ASTM D7517-19

Annotation of standard text ASTM D7517-19 :

This specification covers the requirements for fully formulated glycol base engine coolants intended for use in the cooling systems of heavy-duty engines. The coolants governed by this specification are categorized as follows: propanediol base concentrate and prediluted propanediol. The coolants shall provide protection in operating engines against cavitation corrosion (also termed as liner pitting) and internal engine hot surface scaling. Hot surfaces typically are within the engine head, head spacer, upper cylinder liner, or liquid cooled exhaust manifold. Both the concentrated and prediluted coolants shall meet the sulfate ion content requirement.
