Anotace textu normy ASTM D7713-18(2023) :

This specification covers both commercial products, engine coolant grade ethylene glycol and propylene glycol, including virgin glycols and those derived from the recycling of vehicle engine coolants and industrial source glycols. Types EG-1 and PG-1, which will probably be virgin materials, cover glycols with sufficiently low limits on components to allow a blended coolant to meet most Original Equipment Manufacturer (OEM) specifications. Types EG-2 and PG-2, on the other hand, can be either redistilled or virgin. These cover glycol that will be suitable for many coolants.
