Foreword

Rwanda Standards are prepared by Technical Committees and approved by Rwanda Standards Board (RSB) Board of Directors in accordance with the procedures of RSB, in compliance with Annex 3 of the WTO/TBT agreement on the preparation, adoption and application of standards.

The main task of technical committees is to prepare national standards. Final Draft Rwanda Standards adopted by Technical committees are ratified by members of RSB Board of Directors for publication and gazettment as Rwanda Standards.

DRS 121-1 was prepared by Technical Committee RSB/TC 001, Non-alcoholic beverages.

In the preparation of this standard, reference was made to the following standard (s):

1) KS 1054-1: 2008, Energy drinks — specification — Part 1: Ready-to-use energy drinks

The assistance derived from the above source is hereby acknowledged with thanks.

This second edition cancels and replaces the first edition (RS 121-1:2012), which has been technically revised.
