PART 7_DISTRIBUTION OF REFERENCE BIOLOGICAL STANDARDS AND BIOLOGICAL 

PREPARATIONS--Table of Contents

 

Sec. 7.3  Definitions.



    Biological standards means a uniform and stable reference biological 

substance which allows measurements of relative potency to be made and 

described in a common currency of international and national units of 

activity.

    Biological preparations means a reference biological substance which 

may be used for a purpose similar to that of a standard, but which has 

been established without a full collaborative study, or where a 

collaborative study has shown that it is not appropriate to establish 

the preparation as an international standard.
