20 RESISTANCE TO FIRE

20.1 Electrical components and mechanical parts

a) Exemption for components contained in an

enclosure of material V-0 to IEC 60707 with

openings not exceeding 1 mm in width

Not applied.

b) Exemption for small components as defined in

20.1

All capacitors smaller than

1750mm

, IC, transistors and

photo couplers are mounted on

a PCB with V-0 (or better).

20.1.1 Electrical components meet the requirements of

Clause 14 or 20.1.4

See sub clause 14 and 20.1.4.

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

Internal PVC wiring working at

voltage less then 4 kV.

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

V-1 or better to IEC60707, unless used in a fire

enclosure

See below.

Material of printed circuit boards on which the

available power exceeds 15 W at a voltage >400 V

(peak) a.c. or d.c. meets V-0 to IEC 60707

PCB with V-0 or better material

used for power supply.

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 21 comply with the relevant

flammability category in Table 21

Plastic enclosure material is

rated with flammability class V-

Components and parts as above but shielded from

a potential ignition source, with the barrier area in

accordance with Table 21 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 V-1

Less than 4 kV.
