EN 15590:2011 (E) 4 Introduction This document specifies the method used for the determining the current rate of aerobic microbial activity of SRF using the real dynamic respirator index. The current rate of aerobic microbial activity measures the biological stability under the actual chemical and physical properties of the SRF. The biological stability determines the extent to which readily biodegradable organic matter has decomposed. Therefore, the RDRI identifies the actual point reached in the decomposition process and represents a gradation on a recognised scale of values. SIST EN 15590:2011



EN 15590:2011 (E) 5 1 Scope This European Standard specifies a method to determine the current rate of aerobic microbial activity of a solid recovered fuel. The methods indirectly estimate the potentiality of odours production, vectors attraction etc. The current rate of biodegradation can be expressed in milligrams O2 kg-1 dm h-1. WARNING — SRF can contain potentially pathogenic organisms. Take appropriate precautions when handling them and those whose properties are unknown.

dry matter in kg 5 Principle The method for determining the current rate of aerobic microbial activity specified in this European Standard is based on measuring the oxygen uptake rate by micro-organisms to biodegrade easily degradable organic matter of the sample itself under defined continuous airflow and adiabatic conditions. The test involves keeping the sample under observation in the respirometer (dynamic test system) for 1 day to 4 days according to the duration of the lag phase (if present), taking the index value at hourly intervals (RDRIh) (Clause 8). Moreover, if at the end of the fourth day, the RDRI trend is constant or growing, the respirometric test is prolonged with the acquisition of at least others 24 values (RDRI h) (see Figure A.1). 6 Apparatus The apparatus consists of: 6.1 Dessicator. 6.2 Continuous flow aerobic respirometer, composed of (see Figure 1):  hermetically sealed adiabatic reactor with the minimum operating volume expressed in litres, equal to or les
