Ethanol as a blending component for petrol. Determination of total dry residue (involatile material). Gravimetric method1 Scope This European Standard specifies a procedure for the determination of dry residue in ethanol by gravimetric (desiccation) method in the range (10 to 25) mg 100 ml. NOTE In an interlaboratory study [2] the method described has been tested at levels down to 3,5 mg 100 ml, but the precision appeared to be insufficient at such low levels. WARNING Use of this document may involve hazardous equipment, materials and operations. This method does not
