Scope of standard 1.1 These test methods cover procedures for the chemical, mass spectrometric, spectrochemical, nuclear, and radiochemical analysis of nuclear-grade plutonium metal to determine compliance with specifications. 1.2 The analytical procedures appear in the following order: Sections Dissolution Procedure 2 Plutonium by Controlled-Potential Coulometry 3 Plutonium by Amperometric Titration with Iron (II) 2 Plutonium by Ceric Sulfate Titration Test Method 3 Plutonium by Diode Array Spectrophotometry 3 Uranium by Arsenazo I Spectrophotometric Test Method 8 - 10 Thorium by Thorin Spectrophotometric Test Method 11 - 13 Iron by 1,10-Phenanthroline Spectrophotometric Test Method 14 - 16 Iron by 2,2ʹ-Bipyridyl Spectrophotometric Test Method 17 - 23 Impurities by ICP-AES Chloride by the Thiocyanate Spectrophotometric Test Method 24 - 26 Fluoride by Distillation-Spectrophotometric Test Method 27-28 Nitrogen by Distillation-Nessler Reagent Spectrophotometric Test Method 29-30 Carbon by the Direct Combustion-Thermal Conductivity Test Method 31 - 33 Sulfur by Distillation-Spectrophotometric Test Method 34 - 36 Isotopic Composition by Mass Spectrometry 37 and 38 Plutonium-238 Isotopic Abundance by Alpha Spectrometry Americium-241 by Extraction and Gamma Counting 39 - 41 Americium-241 by Gamma Counting 3 Gamma-Emitting Fission Products, Uranium, and Thorium by Gamma-Ray Spectroscopy 42 - 49 Rare Earths by Copper Spark Spectrochemical Test Method 50 - 52 Tungsten, Niobium (Columbium), and Tantalum by Spectro- chemical Test Method 53 - 55 Sample Preparation for Spectrographic Analysis for Trace Impuri- ties 56 - 60 1.3 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. For specific safeguard and safety hazards statements, see Section 6. 1.5 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.
