3.4.1 General Conditions
The severity of the requirements is in conformity with: IEC 721-3-2
classes 2K4/2B2/2C2/2S2/2M2. and ETS 300 019-1-2 Class 2.3
"PUBLIC transportation".
These requirements are valid for equipped cabinets (excluding
batteries). The values in these conditions are valid for a maximum
transport time of 3 months. The time is measured from the moment the
packages are leaving the shipping store, and includes storing in
connection with the transport.
Note: These requirements restrict flight transportation to aircrafts
with pressure cabins. As modern aircrafts have pressure
cabins, these limitations are expected to be only formal.
Note: The severity levels are chosen with equipped cabinets in
mind. Therefore, transport of equipment outside the cabinets
can result in extremes. These extremes shall be handled by
its own packing.
3.4.2 Climatic Conditions
During transportation the equipment could be exposed to extremes in
temperature and humidity. The equipment must be packaged. The
equipment shall be operational after being subjected to the ambient
temperature and humidity stated hereafter.
The severity of these requirements are in conformity with: IEC 721-3-2
class 2K4. and ETS 300 019-1-2 Class 2.3.
