Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard uses redrafted Law Amendment uses ISO 10980.1995 "Measurement of concentration of standard solution concentration with confirmation" (in English).
This standard and ISO 10980.1995 technical differences exist compared to the terms of these differences has been involved through its outer margin bits
Opposing vertical single line (︱) were indicated in Appendix I are given a list of corresponding technical differences and their causes.
This standard and ISO 10980.1995 compared to the main technical differences are as follows.
--- Standard name changed to "uranium, plutonium, and the concentration of potassium dichromate standard solution confirmation";
--- Uranium metal in Appendix A to the standard substance Triuranium reference material, and the corresponding modification of the preparation procedure;
--- Appendix B of plutonium metal reference material to plutonium dioxide plutonium reference materials, and modify the corresponding preparation procedures;
Local --- numerical example of the re-calculated, for example, a standard text (this standard) in 4.3.5,5.4, Appendix E, Appendix F and attached

Confirm uranium, plutonium and potassium dichromate standard solution concentration
1 Scope
This standard specifies the procedure for preparing the uranium, plutonium, and potassium dichromate standard solution and confirm its concentration program.
This standard applies to confirm the uranium, plutonium and preparation and concentration of potassium dichromate standard solution preparation and concentration of other substances in the standard solution
Confirm also refer to use.

Principle 3
Uranium, plutonium and potassium dichromate standard solution independently prepared. There are prepared using certified reference materials or high-purity uranium material, plutonium and standard potassium dichromate solution
Solution. accurately weighed these substances completely dissolved, the obtained solution was accurately weighed, calculated according to the known solution composition weighing data and reference material
concentration.
With analysis of these solutions can be compared with each other between the inspection accuracy of the prepared solution concentration, so that the computed
Relative deviation from the average concentration between repeated measurements is less than a certain limit. The reference material according preparing solutions
Level, the standard solution can be in two grades.
--- A standard solution;
--- Secondary standard solution.
4 a standard solution
4.1 Overview
Procedures for preparing uranium, plutonium, and a standard solution of potassium dichromate, respectively, see Appendix A, Appendix B and Appendix C. A standard solution can be used
Calibration or confirm the concentration of secondary standard solution.
4.2 The purpose of the confirmation process
The purpose of the validation process is to ensure that the error does not occur in abnormal use certified reference material solution preparation process. When a prepared
Grade standard solution, the result by the standard of quality and quality of substance solution obtained is called the calculated concentration; use another one standard solution
