1.1These test methods cover procedures for the chemical, mass spectrometric, and spectrochemical analysis of nuclear-grade boron carbide powder and pellets to determine compliance with specifications.
1.2The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3The analytical procedures appear in the following order:
| Sections | |
| Total Carbon by Combustion in an Inductive Furnace and | 8 – 17 |
| Total Boron by Titrimetry and ICP-OES | 18 – 28 |
| Isotopic Composition by Mass Spectrometry | 29 – 33 |
| Pyrohydrolysis | 34 – 41 |
| Chloride by Constant-Current Coulometry | 42 – 50 |
| Chloride and Fluoride by Ion-Selective Electrode | 51 – 59 |
| Water by Constant-Voltage Coulometry and Weight Loss on | 60 – 63 |
| Metallic Impurities by DCArc-OES and wet chemical methods | 64 and 65 |
| Soluble Boron by Titrimetry and ICP-OES | 66 – 80 |
| Free Carbon by a Coulometric Method | 81 – 90 |
1.4This 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.
1.5This 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.
