4.1 This test method may be run together with Test Method C1432 to analyze for trace impurities in Pu metal. Using the technique described in this test method and the technique described in Test Method C1432 will provide the analyst with a more thorough verification of the impurity concentrations contained in the Pu metal sample. In addition, Test Method C1432 can be used to determine impurity concentrations for analytes such as Ca, Fe, Na, and Si, which have not been determined using this test method.
4.3 This test method has been validated for use on materials that meet the specifications described in Specification C757 and Test Methods C758 and C759.
4.4 This test method has been validated for all elements listed in Table 1.
