12.1 Servicing explosion-pro -
tected devices
If a part of the device on which the explosion
protection is based needs to be serviced, the
device must not be put back into operation
until a qualified inspector has assessed it ac -
cording to explosion protection require-
ments, has issued an inspection certificate,
or given the device a mark of conformity. In-
spection by a qualified inspector is not re -
quired if the manufacturer performed a rou-
tine test on the device before putting it back
into operation. Document the passing of the
routine test by attaching a mark of conformi-
ty to the device.
Replace explosion-protected components on-
ly with original, routine-tested components
by the manufacturer.
Devices that have already been used outside
hazardous areas and are intended for future
use inside hazardous areas must comply
with the safety requirements placed on ser-
viced devices. Before being operated inside
hazardous areas, test the devices according
to the specifications for servicing explo
-
sion-protected devices.
EN 60079-19 applies to servicing explo -
sion-protected devices.
