HOUSTON (ICIS)--A set of specification standards for a glycerine grade to be used in engine coolants is nearing release by ASTM International, market sources said on Thursday.

The first specification for ASTM-engine-coolant-grade glycerine (D7640) has been approved, according to glycerine market participants.

The engine coolant specification will be released for industry-wide publication in August, according to glycerine sources.

Several ASTM engine coolant glycerine specification sets are in various stages of development, with expectations that light and heavy-duty vehicle coolant systems using glycerine will enter markets by 2012.

Refined glycerine of 99.5% purity will be one of the blendstocks for several coolant systems, sources said.

ASTM-approved specifications are widely sought for new products coming into the US automotive industry because the approval process includes a series of testing parameters that often take several years to complete.

US refined glycerine producers include Procter & Gamble, Vantage Oleochemical, Twin Rivers Technology, Dial and Cargill.

ASTM is also known as the American Society for Testing and Materials.
