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 [   ], 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): Engine 
oils; 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 b asic constituents, 70% or more by weight of petroleum oils or of oils 
obtained from bituminous minerals. (HS 3403). Lubricants, industrial oils and related

5. Title, number of pages and language(s) of the notified document: 
FDUS  2082:2018 Standard Test Method for Measuring Apparent Viscosity at 
High-Temperature and High -Shear Rate by Multicell Capillary Viscometer, First Edition. 
(14 page(s), in English)    
6. Description of content: This Draft Uganda Standard covers the test method for the 
laboratory determination of high -temperature high -shear (HTHS) viscosity of engine oils 
at a temperature of 150  °C using a multicell capillary viscometer containing pressure, 
temperature, and timing instrumentation. The shear rate for this test met hod corresponds 
to an apparent shear rate at the wall of 1.4 million reciprocal seconds (1.4  × 10 6 s−1).  
7. Objective and rationale, including the nature of urgent problems where 
applicable: Prevention of deceptive practices and consumer protection; Harmonization
