1.1 These 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.
1.2 The analytical procedures appear in the following order:
| Sections | |
| Total Carbon by Combustion and Gravimetry | 7-17 |
| Total Boron by Titrimetry | 18-28 |
| Isotopic Composition by Mass Spectrometry | 29-38 |
| Chloride and Fluoride Separation by Pyrohydrolysis | 39-45 |
| Chloride by Constant-Current Coulometry | 46-54 |
| Fluoride by Ion-Selective Electrode | 55-63 |
| Water by Constant-Voltage Coulometry | 64-72 |
| Impurities by Spectrochemical Analysis | 73-81 |
| Soluble Boron by Titrimetry | 82-95 |
| Soluble Carbon by a Manometric Measurement | 96-105 |
| Metallic Impurities by a Direct Reader Spectrometric Method | 106-114 |
