Figure 5: Solvent curve FDL 115
The diagram shows the highest permissible solvent quantity G total [g] in the steam room in correspond-
ence to the drying temperature. This is based on the calculation acc. to EN 1539:2009 considering the
unit specific data, an assumed molecular weight of the solvent of 100g/Mol, and a lower explosion limit of
40g/m 3 at 20 °C / 68 °F and at 760 Torr (1013 hPa) (assumptions for unknown solvents acc. to EN
1539:2009).
