Standard Specification for Low Silicate Ethylene Glycol Base Engine Coolant for Heavy Duty Engines Requiring a Pre-Charge of Supplemental Coolant Additive (SCA)

ABSTRACT
This specification covers the requirements for low silicate ethylene glycol base engine coolants for cooling systems of heavy-duty engines. Such engines are typically used in off-highway machinery for agriculture, mining, earth-moving, and construction; Class 5 to 8 over the road trucks and buses; high output stationary engine installations; and locomotive and marine installations. Prediluted coolants shall be prepared using deionized Ethylene glycol base engine coolant concentrates or prediluted ethylene glycol base engine coolants shall be formulated with ethylene glycol. The coolants shall conform to the prescribed physical, chemical, and performance requirements, which include relative density, freezing point, boiling point, ash content, pH, reserve alkalinity, water content, chloride ion content, silicon content, corrosion in glassware, simulated service test, foaming, and cavitation. The color and effect of nonmetals of the coolant shall be evaluated. Prediluted coolant shall also meet the required content of sulfate and iron. Its CaCO3 content shall be tested to determine its hardness.
SCOPE
1.1 This specification covers the requirements for low silicate ethylene glycol base engine coolants for cooling systems of heavy-duty engines. When concentrates are used at 40 % to 60 % concentration by volume in water, or when prediluted glycol base engine coolants (50 volume % minimum) are used without further dilution, they will function effectively to provide protection against corrosion, freezing to at least −36.4 °C (−33.5 °F), and boiling to at least 108 °C (226 °F).
Note 1: This specification is based on the knowledge of the performance of engine coolants prepared from new or virgin ingredients. A separate specification exists (Specification D6210) for heavy-duty engine coolants which may be prepared from recycled or reprocessed used coolant or reprocessed industrial-source ethylene glycol.  
1.2 Coolants meeting this specification require an initial charge of a supplemental coolant additive (SCA) and require regular maintenance doses of an SCA to continue the protection in certain operating 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's recommended instructions.  
1.3 The values stated in SI units are to be regarded as the standard. The values given 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
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.

ASTM D6660-01(2023)(Test Method)
Standard Test Method for Freezing Point of Aqueous Ethylene Glycol Base Engine Coolants by Automatic Phase Transition Method

SIGNIFICANCE AND USE
5.1 The freezing point of an engine coolant indicates the coolant freeze protection.  
5.2 The freezing point of an engine coolant may be used to determine the approximate glycol content, provided the glycol type is known.  
5.3 Freezing point as measured by Test Method D1177 or approved alternative method is a requirement in Specifications D3306 and D6210.  
5.4 This test method provides results that are equivalent to Test Method D1177 and expresses results to the nearest 0.1 °C with improved reproducibility over Test Method D1177.  
5.5 This test method determines the freezing point in a shorter period of time than Test Method D1177.  
5.6 This test method removes most of the operator time and judgement required by Test Method D1177.
SCOPE
1.1 This test method covers the determination of the freezing point of an aqueous engine coolant solution.  
1.2 This test method is designed to cover ethylene glycol base coolants up to a maximum concentration of 60 % (v/v) in water; however, the ASTM interlaboratory study mentioned in 12.2 has only demonstrated the test method with samples having a concentration range of 40 % to 60 % (v/v) water.
Note 1: Where solutions of specific concentrations are to be tested, they shall be prepared from representative samples as directed in Practice D1176. Secondary phases separating on dilution need not be separated.
Note 2: The products may also be marketed in a ready-to-use form (prediluted).  
1.3 The values stated in SI units are to be regarded as standard. No other 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 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. Some specific hazards statements are given in 7.3.  
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.

Standard Test Method for Compatibility of Supplemental Coolant Additives (SCAs) and Engine Coolant Concentrates

SIGNIFICANCE AND USE
5.1 This test was developed to mimic the formation of insolubles observed in some heavy-duty diesel cooling systems during the mid 1980s. It measures the compatibility of SCA and coolant concentrate solutions according to their tendency to form insolubles in service.3 Such insoluble materials may accumulate within a cooling system, restrict heat transfer through radiator cores, and contribute to the damage of components such as water pumps.
SCOPE
1.1 This test method covers determination of the compatibility of commercial SCA and commercial ethylene and propylene glycol engine coolant concentrates. This test method focuses on the solubility of specific chemical species formed in the engine coolant. The short duration of the test (24 h), among other restrictions, makes the test method of limited use for sorting out a variety of chemical compatibility problems in which a component of the SCA may react with a component of the coolant additive package. The test as currently written also does not deal with the issue of hard water compatibility, in which a component of the coolant or SCA additive package reacts with the hardness (Ca and Mg) to form a precipitate.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.  
1.3 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.  
1.4 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.
