ASTM C967-12

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Uranium Ore Concentrate
This standard is issued under the fixed designation C967; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
This specification is intended to provide the nuclear industry with a general standard for uranium
ore concentrate. Material conforming to this specification will generally meet the requirements for
conversion to uranium hexafluoride. However, the converter may relax or supplement this specifica-
tion upon mutual agreement with the customer.
1. Scope
1.1 This specification covers uranium ore concentrate containing a minimum of 65 mass % uranium.
1.2 This specification does not include requirements for health and safety. Observance of this specification does not relieve the
user of the obligation to be aware of and conform to all applicable international, national, state, and local regulations pertaining
to possessing, shipping, or using source nuclear material (see 2.2).
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
