Standard Specification for Fuel Methanol (M70-M85) for Automotive Spark-Ignition Engines
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers the methanol fuel blend, M70-M85, for use in ground vehicles that run on automotive spark-ignition engines. Fuels are grouped into three vapor pressure classes (Classes 1, 2, and 3) on the basis of seasonal and geographical volatility. The fuel blends shall undergo chemical analysis for methanol, higher alcohols, hydrocarbon/aliphatic ether, acidity as acetic acid, solvent washed and unwashed gum content, total chlorine as chloride, lead, phosphorus, water, sulfur, and inorganic chloride. The product's appearance shall be clear and bright, visibly free of suspended or precipitated contaminants.
Scope
1.1 This specification covers a fuel blend, nominally 70 to 85 volume % methanol and 30 to 14 volume % hydrocarbons for use in ground vehicles with automotive spark-ignition engines. Appendix X1 discusses the significance of the properties specified. Appendix X2 presents the current status in the development of a luminosity test procedure for M70-M85.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 The following precautionary caveat pertains only to the test method portions–Annex A1, Annex A2, Annex A3, and Appendix X2 of this specification.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.
