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

Standard Test Method f or Apparent Viscosity of Engin e Oils and Base Stocks 
Between -10°C and -35°C Using Cold -Cranking Simulator, First Edition. (19 page(s), in 
English)   
6. Description of content: This Draft Uganda Standard covers the test method for the 
laboratory determinat ion of apparent viscosity of engine oils and base stocks by cold 
cranking simulator (CCS) at temperatures between -10°C and -35°C at shear stresses of 
approximately 50  000 Pa to 100  000 Pa and shear rates of approximately 105 to 104 s -1 
for viscosities of approximately 900  mPa·s to 25 000 mPa ·s. The range of an instrument 
is dependent on the instrument model and software version installed. Apparent Cranking 
Viscosity results by this method are related to engine -cranking characteristics of engine 
oils. 
7. Objective and rationale, including the nature of urgent problems where 
applicable: Prevention of deceptive practices and consumer protection; Harmonization
