Insulation Resistance
Lay the resistor on the 90º angle metal V block and apply
rated AC voltage for one minute.
Lay the resistor on the 90º angle metal V block and apply
500Vdc between V block and lead wire for a minute. The
insulation resistance shall be measured while applying the
voltage.

Test Method
Soak in a Isopropyl alcohol for 5 minutes. After drying up
for 5 minutes, stress of 5N is added with absorbent cotton
and it does by five round trips at the rate of one round trip a
second.
Apply 2.5 times rated voltage or max. overload voltage
whichever is lower for 5 seconds and leave in room
temperature for one hour after test.
Tensile:
The body of the resistor is fixed, a static load is added in
the direction of drawing out of the terminal,
and it maintains it for 10 ± 1 seconds.
Tensile strength: 10N
Bend:
Component body shall be fixed so that terminals are
perpendicular to the floor. A static load specified below
shall be applied to the terminal acting in a direction away
from the body. The body of piezoelectric oscillator shall
then be inclined through an angle of 90º in the vertical plane
and then returned to its initial position in 2 or 3 seconds then
the body shall be inclined to the reversed direction through
an angle 90º and then returned to its initial position in 2 or 3
seconds.
Bending strength: 5N
Dip the lead into a solder bath having a temperature of
260ºC ± 5ºC up to 1.5±0.5 mm from the body of the
resistors and hold it for 10± 0.5 seconds and leave in room
temperature for one hour after test.
Dip the lead into a solder bath having a temperature of
245±5ºC up to 1.5±0.5 mm from the body of the resistors
and hold it form 5±0.5 seconds.
The resistor shall be subjected to 5 continuous cycles, each
as show in the table below:

Apply 1.5mm amplitude vibration to three directions
perpendicular to each other 2 hours each,
total 6 hours. Vibrating frequency is
10Hz-55Hz-10Hz cycle in 1 minute sweeping
and repeat cycle.
In the chamber having temp. 40±2ºC and relative humidity
93±3%, apply one percent of the rated power, 1.5 hour ON,
0.5 hour OFF for 1000 hours and leave in room temperature
for one hour after test.
At 70 ± 2ºC, apply rated DC voltage 1.5 hour ON,
0.5 hour OFF for 1000 hours and leave in room temperature
for one hour after test.
