1.1?This specification covers the requirements for glycerin base engine coolants used in automobiles or other light duty service cooling systems. When concentrates are used at 50 % to 60 % concentration by volume in water, or when prediluted glycerin base engine coolants (50 volume % minimum) 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 that comply with 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. See X1.5 and X3.1.3 for specific warning statements. Note 2:?This specification applies to automobiles and light
duty service. A glycerin based specification for heavy duty engine
service is under development.
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. |
