The following standards apply to E-100 fuel ethanol
(The identification test methods are incorporated herein by reference):
Specifications for E-100 Fuel Ethanol | ||
| Specification | Value | Test Method |
| Ethanol | 92 vol. % (min.) | ASTM D 3545-90a |
| Other alcohols and ethers | 2 mass % (max.) | ASTM D 4815-89 |
| Hydrocarbons, gasoline or diesel fuel derived | 5 mass % (max.) | ASTM D 4815-89, and then subtract concentration of alcohols, ethers and water from 100 to obtain percent hydrocarbons |
| Acidity as acetic acid | 0.007 mass % (max.) | ASTM D 1613-85 |
| Total chlorine as chloride | 0.0004 mass % (max.) | ASTM D 3120-87 modified for the determination of organic chlorides, and ASTM D 2988-86 |
| Copper | 0.07 mg/1 (max.) | ASTM D 1688-90 as modified in ASTM D 4806-88 |
| Lead | 2 mg/1 (max.)b | ASTM D 3229-88 |
| Phosphorus | 0.2 mg/1 (max.)c | ASTM D 3231-89 |
| Sulfur | 0.002 mass % (max.) | ASTM D 2622-87 |
| Gum, heptane washed | 5 mg/1 (max.) | ASTM D 381-86 |
| Total particulates | 5 mg/1 (max.) | ASTM D 2276-89, modified to replace cellulose acetate filter with a 0.8 micron pore size membrane filter |
| Water | 1.25 mass % (max.) | ASTM E 203-75 |
| Appearance | Free of turbidity, suspended matter and sediment | Visually determined at 25°C by Proc. A of ASTM D 4176-86 |
| __________ | ||
a The denaturant must meet the ASTM D 4806-88 specification for denatured fuel ethanol, except the denaturant cannot be rubber hydrocarbon solvent. The final blend specifications for E-100 take precedence over the ASTM D 4806-88 specifications.
b No added lead.
c No added phosphorus.
