 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 International Organisation for Standardisation (ISO) ;  
(b) a contact point for the WHO/FAO C odex 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 key stakeholders 
including government, academia, consumer groups, pri vate sector and other interested parties.  
Draft Uganda Standards adopted by the Technical Committee are widely circul ated 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.  
The committee responsible for this docu ment is Technical Committee UNBS/TC 315, Textiles and related 
products.
