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.

ABSTRACT
This specification establishes the testing and requirements of four types of engine coolant grade ethylene glycol and propylene glycol, including virgin glycols and those derived from the recycling of vehicle engine coolants and industrial source glycols. Types EG-1 and PG-1 cover glycols with sufficiently low limits on components to allow a blended coolant to meet most OEM (Original Equipment Manufacturer) specifications. These types will probably be virgin materials, although redistillation could produce a sufficiently pure product. Types EG-2 and PG-2 cover glycol that will be suitable for many coolants, and can either be redistilled or virgin. The commercial products shall be suitably sampled and tested, and shall conform accordingly to specified values of the following physical and chemical properties: clarity; color (Pt/Co scale); relative density; pH by volume in distilled water; acidity as acetic acid; composition by mass of individual glycols (including ethylene glycol, propylene glycol, dipropylene glycol, and others); total composition by mass of all glycols; water content; glycol ester content; and the maximum content for nitrites, nitrates, phosphates, silicon, chloride, sulfate, boron, aluminum, calcium, copper, iron, magnesium, lead, zinc, and iron.

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).

This test method was originally developed to determine the purity of 1,3-propanediol used for the application as the freeze point depressant base fluid in formulated PDO engine coolants. Use of the method for purity of PDO for other applications may be viable.

ABSTRACT
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 % glycol concentration by volume in water of suitable quality, or when prediluted glycol 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.

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

ABSTRACT
This specification establishes the testing and requirements of four types of engine coolant grade ethylene glycol and propylene glycol, including virgin glycols and those derived from the recycling of vehicle engine coolants and industrial source glycols. Types EG-1 and PG-1 cover glycols with sufficiently low limits on components to allow a blended coolant to meet most OEM (Original Equipment Manufacturer) specifications. These types will probably be virgin materials, although redistillation could produce a sufficiently pure product. Types EG-2 and PG-2 cover glycol that will be suitable for many coolants, and can either be redistilled or virgin. The commercial products shall be suitably sampled and tested, and shall conform accordingly to specified values of the following physical and chemical properties: clarity; color (Pt/Co scale); relative density; pH by volume in distilled water; acidity as acetic acid; composition by mass of individual glycols (including ethylene glycol, propylene glycol, dipropylene glycol, and others); total composition by mass of all glycols; water content; glycol ester content; and the maximum content for nitrites, nitrates, phosphates, silicon, chloride, sulfate, boron, aluminum, calcium, copper, iron, magnesium, lead, zinc, and iron.

SIGNIFICANCE AND USE
Knowledge of an approved method is required to establish whether the product meets the requirements of its specifications. The use of glycols in the reference sample is not intended to suggest the presence of glycol (EG, PG and DPG) impurities, but to demonstrate and quantify the separation of commonly used Engine Coolant glycols from PDO.
SCOPE
1.1 This test method describes the gas chromatographic determination of purity for 1,3-propanediol (PDO). This test method was originally developed to determine the purity of 1,3-propanediol used for the application as the freeze point depressant base fluid in formulated PDO engine coolants. Use of the method for purity of PDO for other applications may be viable.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
