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.
