High-

Temperature

Operation

=50℃,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 60 068-2-2Bp.

When experiment

finished, the EPD

must meet

electrical and

optical

performance

standards.

Low-

Temperature

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 60 068-2-2Ab.

When experiment

finished, the EPD

must meet

electrical and

optical

performance

standards.

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 60 068-2-2Bp.

When experiment

finished, the EPD

must meet

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 60 068-2-2Ab

When experiment

finished, the EPD

must meet

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

60 068-2-3CA.

When experiment

finished, the EPD

must meet

electrical and

optical

performance

standards.
