Uganda National Bureau of Standards (UNBS) is a parastatal under the Ministry  of Tourism, Trade and 
Industry established under Cap 327, of the Laws of U ganda. 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 A limentarius Commission on Food Standards, and  
(c) the National Enquiry Point on TBT/SPS Agr eements 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 gi ven field or area and consists of representatives of 
consumers, traders, academician s, manufacturers, governme nt and other stakeholders. 
Draft Uganda Standards adopted by the Technical Committ ee 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 Final Draft Uganda Standard, FDUS EAS 762: 2011 , Dry soy beans  — Specification, is identical with  and 
has been reproduced from  an East African Standard, EAS 762: 2011 , Dry soy beans  — Specification, and is 
being proposed for adoption as a Uganda Standard.  
This standard was developed by the Food and agricu lture Standards Technical Committee (UNBS/TC 2).  
Wherever the words, “East Africa Standard" appear, they should be replaced by "Uganda Standard."  EAS 762:2011

Foreword 
 
Development of the East African Standards ha s been necessitated by the need for harmonizing 
requirements governing quality of products and services in East Africa. It is envisaged that through 
harmonized standardization, trade barriers which are encountered when goods and services are 
exchanged within the Comm unity will be removed.  
 In order to meet the above objectives, the EAC Partner States have enacted an East African 
Standardization, Quality Assurance, Metrology an d Test Act, 2006 (EAC SQMT Act, 2006) to make 
provisions for ensuring standardization, quality as surance, metrology and testing of products 
produced or originating in a third country and traded in the Community in order to facilitate industrial 
development and trade as well as helping to protect the health and safety of society and the 
environment in the Community. 
 
East African Standards are formulat ed in accordance with the proc edures established by the East 
African Standards Committee. The East Afri can Standards Committee is established under the 
provisions of Article 4 of the EAC SQMT Act, 2006. The Committee is composed of representatives of the National Standards Bodies in Partner States, t ogether with the representatives from the private 
sectors and consumer organizations. Draft East African Standards are circ ulated to stakeholders 
through the National Standards Bodies in the Pa rtner States. The comments received are discussed 
and incorporated before finalization of standards, in accordance with the procedures of the 
Community.   Article 15(1) of the EAC SQMT Act, 2006 provides t hat “Within six months of the declaration of an 
East African Standard, the Partner States shall adopt, without deviation from the approved text of the 
standard, the East African Standard as a nationa l standard and withdraw any existing national 
standard with similar scope and purpose”. 
 
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.

Introduction 
 
This standard has been developed to take into account: 
 
⎯ the needs of the market for the product;  
 
⎯ the need to facilitate fair domestic, regional and international trade and prevent technical barriers 
to trade by establishing a common trading language for buyers and sellers. 
 
⎯ the structure of the CODEX, UNECE, USA, ISO and other internat ionally significant standards; 
 
⎯ the needs of the producers in gaining knowle dge of market standards, conformity assessment, 
commercial cultivars and crop production process; 
 
⎯ the need to transport the product in a manner that  ensures keeping of quality until it reaches the 
consumer; 
 
⎯ the need for the plant protection authority to certif y, through a simplified form, that the product is 
fit for cross-border and international trade without carrying plant disease vectors; 
 ⎯ the need to promote good agricultural practi ces that will enhance wider market access, 
involvement of small-scale traders and hence making farming a viable means of wealth creation; 
and 
 
⎯ the need to ensure a reliable production base of consistent and safe crops that meet customer 
requirements.

For the purpose of this East African Stan dard, the following definitions shall apply. 
 
3.1 
soybeans 
whole mature dry seeds of varieties ( Glycine max (L.) Merr.)   
 
© EAC 2011 — All rights reserved  1 EAS 762:2011  
3.2 
colour 
Soybeans may be yellow, green, brown or black.  
 
3.3 
Damaged/defective grains soybeans and pieces of soybeans that ar e badly ground-damaged, badly weather-damaged, 
diseased, frost-damaged, germ-damaged, heat-d amaged, insect-bored, mould-damaged, sprout-
damaged, stinkbug-stung, or otherwise materially damaged. Stinkbug-stung kernels are considered 
damaged kernels at the rate of one-fourth of the actual percentage of the stung kernels. 
 3.4 
foreign matter   
 
any extraneous matter than dry soybeans or other food grains comprising of  
(a) "inorganic matter" includes metallic pieces, s hale, glass, dust, sand, gravel, stones, dirt,

 (b) "organic matter" consisting of detached seedc oats, straws, weeds and other inedible grains etc. 
 
3.5 
immature  
immature damaged soybeans are characterized by a green exterior appearance in conjunction with 
green discolouration penetrating the cotyledon. Examination of the cotyledons is determined by 
cutting the soybeans in cross section. For grading purposes, immature damaged soybeans are 
considered as part of the “Total Damage” grade sp ecification. Soybeans that  are green in appearance 
and have no discolouration of the cotyledon or ju st a halo of green around the outside of the 
cotyledon are to be assessed against th e overall colour of the sample.  
 
3.6 
poisonous, toxic and/or harmful seeds any seed which if present in quantities above pe rmissible limit may have damaging or dangerous 
effect on health, organoleptic properties or te chnological performance such as Jimson weed — 
dhatura ( D. fastuosa  Linn and D. stramonium  Linn.) corn cokle ( Agrostemma githago  L., Machai 
Lallium remulenum  Linn.) Akra (Vicia species), Argemone mexicana, Khesari and other seeds that 
are commonly recognized as harmful to health 
 
3.7 
rancid  
Soybeans in various stages of rancidity are characte rized by a deep pink discolouration on the seed 
coat and varying degrees of di scolouration of the cotyledon.  
 
3.8 splits  
broken soybean seeds that are less than three-quar ters of the whole seed, and cotyledons that are 
loosely held together by the seed coat.

percent of other grains for which standards have been established; 
 
b) shall be hard, clean, wholesome, uniform in  size, shape, colour and in sound merchantable 
condition;
