Foreword  
 
Development of the East African Standards has been necessitated by the need for harmonizing requirements  
governing quality of products and services in the East African Community. It is envisaged that through  
harmonized standardization, trade barriers that are encountered when goods and services are exchanged  
within  the Community  will be removed.  
 
The Communit y has established an East African Standards Committee (EASC) mandated to develop and  
issue  East African  Standards  (EAS).  The Committee  is composed  of representatives  of the National  
Standards Bodies in Partner States, together with the representatives from  the public and private sector  
organizations in  the community.  
 
East African  Standards  are developed  through  Technical  Committees  that are representative  of key 
stakeholders including government, academia, consumer groups, private sector and other interested parties.  
Draft East African Standards are circulated to stakeholders through the National Standards Bodies in the  
Partner States. The comments received are discussed and incorporated before finalization of standards, in  
accordance with  the Princ iples and  procedures  for development  of East  African  Standards.  
 
East African Standards are subject to review, to keep pace with technological advances. Users of the East  
African Standards are therefore expected to ensure that they always have the latest v ersions of the standards  
they are implementing . 
 
The committee  responsible  for this document  is Technical  Committee  EASC/TC  014, Cereals  and pulses.  
 
Attention  is drawn  to the possibility  that some  of the elements  of this document  may be subject  of patent  
rights. EAC  shall not be held responsible  for identifying  any or all such  patent rights.
