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 [   ], 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):  Other 
(HS 271019); Lubricating preparations (including cutting -oil preparations, bolt or nut 
release preparations,  anti-rust or anti -corrosion preparations and mould release 
preparations, based on lubricants) and preparations of a kind used for the oil or grease 
treatment of textile materials, leather, furskins or other materials, but excluding 
preparations containing , as basic constituents, 70% or more by weight of petroleum oils 
or of oils obtained from bituminous minerals (HS 3403); Wastes of metal pickling liquors, 
hydraulic fluids, brake fluids and anti -freeze fluids (HS 382550); Lubricants, industrial oils 
and re lated products (ICS 75.100)  
5. Title, number of pages and language(s) of the notified document:  
DUS-2159-3:2019, Hydraulic fluid — Performance Classifications — Part 3: Specifications 
for hydraulic fluids in categories HFAE, HFAS, HFB, HFC, HFDR and HFDU,  First Edition 
(20 page(s), in English)  
6. Description of content:  This Draft Uganda Standard specifies performance 
requirements, sampling and test methods for unused fire -resistant and less -flammable 
hydraulic fluids of the categories HFAE, HFAS, HFB, HFC, HFDR and HFDU, and is intended 
for hydrostatic and hydrodynamic systems in general industrial applications. This Draft 
Standard is not intended for use in aerospace or power -generation applications, where 
different requirements apply. Types HFAE, HFAS, HFB, HFC and HFDR are "fire -resistant" 
fluids as defined by DUS 215 9-1:2019. Most HFDU fluids, while displaying an 
improvement in combustion behaviour over mineral oil, fall outside this definition and are 
more appropriately considered "less -flammable" fluids.  
7. Objective and rationale, including 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  G/TBT/N/UGA/1115
