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

(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 stan dards in a given field or area and consists of key stakeholders 
including government, academia, consumer groups, private sector and other interested parties.  
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.  
The committee responsible for this document is Technical Comm ittee UNBS /TC 7, Textile, Leather, Paper and

 Introduction  
The national  flag symb olizes  national  integrity,  unity  and sovereignty.  It also characterizes  patriotism  of a 
nation and it has been the  grass  root of political freedom.  
For the case  of Uganda,  the National  and Armorial  Ensigns  Act of 1962  (Cap.  254) specifies  the basic  
require ments  of the Uganda  flag in terms  of colour,  band width  and location  of a crested  crane.  It does  not 
specify the performance  of the flag  in terms of dimensional requirements, quality of material and hues.  
Over  a time,  various  types  of flags  have  also been  produced  like the internal  flag, external  flag, hand -held 
flag and desk flag, but the  Act does not  take into  account these various  types of  flags and as such all  are 
classified  as one entity though  their performance requirements  may be different depending  on the conditions  
of use.  
This Uganda  standard  seeks  to support  the national  legislation  on the flag to ensure  that the Uganda  flag is 
fully standardized  in terms  of performance  and quality  of material.  This will lead to ease  of production  and 
interchangeab ility between  different suppliers.
