Measurements of floor insulation resistance in medical rooms
The electrodes shall consist of a plate having a surface of 20 cm
2
, weight equal to
approx. 1 Kg (10N), and a humid absorbing paper ( or humid thin cotton cloth) with
the same surface placed between the metal plate and the floor.
The insulation resistance is represented, both for the measurements indicated in "a"
and for the measurements indicated in "b", by the average of 5 or more tests
Test a):
Connect one test lead of
the instrument to the
equalising potential node
and the other to one of
the electrodes placed on
the floor at a distance
higher than one meter
away from earthed
objects.
Test b):
Connect the instrument
test leads to the
electrodes placed on the
floor at a reciprocal
distance of one meter.
