ASTM C696-11<\/h3>\n

Historical Standard: Standard Test Methods for Chemical, Mass Spectrometric, and Spectrochemical Analysis of Nuclear-Grade Uranium Dioxide Powders and Pellets<\/h4>\n
\n

ASTM C696<\/h4>\n

Scope<\/strong><\/p>\n

1.1 These test methods cover procedures for the chemical, mass spectrometric, and spectrochemical analysis of nuclear-grade uranium dioxide powders and pellets to determine compliance with specifications.<\/p>\n

1.2 The analytical procedures appear in the following order:<\/p>\n

7.1 This test method covers the determination of moisture in uranium dioxide samples. Detection limits are as low as 10 \u03bc<\/span>g.<\/p>\n

15.1 This test method covers the determination of nitride nitrogen in uranium dioxide in the range from 10 to 250 \u03bc<\/span>g.<\/p>\n

23.1 This test method covers the spectrographic analysis of nuclear-grade UO2<\/sub> for the 26 elements in the ranges indicated in Table 1.<\/p>\n

23.2 For simultaneous determination of trace elements by plasma emission spectroscopy refer to Test Method C761.<\/p>\n

TABLE 1 Recommended Analytical Spectral Lines and Concentration Range of Trace Elements<\/p>\n

A<\/span><\/sup> All of the above lines are photographed in the second order, except barium and calcium which are first order lines.<\/p>\n

B<\/span><\/sup> A gallium oxide carrier must be used for silver. See Test Method E402.<\/p>\n

31.1 This test method covers the spectrochemical determination of silver in nuclear-grade uranium dioxide. The relative standard deviation is 15 % for the concentration range of 0.1 to 50 \u03bc<\/span>g\/g.<\/p>\n

33.1 This procedure is designed for a rapid determination of surface area of nuclear-grade uranium dioxide (UO2<\/sub>) powders. The determination of surface area by this procedure is automatic, simple, and fast enough to be used in quality control work. The range of analysis is from 1 to 1500 m2<\/sup>\/g.<\/p>\n
