ASTM issues specification for DME as fuel

ASTM International has issued a standard specification (ASTM D7901-14) for Dimethyl Ether for fuel purposes. This specification covers dimethyl ether (DME) for use as a fuel in engines specifically designed or modified for DME and for blending with liquefied petroleum gas (LPG).

This specification is for use by manufacturers of dimethyl ether, by engine developers of purpose-built engines, in contracts for the purchase of DME for fuel purposes, and for the guidance of consumers of this type of fuel.

The standard, cautioned ASTM, does not purport to address all of the safety concerns, if any, associated with its use. The generation and dissipation of static electricity can create problems in the handling of DME. More information on this subject is contained in Guide D4865.
