National foreword 
 
 
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 Internat ional Organisation 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  prepar ing  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 a nd 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 Uganda Standard, US EAS 1006: 2019, Sesame (simsim ) — Specification, is identical with and has 
been reproduc ed from an East African Standard, EAS 1006: 2019, Sesame (simsim) — Specification, and 
adopted as a Uganda Standard. 
 
The committee responsible for this document is Technical Committee UNBS/TC 2, Food and agriculture, 
Subcommittee SC 2, Edible oilseeds, fats and oils. 
 
Wherever the word s, “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, tra de 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  African  Standards  (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 Technical 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 thr ough the National Standards Bodies in 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 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 Technical Committee EASC/TC 015, Oil seeds, edible fats 
and oils. 
 
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.
