 Foreword  
Development of the East African Standa rds 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 service s are exchanged 
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 National 
Standard s 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 govern ment, 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 befo re finalization of 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 Standards are theref ore expected to ensure that they always have the latest versions of the standards 
they are implementing.  
EAS 889 was prepared by Technical Committee EASC/ TC/015, Edible Oil Seeds, Fats and Oils.  
This Second  edition cancels and replaces the First edition, which has been technically revised .
