5. Title, number of pages and language(s) of the notified document:  DUS 2426:2021, 
Standard Specification for Low Silicate Ethylene Glycol Base Engine Coolant for Heavy 
Duty Engines Requiring a Pre -Charge of Supplemental Coolant Additive (SCA), First 
Edition (12 pag e(s), in English)  
6. Description of content:  This Draft Uganda Standard covers the requirements for low 
silicate ethylene glycol base engine coolants for cooling systems of heavy -duty engines. 
When concentrates are used at 40 to 60  % concentration by volu me in water, or when 
prediluted glycol base engine coolants (50 volume % minimum) are used without further 
dilution, they will function effectively to provide protection against corrosion, freezing to 
at least −36.4°C (−33.5°F), and boiling to at least 108 °C (226°F).  
7. Objective and rationale, including the nature of urgent problems where 
applicable:  Prevention of deceptive practices and consumer protection; Quality 
requirements  G/TBT/N/UGA/1448
