EN 15402:2011 (E) 4 Introduction The volatile matter is determined as the loss in mass less that due to moisture, when solid recovered fuel is heated out of contact with air under standardised conditions. The test is empirical and, in order to ensure reproducible results, it is essential that the rate of heating, the final temperature and the overall duration of the test are carefully controlled. It is also essential to exclude air from the solid recovered fuel during heating to prevent oxidation. The fit of the crucible lid is therefore critical. The moisture content of the sample is determined at the same time as the volatile matter so that the appropriate correction can be made. Mineral matter associated with the sample can also lose mass under the conditions of the test, the magnitude of the loss being dependent on both the nature and the quantity of the minerals present. This European Standard is primarily geared toward laboratories, producers, suppliers and purchasers of solid recovered fuels, but is also useful for the authorities and inspection organizations. The method specified in this European Standard is based on EN 15148 as well as ISO 562. SIST EN 15402:2011



EN 15402:2011 (E) 5 1 Scope This European Standard specifies the requirements and a method for the determination of volatile matter of solid recovered fuels. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 15357:2011, Solid recovered fuels — Terminology, definitions and descriptions EN 15414-3, Solid recovered fuels — Determination of moisture content using the oven dry method — Part 3: Moisture in general analysis sample EN 15442, Solid recovered fuels — Methods for sampling EN 15443, Solid recovered fuels — Methods for the preparation of the laboratory sample 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 15357:2011 apply. 4 Principle A test portion of the general analysis sample is heated out of contact with ambient air at (900 ± 10) °C for about 7 min. The percentage of volatile matter is calculated from the loss in mass of the test portion after deducting the loss in mass due to moisture. 5 Apparatus 5.1 Furnace The furnace shall be heated electrically and capable of maintaining a zone with uniform temperature of (900 ± 10) °C. It may be of the stop-ended type or fitted at the back with a flue with a diameter of about 25 mm and a length of about 150 mm (see Figure 1). NOTE 1 It is important for furnaces with flues that the furnace door seals well. The flue should not reach far out of the oven and should be fitted with a butterfly valve to restrict airflow through the furnace. The heat capacity of the furnace shall be such that, with an initial temperature of (900 ± 10) °C, the temperature is regained within about 4 min after insertion of a cold stand and its crucibles. The temperature shall be measured with a thermocouple, as specified in 5.2. NOTE 2 Observing the temperature is very important in order to compensate for inherent deviations of the temperature measurement and lack of uniformity regarding the temperature distribution. Usually the furnace will be designed specifically either for multiple determinations using a number of crucibles in one stand or for receiving one crucible and its stand. In the first case, the zone of uniform temperature shall be at least 160 mm × 100 mm; in the latter case, a zone of diameter about 40 mm is sufficient. SIST EN 15402:2011
