DIN Standards Committee Materials Testing

Overview

This document has been prepared by Technical Committee CEN/TC 19 "Gaseous and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin", the secretariat of which is held by NEN (Netherlands). The responsible German Committee is NA 062-06-81 AA, Mirror Committee of CEN/TC 19 "Gaseous and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin" of the Petroleum, Fuels, Lubricants and Related Products Standardization Committee (FAM) of NMP. This European Standard specifies requirements and test methods for delivered and marketed ethanol to be used as an extender for automotive fuel for petrol engine vehicles in accordance with the requirements of EN 228. This document gives all relevant characteristics, requirements and test methods for (bio)ethanol, which are known at this time to be necessary to define the product to be used up to a maximum 10 % (V/V) blending component for automotive petrol fuel. These requirements need to be restudied if the percentage or use is expanded beyond 10 % (V/V) volume. The major updates of this version concern the inclusion of newly developed test methods for determination of appearance of the automotive petrol fuel, of the content of oxygenates, water, involatile material, sulfate, inorganic chloride, copper and phosphorus. These test methods were under development at the time of publication of the first version. In addition, some units were converted to the mass percentage rate (m/m). A test method has also been developed on the basis of a DIN test method in order to adequately limit the acidic character and the alkaline components of the product, which cannot be sufficiently determined via pHe. The former version gave all relevant characteristics, requirements and test methods for (bio)ethanol, which were known at that time to be necessary to define the product to be used up to a maximum 5 % (V/V) blending component for automotive petrol fuel. With the current document, the percentage of use is expanded to allow use at percentages up to 10 % (V/V) and the requirements are updated accordingly. Now that a test method is available, a sulfate limit has also been set.
