with and analyzed as FeO.

1.3This standard does not purport to address the safety concerns if any, problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
