3、recycledpropylene glycol base engine coolant concentrate for use inautomobiles and light-duty vehicles.Committee D15 hasdeveloped this specification using experience,knowledge andresearch from recycling used aqueous base engine coolant andblends of used aqueous base engine coolant and virgin glycol.
4、This standard does not apply to coolant produced from otherglycol sources such as medical waste,distillation bottoms,airplane/airport deicers and polyester production waste.Thisspecification provides a procedure for evaluating engine cool-ant recycling technologies through the recycling of a referen
5、cesynthetic used engine coolant.It also specifies the chemical,physical,and performance requirements for the recycled glycolbase engine coolant concentrate that is produced from thatprocedure.When used at 40 to 70 volume%in water,it willfunction effectively during both winter and summer.Thismaterial
6、 is intended to provide protection against freezing,boiling,and corrosion in automobile or other light-duty servicecooling systems.1.2 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are approximateequivalents and provided for information only.1.3 This
7、 standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1
