TEST CONDITION METHOD REMARK
1
High-Temperatu
re Operation
T =40℃,
RH=35% for 240
hrs
When the experimental cycle finished, the EPD samples
will be taken out from the high
temperature environmental chamber and set aside for a few
minutes. As EPDs return to room temperature, testers will
observe the appearance, and test electrical and optical
performance based on standard # IEC 60068-2-2Bp.
When experiment
finished, the EPD
must meet electrical
and optical
performance
standards.
2
Low-Temperatu
re Operation
T = 0℃ for 240
hrs
When the experimental cycle finished, the EPD samples
will be taken out from the low
temperature environmental chamber and set aside for a few
minutes. As EPDs return room temperature, testers will
observe the appearance, and test electrical and optical
performance based on standard # IEC 60068-2-2Ab.
When experiment
finished, the EPD
must meet electrical
and optical
performance
standards.

High-Temperatu
re Storage
T = +60℃,
RH=35%
for 240 hrs
Test in white
pattern
When the experimental cycle finished, the EPD samples
will be taken out from the high
temperature environmental chamber and set aside for a few
minutes. As EPDs return to room temperature, testers will
observe the appearance, and test electrical and optical
performance based on standard # IEC 60068-2-2Bp.
When experiment
finished, the EPD
must meet electrical
and optical
performance
standards.

Low-Temperatu
re Storage
T = -25℃
for 240 hrs
Test in white
pattern
When the experimental cycle finished, the EPD samples
will be taken out from the low
temperature environmental chamber and set aside for a few
minutes. As EPDs return to room temperature, testers will
observe the appearance, and test electrical and optical
performance based on standard # IEC 60068-2-2Ab.
When experiment
finished, the EPD
must meet electrical
and optical
performance
standards.

Operation
T=+40℃,
RH=80%
for 240 hrs
When the experimental cycle finished, the EPD samples
will be taken out from the environmental chamber and set
aside for a few minutes. As EPDs return to room
temperature, testers will observe the appearance, and test
electrical and optical performance based on standard # IEC
60068-2-3CA.
When experiment
finished, the EPD
must meet electrical
and optical
performance
standards.
