 Foreword  
Development of the East A frican Standards  has been neces sitated 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 good s and services a re ex changed 
within the Community will be removed.  
The Community 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 Nat ional 
Standards Bodie s in Partn er 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 in cluding governme nt, academia, c onsumer 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 inc orporated before  finalization o f standards, in 
accordance with the Principles 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 Stand ards are therefo re ex pected to ensure that they always have the latest versions of the standards 
they are implementing .  
The committee responsible for this document is Technical Committee EASC/TC 015, Oil seeds, edible fats 
and oils .  
Attention is drawn to  the possibility  that some of t he elements of this document may be subject of patent
