PV 1200: 2004-10

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
