DIN EN 15590:2011-11

This document specifies the method used for determining the current rate of aerobic microbial activity of solid recovered fuel (SRF) using the real dynamic respirator index (RDRI). 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 recognized scale of values. This document has been prepared by Technical Committee CEN/TC 343 "Solid recovered fuels", the secretariat of which is held by SFS (Finland). The responsible German committee is Working Committee NA 062-05-83 AA "Sekundärbrennstoffe" ("Recovered fuels") at the Materials Testing Standards Committee (NMP) at DIN.
