2. Low Temperature Test
Put samples in a vessel at the condition of -25
±2˚
C for 120 hours. Then, leave them in a
room temperature for 12hours or more and measure it.

4. Thermal Shock Test
Put samples in a vessel at the condition of -25
˚

˚
C for 30
minutes and this process is repeated 20 cycles. Then, leave them in a room temperature
for 24hours or more and measure it.
