Anotácia textu normy ASTM D5797-21(2026) :
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.
