1、Designation: D7713 11Standard Specification forAqueous Engine Coolant Grade Glycol (53% Nominal)1This standard is issued under the fixed designation D7713; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision.
2、A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers both commercial products,engine coolant grade ethylene glycol and propylene glycol,including virgin glycols
3、 and those derived from the recyclingof vehicle engine coolants and industrial source glycols.1.2 Types EG-1 and PG-1 cover glycols with sufficientlylow limits on components to allow a blended coolant to meetmost OEM (Original Equipment Manufacturer) specifications.These types will probably be virgi
4、n materials, although redis-tillation could produce a sufficiently pure product. Types EG-2and PG-2 cover glycol that will be suitable for many coolants.These types can be either redistilled or virgin.1.3 The values stated in SI units are to be regarded asstandard. No other units of measurement are
5、included in thisstandard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations pri
