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 Final Draft Uganda Standard, FDUS EAS 819: 2014 , Molasses for industrial use — Specification , is 
identical with  and has been reproduced from an East African  Standard , EAS 819: 2014, Molasses for 
industrial use  — Specification , and adopted  as a Uganda Standard.  
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 .  
FDEAS 819 was prepared by Technical Committee EAS/TC 0 19, Sugar and sugar confectionery.

shall be taken: 
a) The sampling instrument shall be clean and dry when used. 
b) The samples, the material being sampled the sampling instrument and the containers for samples 
shall be protected from adventitious contamination. DRAFT UGANDA STANDARD ON PUBLIC REVIEWFDEAS 819: 2014 
4 © EAC 2014  – All rights reserved  
 c) To draw a representative sample, the contents of each container selected for sampling shall be mixed 
as thoroughly possible by shaking or stilling or both, or by rolling so as to bring all portions into 
uniform distribution. 
d) The sample shall be placed in suitable clean, dry and air-tight metal or glass containers, on which the 
material has no action 
e) The sample containers shall be of such a size that they are almost, but not completely, filled by the 
sample. 
f) Each sample container shall be sealed airtight and market with full details of sampling and the date of 
sampling. 
g) Sampling can consists of a weighted metal cylinder with removable top, to which a rod is attached 
(see F igure.1). The cylinder is fasted to suitable rod. For tacking a sample, it is lowered in the tank to 
the required depth, and the top is removed with the help of the rod and the can then filled. 
 
For other containers, the sampling device of the design shown in Figure 2 may be used. DRAFT UGANDA STANDARD ON PUBLIC REVIEWFDEAS 814: 2014

Samples shall be drawn from each container/tanker as follows: 
Equal portions of the material shall be taken from different layers of the tank/tanker with the help of the 
sampling can to obtain a composite sample not less than 2.5 litres and mixed thoroughly in a suitable 
container. 
Divide this composite sample into three equal portions of not less than 750 mL in dried bottles or other 
containers, seal airtight and label with all the particulars of the sample. 
10.2.2 Supply in containers 
All the containers in a single consignment shall constitute a one lot. 
10.2.3 Gross sample. For the purpose of drawing samples for test a number of containers shall be selected

by shaking or stirring or both, or by rolling so as to bring all portions into uniform distribution. 
10.3.2 Drawing samples  
Samples shall be drawn by inserting the sampling device through the bung hole or any other convenient 
opening. Equal portions of the well-mixed material from each container in the gross sample shall be taken so 
as to obtain a quantity not less than 2.5 litres. The composite sample thus obtained shall be divided into three 
equal portions of not less than 750 mL in dried bottles or other containers, sealed airtight and labeled with all 
the particulars of the sample.

 Annex A 
(normativ e) 
 
Brix determination 
A.1 Brix determination by spindle method 
Determine the Brix by using an appropriate spindle 30 0C Baume- 60 0C Baum. Note the reading and the 
temperature from the thermometer attached to the base of the spindle. Apply the temperature correction and 
record the Brix at 20 0C. 
A.2 Brix determination by refractometer method 
Using a 50 % sample solution pipette a few mL through the clarity filter rubber teat pipette and pour onto the 
glass prism cover. Press the read function to take the reading. Multiply the reading by two to get the result.
