DUS 2396:2021, Standard Specification for Fully-Formulated Glycol Base Engine Coolant for Heavy-Duty Engines, First edition (8 page(s), in English)
This specification covers the requirements for fully-formulated glycol base coolants for cooling systems of heavy-duty engines. When concentrates are used at 40 to 60 % glycol concentration by volume in water of suitable quality, (see Appendix X1), or when prediluted glycol base engine coolants (50 volume % minimum) are used without further dilution, they will function effectively during both winter and summer to provide protection against corrosion, cavitation, freezing, and boiling.
