The tests and measurements should be conducted under the condition of 15 to 35°C of temperature, 25 to 75% of relative humidity and 86 to 106 kpa of
atmospheric pressure unless otherwise specified. If questionable results occur that have been measured in accordance with the above mentioned
conditions, the tests and measurements should be conducted under the condition of 25±2°C of temperature and, 45 to 55% of relative humidity and 86 to
106 kpa of atmospheric pressure.

Item
Measure total resistance between the resistance element and terminals (terminals #1 and #3) with the contact arm
positioned against a stop. The positioning of the contact arm and terminal should be the same for subsequent total
resistance measurements on the same device.
Use the test voltage specified in Table-1 for total resistance measurements. This voltage should be used whenever a
subsequent total resistance measurement is made.
Position the contact arm at the extreme counterclockwise limit of mechanical travel and measure the resistance
between the contact arm and the corresponding end terminal. Then, position the contact arm at the extreme clock-
wise limit of mechanical travel and measure the resistance between the contact arm and the corresponding end ter-
minal. During this test, take suitable precautions to ensure that the rated current of the resistance element is not
exceeded.
Contact resistance variation should be measured with the measuring circuit shown below, or its equivalent. The
operating wiper should be rotated in both directions through 90% of the actual effective-electrical travel for a total of
6 cycles.
The rate of rotation of the operating wiper should be such that the wiper completes 1 count in determining whether or
not a contact resistance variation is observed at least twice in the same location. The test current should follow the
value given in Table-2 unless otherwise limited by the power rating.
The wiper contact point should be preset at about 50% position of effective rotational angle. After that, the poten-
tiometer should be placed in a chamber at 40±2°C and 90 - 95% without loading for 500±12 hours.
The resistance value should be measured after keeping the potentiometer in a room for 5±1/6 hours.
The wiper contact point should be preset at about 50% position of effective rotational angle. After that, the poten-
tiometer should be placed in a chamber at 70±2°C without loading for 500±12 hours. The resistance value should be
measured after keeping the potentiometer in a room for 1.5±1/6 hours.
The wiper contact point should be preset at about 50% position of effective rotational angle. After that, the poten-
tiometer should be placed in a chamber at 40±2°C and 90 - 95% with loading the 1/2 rated voltage between #1 and
#2 terminals, intermittently 1.5 hours ON and 0.5 hours OFF for 1000±12hours.
The resistance value should be measured after keeping the potentiometer in a room for 5±1/6 hours.
The wiper contact point should be preset at about 50% position of effective rotational angle. After that, the poten-
tiometer should be placed in a chamber at 70±2°C (50±2°C for PVZ) with loading the 1/2 rated voltage between #1
and #2 terminals, intermittently 1.5 hours ON and 0.5 hours OFF for 1000±12 hours. The resistance value should be
measured after keeping the potentiometer in a room for 1.5±1/6 hours.
The wiper contact point should be preset at about 50% position of effective rotational angle. After that, the poten-
tiometer should be subjected to Table 3,Table 4 temperature for 5 cycles. The resistance value should be measured
after keeping the potentiometer in a room for 1.5±10 minutes.
