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 331: 2018 , Green gram  ― Specification , is identical with and has 
been reproduced from an International Standard, DEAS 331: 2018, Green gram ― Specification , and is being 
proposed for adoption as a Uganda Standard. 
This standard was developed by the Subcommittee on Cereals, pulses and related products , SC 3, under the 
Food and agriculture Standards Technical Committee (UNBS/TC 2 ). 
Wherever the wo rds, “ East African Standard " appear, they should be replaced by "Uganda Standard." 
This standard cancels and replaces the second edition, US EAS 331: 2013 , Sorghum grains  ― Specification , 
which has been technically revised. PUBLIC REVIEW DRAFT

 PUBLIC REVIEW DRAFT 
DEAS 331:2018 
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.
