Test Results – Door Openings

Door opening simulation was performed at ambient temperatures +40°C and -30°C just after corresponding stability test. Tests were conducted with empty box:

  • 1st. test, 5 minutes door opening followed by the time required for temperature recovery.

  • 2nd. test, 10 minutes door opening followed by the time required for temperature recovery.

The maximum time allowed for recovery was 1,5 hours.

The measured recovery times and air temperature peaks are shown in the table below:
