ASTM D7388-18

Standard Specification for Engine Coolant Grade 1,3-Propanediol (PDO)

ABSTRACT
This specification covers engine coolant grade 1,3-propanediol (PDO). Engine coolant grade 1,3-propanediol shall conform to the chemical and physical property requirements specified. Density or relative density, color of clear liquids, pH, trace chloride ion, ion chromatography analysis, digital density meter, ethylene glycols and propylene glycols analyses, and inductively couple plasma-atomic emission spectroscopy tests shall be performed.
SCOPE
1.1 This specification covers engine coolant grade 1,3-propanediol (PDO).  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.

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.
