1.1?This specification covers the requirements for ethylene glycol or propylene glycol or ethylene glycol containing glycerin base engine coolants used in automobiles or other light-duty service cooling systems. When concentrates are used at 40 % to 60 % concentration (allowance to 70 % concentration agreement between manufacturer and user) 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:
Note 1:?This 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 standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Note 2:?This specification applies to glycol base engine
coolant for automobiles and light-duty service. Specifications
D4985 and D6210 exist for heavy duty engine
service.
1.5?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
