40.1.3
Each sample is to be placed at the bottom of an
empty, isolated, conductive metal tub of a
convenient size. The tub is to be equipped such
that it can be filled from beneath at a rate of no
greater than 5 inches (127 mm) of water per hour.
The tub is to be connected to earth ground
through a noninductive 500-ohm resistor. As the
tub is filled, the leakage current is to be continually
measured and a trace of the current flow as a
function of time is to be obtained. The water flow is
to be stopped when the leakage current reaches 6
milliamperes or the immersion detection functions,
whichever occurs first. One minute after the
immersion detection has tripped and without
changing any of the test conditions, a user-
resettable IDCI is to be reset and the current
value and tripping time measurements are to be
repeated. The results are acceptable if in each
immersion the immersion detection trips at a
current
N/A
Less than 6 milliamperes or
N/A
Greater than 6 milliamperes in a period of time to
comply with the time and current relationship
specified in 40.1.1. The period of time is to be
measured from the moment the current flow
exceeds 6 milliamperes to the moment the current
ceases to flow. When the immersion detection
trips, the flow of current to ground is to cease
N/A
40.1.4
The isolated tub described in 40.1.3 is to be filled
with 12 inches (305 mm) of water.
Three samples are to be dropped into the water
such that different surfaces of the samples strike
the water first. The leakage current is to be
continuously measured and a trace of the current
flow as a function of time is to be obtained
N/A
40.1.5
The tests described in 40.1.2 40.1.4 are to be
conducted two separate times using water with a
resistivity of 200 ohm-cm and 20,000 ohm-cm as
described in 40.1.7.
N/A
40.1.6
A typical test arrangement for the test described in
40.1.3 is shown in Figure 40.1. In the
arrangement, the pump is connected to a source
of supply of variable voltage so that the water flow
rate may be regulated. The tubing that connects
the holding tank to the pump and the pump to the
conductive tank is nonmetallic flexible tubing (such
as aquarium air hose) and is of such length that it
extends to the bottom of the conductive tub so that
the water fills the tub from below
N/A
40.1.7
The water resistivities specified in 40.1.5 are to be
obtained by the addition of sodium chloride
(common table salt) to distilled water or tap water.
The water temperature is to be 20 40°C (68
104°F)
