Special conditions
Ensure that additional measures for
components are taken, which are used
in an environment involving:
– dust, caustic vapors or gases
– ionizing radiation
Reduced buffer time at high storage temperature!
Ensure that the storage of devices with a real time clock at high temperatures
leads to a reduced buffer time for the real time clock.
