NOTIFICATION  
The following notification is being circulated in accordance with Article 10.6  
 
1. Notifying Member: UGANDA   
If applicable, name of local government involved (Article 3.2 and 7.2):   
2. Agency responsible: Uganda National Bureau of Standards  
Name and address (including telephone and fax numbers, email and website 
addresses, if available) of agency or authority designated to handle comments 
regarding the notification shall be indicated if different from above:   
3. Notified under Article 2.9.2 [X], 2.10.1 [   ], 5.6.2 [ X], 5.7.1 [   ], other:  
4. Products covered (HS or CCCN where applicable, otherwise national tariff 
heading. ICS numbers may be provided in addition, where applicable): Carbon 
reinforced polymer bars, Glass fibre reinforced polymer bars; Polymers of ethylene, in 
primary forms. (HS 3 901), - Cyclic polymers of aldehydes (HS 291250). Reinforced 
plastics (ICS 83.120).  
5. Title, number of pages and language(s) of the notified document: DUS 2093: 
2018, Carbon and Glass Fibre Reinforced Polymer bar materials for concrete 
reinforcement - Specification, First Edition (18 page(s), in English)    
6. Description of content: This Draft Uganda Standard describes permitted constituent 
materials, limits on constituent volumes, and minimum performance requirements for 
carbon and glass fibre reinforce d polymer (FRP) bars to be used as reinforcement for 
non-pre-stressed concrete. Only carbon and Glass FRP bars are covered by this 
specification. FRP bars made of more than one fibre type (hybrid FRP) are not covered by 
this specification. Pultruded FRP ba rs with no external surface enhancement (that is, plain 
or smooth bars) to facilitate bond with concrete are not covered by this specification. 
Similarly, hollow FRP bars are not considered due to lack of documented performance as 
reinforcement for concret e. Plain FRP bars used as dowels (that is, devices that transfer 
shear across concrete joints) where the intended function requires slip of the dowel are 
not covered by this specification.  
This specification does not cover pre -manufactured grids and gratings made with FRP 
materials. FRP mats resulting from assembly of deformed FRP bars, however, are covered 
by this document. The specification also does not cover FRP bars when used for external 
and near -surface -mounted strengthening applications. The t ext of this specification 
references notes and footnotes that provide explanatory material. These notes and 
footnotes (excluding those in tables and figures) shall not be considered as requirements 
of the specification  
7. Objective and rationale, includin g the nature of urgent problems where 
applicable: Consumer information, labelling; Prevention of deceptive practices and 
consumer protection; Protection of human health or safety; Quality requirements;
