One cycle (see Figure 1) lasts for 720 min (12 h) and comprises the following temperature and humidity profiles:
60 min heating phase to +80 °C and 80% rel. humidity,
240 min holding time at +80 °C and 80% rel. humidity,
120 min cooling phase to -40 °C, when freezing point is reached: approx. 30% rel.
humidity, the air humidity remains unregulated as of T < 0 °C
(depending on the system, humidity regulation can also
be  suspended as of T < 10 °C),
240 min holding time at -40 °C, air humidity remains uncontrolled,
60 min heating phase to +23 °C, rel. humidity is regulated to 30% as of T = 0°C Array
