ASTM D7388-08

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 the standard. The values given in parentheses are for information only.
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.
