The work of preparing International Standards is normally carried out through IsO technical committees. Each member body interested in a subject for which a technical committee has been non-governmental, in liaison with IsO, also take part in the work. IsO collaborates closely y with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/lEc Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval byat least 75% of thememberbodies casting avote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. IsO shall not be held responsible for identifying any or all such patent rights. ISO 13465 was prepared by Technical Committee ISO/TC 85, Nuclear energy,Subcommittee SC 5, Nuclear fuel technology. This second edition cancels and replaces the first edition (isO 13465:1997), which has been technically revised. ili ISO13465:2009(E) Introduction This International s Standard specifies an analytical method for determining the neptunium concentration in controls at the different steps of the process in a nuclear fuel reprocessing plant. @ ISO 2009 - All rights reserved itted without ficense from IHS Not for Resale INTERNATIONAL STANDARD ISO13465:2009(E) neptunium in nitric acid solutions by spectrophotometry 1 Scope This International Standard specifies an analytical method for determining the neptunium concentration by spectrophotometry,withastandard deviationof about5%,innitric acid solutionsafterthe dissolution of method is applicable to aliquots containing a concentration of neptunium between 10 mg-1-1 and 200 mg-1-1 2 Normative references The following referenced documents are indispensable for the application of this document.
