1.1 These test methods cover procedures for the chemical and mass spectrographic analysis of nuclear-grade gadolinium oxide powders to determine compliance with specifications.

1.2 The analytical procedures appear in the following order:

Sections Carbon by Direct Combustion---Thermal Conductivity 7 to 16 Total Chlorine and Fluorine by Pyrohydrolysis Ion- 17 to 23 Selective Electrode Loss of Weight on Ignition 24 to 30 Sulfur by Combustion---Iodometric Titration 31 to 38 Impurity Elements by a Spark-Source Mass Spectrographic 39 to 45 Gadolinium Content in Gadolinium Oxide by Impurity 46 to 49 Correction

1.2 This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
