1.1 This test method covers the determination of the ethanol content of hydrocarbon blends containing greater than 20% ethanol. This method is applicable to denatured fuel ethanol, ethanol fuel blends, and mid-level ethanol blends.
1.1.1 Ethanol is determined from 20 mass% to 100 mass% and methanol is determined from 0.01 mass% to 0.6 mass%. Equations used to convert these individual alcohols from mass% to volume% are provided.
Note 1–Fuels containing less than 20% ethanol may be quantified using Test Method D5599, and less than 12% ethanol may be quantified using Test Method D4815.
