1.1 These test methods cover procedures for the chemical, mass spectrometric, and spectrochemical analysis of nuclear-grade aluminum oxide and aluminum oxide-boron carbide composite pellets to determine compliance with specifications. 1.2 The analytical procedures appear in the following order: Sections Boron by Titrimetry and ICP OES  8 to 17 Separation of Boron for Mass Spectrometry 18 to 23 Isotopic Composition by Mass Spectrometry 24 to 27 Separation of Halides by Pyrohydrolysis 28 to 31 Chloride and Fluoride by Ion-Selective Electrode 32 to 34 Chloride, Bromide, and Iodide by Amperometric Microtitrimetry 35 to 37 Trace Elements by Emission Spectroscopy 38 to 50 Keywords 51 1.3 The values stated in SI units are to be regarded as the 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 precautionary 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.
