ASTM D7901-14b

ASTM D7901-14b - 15.10.2014

1. Scope

1.1 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.

Note 1: The generation and dissipation of static electricity can create problems in the handling of DME. For more information on the subject, see Guide D4865.

1.2 The values stated in SI units are to be regarded as standard. Units 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.
