Concentrated f lavoured drink s -Specification  
  
 0. Foreword  
 Concentrated  flavoured  drinks  are popular  beverages  used  as refreshment  and are 
presented  in different  brands/types  in the market.   
This Tanzania  Standard  was prepared  in order  to ensure  that the Concentrated  
flavoured  drinks  prepared,  produced  and imported  in the country  are safe and of good  
quality.  
In the preparation  of this Tanzania  Standard  considerable  assistance  was drawn  from 
concentrated  flavoured  drinks  manufacturers  and from KS 1485:2018 , Water  based  
flavoured  drinks  published  by the Kenya  Bureau  of Standards  
In reporting  the results  of test or analysis  made  in accordance  with this Tanzania  
Standard,  if the final value  observed  or calculated  is to be rounded  off, it shall be done  
in accordance  with TZS 4 (see clause  2).
