    1. Scope

    1.1 This specification covers the requirements for ethylene glycol or propylene glycol base engine coolants used in automobiles or other light duty service cooling systems. When concentrates are used at 40 to 70 % concentration by volume in water, or when prediluted glycol base engine coolants 50 volume % or higher engine coolant concentrate are used without further dilution, they will function effectively to provide protection against freezing, boiling, and corrosion.

    1.2 The coolants governed by this specification are categorized as follows:

    Coolant Type

    Description

     

     

    I

    Ethylene glycol base concentrate

    II

    Propylene glycol base concentrate

    V

    Ethylene glycol base concentrate
    containing glycerin

     

     

    III

    Ethylene glycol predilute 50 volume % or higher engine coolant concentrate

    IV

    Propylene glycol predilute 50 volume % or higher engine coolant concentrate

    VI

    Ethylene glycol base predilute
    containing glycerin 50 volume % or higher engine coolant concentrate


    Note 1This specification is based on the knowledge of the performance of engine coolants prepared from new or virgin ingredients. This specification shall also apply to engine coolants prepared using glycol generated from recycled or reprocessed used coolant or reprocessed industrial-source glycol, provided that said glycol meets the requirements of Specification E1177. Separate specifications (D6471 and D6472) exist for engine coolants prepared from recycled or reprocessed used coolant or reprocessed industrial-source glycol that does not meet the requirements established in Specification E1177. This specification shall also apply to glycol based engine coolants prepared using fully refined glycerin provided that said glycerin meets the requirements for Specification D7640.

    1.3 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.

    1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    Note 2This specification applies to glycol base engine coolant for automobiles and light duty service. Specifications D4985 and D6210 exist for heavy duty engine service.
