Standard Specification for Glycerin Base Engine Coolant for Automobile and Light-Duty Service

ABSTRACT
This specification covers the requirements for glycerin base engine coolants used in automobiles or other light duty service cooling systems. The requirements for engine coolant concentrates, prediluted glycerin base engine coolants, glycerin base coolant concentrates, and coolant concentrates include colour, effect on non-metals, relative density, and corrosion in glassware.
SCOPE
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:    
Coolant Type  
Description  
I  
Glycerin base concentrate  
II  
Glycerin predilute (50 to 60 volume %)
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 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. 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.

NOTE 3—Prediluted coolants are intended for direct addition to an engine cooling system with no further dilution. However, if circumstances require
addition and prediluted aqueous engine coolant is not available, use the appropriate engine coolant concentrate (Type I) diluted to 50 volume % with water
of at least the quality outlined in Table X1.1.
4.4 When diluting engine coolant concentrates for actual service, use municipal (treated) water, or low-mineral content well
water (see Appendix X1, Table X1.1). If such water is not available, use deionized (demineralized) or distilled water. This
procedure will minimize the formation of hard water scale and avoid the introduction of mineral components, such as chlorides
and sulfates, which can increase the corrosion rate of aluminum and iron.
4.5 When installed in accordance with the vehicle manufacturer’s recommendations and those on the product label, engine
coolant concentrates or prediluted glycerin base engine coolants shall be suitable for use in a properly maintained cooling system
(Appendix X1) in normal light-duty service for a minimum of one year without adversely affecting fluid flow and heat transfer.
5. Detailed Requirements
5.1 Glycerin base coolant concentrates and prediluted coolants shall be in accordance with the physical and chemical
requirements prescribed in Table 2 depending on coolant type (see 1.2).
5.2 The requirements listed in Table 2 for prediluted coolant (Type II) are prescribed for the coolant as packaged, without further
dilution or adjustment.

For purposes of determining conformance with this specification, an observed value shall be rounded “to the nearest unit” in the last right-hand digit used in expressing
the specification limit, in accordance with the rounding method of Practice E29.
