1、Designation: D7713 12D7713 18Standard Specification forAqueous Engine Coolant Grade Glycol (53% (53 % byVolume 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
2、year of last revision. 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,
3、 includingvirgin glycols and those derived from the recycling of vehicle engine coolants and industrial source glycols.1.2 Types EG-1 and PG-1 cover glycols with sufficiently low limits on components to allow a blended coolant to meet mostOEM (Original Equipment Manufacturer) specifications. These t
4、ypes will probably be virgin materials, although redistillationcould produce a sufficiently pure product. Types EG-2 and PG-2 cover glycol that will be suitable for many coolants. These typescan be either redistilled or virgin.1.3 The values stated in SI units are to be regarded as standard. No othe
5、r units of measurement are included in this standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety safety, health, and healthenvironmental practices and d
6、etermine theapplicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardizationestablished in the Decision on Principles for the Development of International Standards, Guides and Recommendatio

All laboratories were asked to report three test results from a single operator,for
29、 every material. Except for the inability of all participants to report all requested replicates, Practice E691 was followed for thedesign and analysis of the data; the details are given in ASTM Research Report No. D15-XXXX.36.1.1 Repeatability limit (r)Two test results obtained within one laborator
