The product is placed in a chamber of -40±2℃,
for 96 hours. Measurement is done after
recovery of 4~24 hours.
The specimens are placed in a chamber and the
temp is then lowered to -20±2℃ for one hour.
The temp will raised to +80±2℃ for one hour.
This constitues one cycle. Ten cycles of such
testing shall be completed. Measurement is made
after recovery for 4~24 hours from the
completion of testing.
