Annex C: Characterization of the Bulk Sample “Capacitors from Ballasts in Fluorescent tube lamps” In the table below, quantities and weights of the analysed capacitors from fl uorescent tube lamps or ballasts for fl uorescent tubes, respectively, are compiled: Table 13 Sampling of capacitors from lamps; quantities and weights (campaign June – July 2007) Company Quantity apacitors Weight Capacitors [ kg ] Average Weight [ kg ] Weight Lamps [ kg ] Share Capacitors in Lamps [ % ] Company 1 55 6.5 0.118 291 2.2 Company 2 318 38.0 0.119 880 4.3 Company 3 134 16.1 0.120 713 2.2 Total 507 60.6 0.120 1884 3.2 Compared to a previous study by the Cantonal Laboratory Aargau (Kantonales Labor Aargau), the average weight of the capacitors (0.120 g) is lower by about 65 %. Such a difference is probably due to a higher share of more recent and, thus, capacitors lighter in weight (see Fig. 5 and Fig. 6). From the 507 collected capacitors, 239 (47 %) were individually characterized with the name of the manufacturer, model / type, production date, weight and specifi c declarations. But considering the state of the capacitors (damages, painting), not all of them could be categorised unambiguously. On the whole, 124 of the 507 examined capacitors (24 %) were designated as PCB-free. The average service life of capacitors from ballasts varies between 20 and 30 years (Kuhn and Arnet 2000). It may therefore be assumed that a signifi cant share of PCB-containing capacitors is still in use.
