1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

1.4 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 safeguard and safety hazard statements, see Section 6.

8.1 This test method covers the determination of free acid in plutonium nitrate solutions (4, 5).

16.1 This test method covers the determination of free acid in strong acid solutions of plutonium nitrate.

23.1 This test method covers the determination of uranium in the range from 300 to 3000 μg/g of plutonium in plutonium nitrate solutions.

34.1 This test method covers the determination of 10 to 150 μg of thorium per gram of plutonium in plutonium nitrate solutions.

43.1 This test method covers the determination of microgram quantities of iron in plutonium nitrate solutions.

51.1 This test method (9) is used to determine chloride in plutonium nitrate solution.

59.1 This test method covers the determination of microquantities of fluoride in plutonium nitrate solutions.

67.1 This test procedure covers the determination of the sulfate concentration in plutonium nitrate solutions in the range from 50 to 700 μg/g of plutonium.

75.1 This test method covers the determination of the isotopic content of nuclear-grade plutonium nitrate solutions.

77.1 This test method covers the determination of americium-241 in plutonium nitrate solutions.

86.1 This test method covers the determination of americium-241 in plutonium nitrate solutions that do not contain significant amounts of other radioactive fission products or high specific-activity gamma emitters.

95.1 This test method covers the determination of gamma-emitting fission products (for example, 95Zr-95Nb, 103Ru, 106Rh, and 137Cs-137mBa) and actinide impurities (232Th, 235U, and 238U) in plutonium nitrate. Test portions of plutonium nitrate are prepared to contain from 0.1 to 1.0 g of plutonium. The age of the plutonium after the last separation from actinides must be considered in calculating the actinide contents.

103.1 This test method covers the determination of rare earths in plutonium nitrate solutions in the range from 10 to 200 μg/g of plutonium.

106.1 This test method covers the determination of tungsten, niobium, and tantalum in plutonium nitrate solutions.

115.1 This test method covers the sample preparation for spectrographic analysis of plutonium nitrate for general metallic impurities by the carrier distillation test method.
