(Specification)Standard Specification for Methyl Tertiary-Butyl Ether (MTBE) for Downstream Blending for Use in Automotive Spark-Ignition Engine Fuel
Standard Specification for Methyl Tertiary-Butyl Ether (MTBE) for Downstream Blending for Use in Automotive Spark-Ignition Engine Fuel
ABSTRACT
This specification covers requirements for fuel grade methyl tertiary-butyl ether utilized in commerce, terminal blending, or downstream blending with fuels for spark-ignition engines. The following test methods shall be conducted to meet the specified requirements: appearance; sulfur; solvent-washed gum content; MTBE mass percentage; methanol mass percentage; API gravity; density; copper strip corrosion; water content; vapor pressure; and color.
SCOPE
1.1 This specification covers requirements for fuel grade methyl tertiary-butyl ether utilized in commerce, terminal blending, or downstream blending with fuels for spark-ignition engines. Other MTBE grades may be available for blending that are not covered by this specification.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
