Uganda National Bureau of Standards (UNBS) is a parastatal under the Ministry of Trade, Industry and 
Cooperatives established under Cap 327, of the Laws of Uganda, as amended.  UNBS is mandated to co-
ordinate the elaboration of standards and is  
(a) a member of International Organisation for Standardisation (ISO) and  
(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 recommending the draft standards 
for approval and declaration as Uganda Standards by the National Standards Council.  
This Draft Uganda Standard, DUS DEAS 762: 2016, Dry soybeans  — Specification,  is identical with  and has 
been reproduced from a Draft East African Standard , DEAS 762: 2016, Dry soybeans  — Specification,  and is 
being proposed for adoption as a Uganda Standard. 
This third edition cancels and replaces the second edition US EAS 762:2014, Dry soybeans  — Specification , 
which has been technically revised.  
This standard was developed by the Food and agriculture Standards Technical Committee (UNBS/TC 2 ). 
Wherever the words, “ East African Standard" appear, they should be replaced by "Uganda Standard."

 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.  
In order to achieve this objective, the Community established an East African Standards Committee mandated 
to develop and issue East African Standards.   
The Committee is composed of representatives of the National Standards Bodies in Partner States, together 
with the representatives from the private sectors and consumer organizations. 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 procedures 
of the Community. 
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 .  
EAS 762 was prepared by Technical Commit tee EAS/ TC 014 , Cereals and pulses . 
This second/third/... edition cancels and replaces the first/second/... edition (EAS nnn-n:19xx), [clause(s) / 
subclause(s) / table(s) / figure(s) / annex(es)] of which [has / have] been technically revised.
