Overview

This pre-standard specifies a method for the determination of bridging properties of solid recovered fuels using standard measuring equipment. The method is applicable to all particulate recovered fuels that either have been reduced in size (such as cut tyres, plastics, cardboards) or physically in a particulate form (such as pellets, granules or fluff obtained from waste materials or dry sewage sludge). Bridging or arching is a complex parameter describing the situation when particles form a stable bridge over an opening that can be several times the length of the single particles. Bridging is dependent on several influencing factors, for instance the conveying or transport system, particle size and shape, moisture content, bulk density, bed depth. Bridging is not an absolute value and therefore there is a need for standardising the conditions for the determination of bridging tendency in order to gain comparative measuring results. CEN/TS 15406 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") of NMP.
