Siemens FD20 Guideline

Open plastic fire (TF4)
4.3 Combustible material
The zone factor is determined on the basis of the area of the room (not to be
confused with the monitoring area per detector) and the room height (Figure 5).
This zone factor can then be used to determine the number of mats required for
the test as shown in Table 4.
