(Specification)Standard Specification for Aqueous Engine Coolant Grade Glycol (53 % by Volume Nominal)
Standard Specification for Aqueous Engine Coolant Grade Glycol (53 % by Volume Nominal)
ABSTRACT
This specification covers both 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. Types EG-1 and PG-1, which will probably be virgin materials, cover glycols with sufficiently low limits on components to allow a blended coolant to meet most Original Equipment Manufacturer (OEM) specifications. Types EG-2 and PG-2, on the other hand, can be either redistilled or virgin. These cover glycol that will be suitable for many coolants.
SCOPE
1.1 This specification covers both 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 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.
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.

Overview
ASTM D7713-18(2023) is the standard specification established by ASTM International for aqueous engine coolant grade glycol, specifically formulated at a nominal 53% concentration by volume. This standard details requirements for ethylene glycol and propylene glycol used in pre-diluted engine coolants, addressing both virgin and recycled sources. By defining physical and chemical properties, purity requirements, and testing methods, it ensures that coolants meet safety, performance, and compatibility parameters necessary for use in automotive and industrial applications.
The standard supports manufacturers, recyclers, and quality assurance professionals in producing and verifying glycol-based engine coolants that comply with Original Equipment Manufacturer (OEM) expectations.
Key Topics
Product Types:
- EG-1 and PG-1: High-purity, likely virgin glycols, suitable for most OEM specifications.
- EG-2 and PG-2: Virgin or redistilled glycols, suitable for many coolant applications.
Applicable Glycol Sources:
- Virgin glycols.
- Recycled vehicle engine coolants.
- Glycols from industrial recycling.
Quality Parameters:
- Clarity and color (Platinum-Cobalt scale).
- Relative density at 20/20°C.
- pH range.
- Minimum glycol content and limits on impurities.
- Freezing point and resistance to corrosion-related contaminants.
Testing Methods:
Includes references to validated ASTM and ISO test methods for determining chemical composition, acidity, metals content, freezing point, density, and more.Safety and Compliance:
- Only SI units are accepted as standard.
- Users are responsible for health, safety, and environmental practices.
- Regulatory compliance regarding packaging, labeling, and transport is required.
Applications
ASTM D7713-18(2023) provides essential specifications for a wide range of automotive and industrial applications:
- OEM Engine Coolants: Supports the formulation of engine coolants that comply with critical OEM requirements for long service life, corrosion resistance, and freeze protection.
- Recycled Coolant Production: Establishes requirements for recycling and redistilling glycol from used vehicle coolants or industrial byproducts, promoting sustainability.
- Quality Assurance: Used as a benchmark by manufacturers and quality-control laboratories to certify glycol blends prior to distribution.
- Regulatory Compliance: Ensures coolant products meet federal, state, and local transportation and labeling rules.
This specification serves coolant manufacturers, recyclers, automotive OEMs, and testing laboratories, facilitating consistent and reliable engine coolant performance across domestic and international markets.
