Test Results - Door Openings
Door opening simulation were performed at ambient temperatures +40°C and -25°C for single temperature operation just after corresponding stability test. Tests were conducted with empty box and maximum time allowed for recovery was 1 hour.
-
1st. test, 3 minutes' door opening followed by the time required for temperature recovery.
-
2nd. test, 7 minutes' door opening followed by the time required for temperature recovery.
The measured recovery times and air temperature peaks are shown in the table below:

| Air temperature peak | Recovery time after closing doors | Air temperature peak | Recovery time after closing doors | ||
| +40°C | +20°C | +32°C | 3 minutes | +36.1°C | 9 minutes |
| +5°C | +29°C | 15 minutes | +34.6°C | 21 minutes | |
