RESISTANCE TO FIRE   
 
20.1 
Electrical components and 
mechanical parts 
 
 
 Apparatus 
design 
Resistance to fire is achieved by a combination of 
engineering design, production methods and by using 
materials with low flammability for internal parts 
 
a) Exemption for components 
contained in an enclosure of material 
FV 0 to IEC 60 707 with openings 
not exceeding 1 mm in width   
 
 
b) Exemption for small components 
as defined in 20.1   
PCB is of flammability class FV 1 or better, and exception 
is made for small components. 
20.1.1 
Electrical components meet the 
requirements of 14.2.5, 14.4, 14.5.3, 
14.6.6 or 20.1.4   
No other electrical components with additional flammability 
requirements. 
20.1.2 
Insulation of internal wiring working 
at voltages > 4 kV or leaving an 
internal fire enclosure, not 
contributing to the spread of fire   
No wires working at voltages > 4kV or leaving an internal 
fire enclosure 
20.1.3 
Material of printed circuit boards on 
which the available power exceeds 
15 W at a voltage between 50 V and 
400 V (peak) a.c. or d.c. meets FV 1 
or better to IEC 60 707, unless used 
in a fire enclosure   
All PCB are of base material with flammability category FV 
1 or better. See List of Critical Components. 
 
 
Material of printed circuit boards on 
which the available power exceeds 
15 W at a voltage exceeding 400 V 
(peak) a.c. or d.c. meets FV 0 to 
IEC 60 707   
< 400V(peak) 
20.1.4 
Components and parts not covered 
by 20.1.1, 20.1.2 and 20.1.3 (other 
than fire enclosures) mounted nearer 
to a potential ignition source than the 
distances in Table 13 comply with 
the relevant flammability category in 
Table 13   
 
 
Components and parts as above but 
shielded from a potential ignition 
source, with the barrier area in 
accordance with Table 13 and fig. 13 
 
20.2 Fire 
enclosure 
 
 
20.2.1 
Potential ignition sources with open 
circuit voltage > 4 kV (peak) a.c. or 
d.c. contained in a fire enclosure to 
FV 1   
No voltages exceeding 4kV, no fire enclosure 
requirement.
