Anotace textu normy ASTM D4985-10(2023) :
This specification covers the requirements for low silicate ethylene glycol base engine coolants for cooling systems of heavy-duty engines. Such engines are typically used in off-highway machinery for agriculture, mining, earth-moving, and construction; Class 5 to 8 over the road trucks and buses; high output stationary engine installations; and locomotive and marine installations. Prediluted coolants shall be prepared using deionized Ethylene glycol base engine coolant concentrates or prediluted ethylene glycol base engine coolants shall be formulated with ethylene glycol. The coolants shall conform to the prescribed physical, chemical, and performance requirements, which include relative density, freezing point, boiling point, ash content, pH, reserve alkalinity, water content, chloride ion content, silicon content, corrosion in glassware, simulated service test, foaming, and cavitation. The color and effect of nonmetals of the coolant shall be evaluated. Prediluted coolant shall also meet the required content of sulfate and iron. Its CaCO3 content shall be tested to determine its hardness.
