ASTM C791 : 12

Standard Test Methods for Chemical, Mass Spectrometric, and Spectrochemical Analysis of Nuclear-Grade Boron Carbide

Standard Details

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 in an Inductive Furnace and Infrared Measurement	7-16
Total Boron by Titrimetry and ICP OES	17-27
Isotopic Composition by Mass Spectrometry	28-32
Pyrohydrolysis	33-40
Chloride by Constant-Current Coulometry	41-49
Chloride and Fluoride by Ion-Selective Electrode	50-58
Water by Constant-Voltage Coulometry and Weight Loss on Drying	59-62
Metallic Impurities	63 and 64
Soluble Boron by Titrimetry and ICP OES	65-79
Free Carbon by a Coulometric Method	80-89
