 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 throug h 
harmoniz ed standardization, trade barriers that are encountered when goods and services are exchanged  
within the Community will be removed.  
The Community has established an East African Standards Committee (EASC) mandated to develop and 
issue East Afric an Standar ds (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 Te chnical 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 Standard s Bodies i n the 
Partner States. The comments received are discussed and incorporated before 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 p ace with technological advances. Users of the East 
African Standards are therefore expected to ensure that they always have the latest versions of the standards 
they are implementing.  
The committee responsible for this document is Technical Commi ttee EASC/ TC 017, Milk and milk products . 
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.  
This fourth  edition  (DEAS 49:  2022) cancels and replaces the third edition (EAS 49: 2019), which has been 
technically revised.
