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 prepa rations 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 mo re by weight of petroleum oils or of oils 
obtained from bituminous minerals. (HS 3403). Lubricants, industrial oils and related 
products (ICS 75.100).  
5. Title, number of pages and language(s) of the notified document: DUS 2044:2018 
Standard test method f or determination of yield stress and apparent viscosity of used 
engine oils at low temperature, First Edition. (20 page(s), in English)   
6. Description of content: This Draft Uganda Standard covers the test method for the 
measurement of the yield stress a nd viscosity of engine oils after cooling at controlled 
rates over a period exceeding 45h to a final test temperature between -10°C and -40°C. 
The precision is stated for test temperatures from -40°C to -15°C. The viscosity 
measurements are made at a shear  stress of 525  Pa over a shear rate of 0.4  s-1 to 
15 s-1. This test method is suitable for measurement of viscosities ranging from 
4000 mPas to >400000  mPas, and is suitable for yield stress measurements of 7 Pa to 
>350 Pa.  This test method is applicable for used diesel oils. The applicability and precision 
to other used or unused engine oils or to petroleum products other than engine oils has 
not been determined.
