Ground leaking resistance
from the work piece attach-
ment point
The ground leaking resistance of the attachment
point of every work piece may be 1 megohm at
most (measuring voltage must be 500 V or
1000 V). The design of the work piece holder
must ensure that the work pieces remain
grounded during coating.

Measures to take if the work
pieces are insufficiently
grounded
If sufficient work piece grounding in accordance
with section 6 cannot be ensured, appropriate
equipment, e.g., ionizers, must be used to dis-
charge electric charges on the work piece. Such
equipment must not exceed the permitted dis-
charge energy of the spraying systems with
which it is used. In terms of permitted discharge
energy, this equipment must be put through the
same inspections as the powder spraying sys-
tems used with it. The discharge equipment
must be interlocked with the spraying system
such that the high voltage is switched off and
that coating cannot take place if the discharge
equipment malfunctions.
