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

1.2 The analytical procedures appear in the following order:

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 and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section .

1.3 This test method covers the loss-on-ignition of volatile constituents from nuclear-grade gadolinium oxide (Gd2O 3) powder.

1.4 The percent gadolinium oxide content of powders, exclusive of volatiles, is determined by calculation after the material has been analyzed to determine the total impurities.
