ordinate the elaboration of standards and is  
(a) a member of International Organisatio n for Standardisation (ISO),  
(b) a contact point for the WHO/FAO Codex Alimentarius Commission on Food Standards, and  
(c) the National Enquiry Point on TBT Agreement of the World Trade Organisation (WTO).  
The work of preparing Uganda Standards is carried out through Technical Committees. A Technical 
Committee is established to deliberate on standards in a given field or area and consists of representatives of 
consumers , traders, academicians, manufacturers, government and other stakeholders.  
Draft Uganda Standards adopted by the Technical Committee are widely circulated to stakeholders and the 
general public for comments. The committee reviews the comments before recomm ending the draft standards 
for approval and declaration as Uganda Standards by the National Standards Council.  
This Draft Uganda Standard, DUS DEAS 1062 : 2021 , Pumpkin pulp flour — Specification , is identical with and 
has been reproduced from an East Af rican  Standard, EAS 1062 : 2021 , Pumpkin pulp flour — Specification , 
and adopted  as a Uganda Standard .

 Foreword  
Development of the East African Standards has been n ecessitated 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 exchange d 
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 
Standards Bodies in P artner 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, academi a, 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 finalizati on of standards, in 
accordance with the Principles and procedures for develop ment 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 versions of the standards 
they are implementing .  
The committee responsible  for this document is Te chnical Committee EASC/TC 025 , Processed fruits , 
vegetable s and tubers.  
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.
