Scope

1.1 This guide covers information for using Combustion, Inert Gas Fusion and Hot Extraction instruments to determine the mass fraction of the non-metallic elements Carbon, Sulfur, Nitrogen, Oxygen and Hydrogen in metals, ores and related materials. 1.2 This guide does not specify all the operating conditions because of the differences among different manufacturer’s instruments. Laboratories should follow instructions provided by the manufacturer of the instrument. 1.3 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, 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. 1.5 The information in this guide is contained in the sections indicated as follows: Sections Carbon/Sulfur by Combustion/Infrared Detection 14 – 19 Nitrogen/Oxygen by Inert Gas Fusion/Thermal Conductivity and Infrared Detection 20 – 25 Hydrogen by Inert Gas Fusion Instrumental Measurement and Hot Extraction/Various Detection Cell Technology 26 – 31 1.6 This 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.
