Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). 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 established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on
the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information

INTERNATIONAL STANDARD ISO 21613:2015(E)
(U, Pu)O2 Powders and sintered pellets — Determination
of chlorine and fluorine
1 Scope
This International Standard describes a method for determining chlorine and fluorine in mixed (U,Pu)
−1
O powders and sintered pellets. It is applicable for the analysis of samples containing 5 µg.g to 50 µg.
−1 −1 −1
g of chlorine and 2 µg.g to 50 µg.g of fluorine.
For UO powder and sintered pellets, refer to ISO 22875.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO 3696, Water for analytical laboratory use — Specification and test methods
ISO 22875, Nuclear energy — Determination of chlorine and fluorine in uranium dioxide powder and
sintered pellets
ISO 9892, Uranium metal, uranium dioxide powder and pellets, and uranyl nitrate solutions — Determination
of fluorine content — Fluoride ion selective electrode method
3 Principle
The samples are pyrohydrolyzed at 850 °C – 1 000 °C in a tubular furnace with steam or moist oxygen.
Chlorine and fluorine are trapped as halogenated acids and entrained in an aqueous solution. Chloride
and fluoride ions are measured using selective electrodes or another appropriate method, for instance,
ionic chromatography.
4 Reagents
Use only reagents of recognized analytical grade.
4.1 Demineralised water, complying with at least grade 1 in accordance with ISO 3696 is recommended.
