ASTM D7517-19

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D7517 − 09 (Reapproved 2014) D7517 − 19
Standard Specification for
Fully-Formulated 1,3 Propanediol (PDO) Base Engine
Coolant for Heavy-Duty Engines
This standard is issued under the fixed designation D7517; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope Scope*
1.1 This specification covers the requirements for fully-formulated glycol base coolants for cooling systems of heavy-duty
engines. When concentrates are used at 40 to 60 % PDO concentration by volume in water of suitable quality, (see Appendix X1),
or when prediluted PDO base engine coolants (50 volume % minimum) are used without further dilution, they will function
effectively during both winter and summer to provide protection against corrosion, cavitation, freezing, and boiling.
1.2 The coolants governed by this specification are categorized as follows:
Coolant Type Description
I-FF 1,3 Propanediol base concentrate
II-FF 1,3 Propanediol predilute (50 vol %)
1.3 Coolant concentrates meeting this specification do not require any addition of Supplemental Coolant Additive (SCA) until
the first maintenance interval when a maintenance dose of SCA is required to continue protection in certain heavy-duty engine
cooling systems, particularly those of the wet cylinder liner-in-block design. The SCA additions are defined by and are the primary
responsibility of the engine manufacturer or vehicle manufacturer. If they provide no instructions, follow the SCA
supplier’ssupplier’s instructions.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
after SI units are provided for information only and are not considered standard.
1.5 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 safety, health, and healthenvironmental practices and determine the
applicability of regulatory limitations prior to use.
1.6 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.

3. Terminology
3.1 Definitions:
3.1.1 supplemental coolant additive (SCA), n—an additive used in conventionally inhibited heavy-duty engine coolants required
to maintain protection against general corrosion, cylinder liner pitting, and scaling in heavy-duty engines.
3.1.2 For other definitions used in this specification, refer to Terminology D4725.
4. General Requirements
4.1 Concentrated and prediluted coolants shall meet all of the respective requirements of Specification D7518.
4.2 The coolant concentrate mixed with water or the prediluted coolant, when maintained with maintenance doesdoses of SCA
in accordance with the engine manufacturer’smanufacturer’s recommendations, and those on the product label, shall be suitable
for use in a properly maintained cooling system in normal service for a minimum of two years (See(see Appendix X1).
5. Additional Requirements
5.1 The coolant concentrate or prediluted coolant additionally shall provide protection in operating engines against cavitation
corrosion (also termed liner pitting) and against scaling of internal engine hot surfaces. Hot surfaces typically are within the engine
head, head spacer, upper cylinder liner, or liquid cooled exhaust manifold. ASTMAnnex A1 has test methods under development
for both cavitation corrosion and hot surface scaling. Until these procedures are approved as ASTM standards, the mandatory
requirements of details requirements that Annex A1shall apply.be met.
5.2 Lack of compatibility between the coolant and SCA product’s chemistry may cause the solute to precipitate out of solution,
with potential adverse effects in the vehicle or engine cooling system. A test procedure for compatibility (Test Method D5828) has
been developed and approved. The compatibility of SCA and coolant concentrate solutions meeting this specification shall be
determined using Test Method D5828 and the results reported. ASTM Committee D15 has not determined a pass/fail limit for this
test. Limits are to be agreed upon between customer and supplier.
5.3 Both the concentrated and prediluted coolants shall contain less than 50 μg/g sulfate ion.
