ASTM E1177-09

Standard Specification for Engine Coolant Grade Ethylene Glycol

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.
SCOPE
1.1 This specification covers commercial products, 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.
1.2 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. These types can be either redistilled or virgin.
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 and health practices and determine the applicability of regulatory limitations prior to use.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
