Anotace textu normy ASTM D5752-25 :

This specification covers the general, physical, chemical, and performance requirements for supplemental coolant additives for use as precharging coolants in the cooling systems of heavy-duty engines. Test solutions shall be standard corrosive water, ethylene or propylene glycol in standard corrosive water, and NaCl dissolved in a solution of glycol in deionized water. These test solutions shall comply to the specific limits for the following requirements: corrosion in glassware mass loss; simulated service test mass loss; foaming; water pump cavitation erosion-corrosion rating; corrosion of cast aluminum alloys at heat-rejecting surfaces; ultrasonic cavitation resistance; supplemental coolant additive-glycol base coolant compatibility; hot surface scaling and deposits resistance; effect on nonmetals; storage stability; ash, chloride ion, and silicon contents; pH in distilled water; reserve alkalinity; and the effect on vehicle finish.
