Description

ASTM C696-11

Historical Standard: Standard Test Methods for Chemical, Mass Spectrometric, and Spectrochemical Analysis of Nuclear-Grade Uranium Dioxide Powders and Pellets

ASTM C696

Scope

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.

1.2 The analytical procedures appear in the following order:

7.1 This test method covers the determination of moisture in uranium dioxide samples. Detection limits are as low as 10 μg.

15.1 This test method covers the determination of nitride nitrogen in uranium dioxide in the range from 10 to 250 μg.

23.1 This test method covers the spectrographic analysis of nuclear-grade UO₂ for the 26 elements in the ranges indicated in Table 1.

23.2 For simultaneous determination of trace elements by plasma emission spectroscopy refer to Test Method C761.

TABLE 1 Recommended Analytical Spectral Lines and Concentration Range of Trace Elements

^A All of the above lines are photographed in the second order, except barium and calcium which are first order lines.

^B A gallium oxide carrier must be used for silver. See Test Method E402.

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 μg/g.

33.1 This procedure is designed for a rapid determination of surface area of nuclear-grade uranium dioxide (UO₂) 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/g.
