Example:
─ A gear unit is stored exposed outdoors after sea transport, in climatic zone B, while it is kept in seaworthy
packaging
HD
1
= 20 months
(climatic zone: B, transport type: sea transport, transport packaging: seaworthy packaging, packaging
for storage: seaworthy packaging, place of storage: exposed outdoors)
─ After 5 months (LD
1
) , the gear unit is unpacked, covered with a loose tarpaulin, and placed outdoors
besides the mill.
HD
2
= 4 months
(climatic zone: B, transport type: sea transport, transport packaging: seaworthy packaging, packaging
for storage: no packaging, place of storage: covered with loose tarpaulin)
Now, the remaining durability period HD

The remaining durability period of the interior gear-unit preservation after changing the storage type is
3 months.
After one additional month (LD

) , the gear-unit is placed outdoors exposed without packaging. Now, the
remaining durability period HD
3äq
is to be calculated as follows:
Given:
HD
2äq
= 3 months (previously calculated)
LD

= 1 month (actual duration of storage with the previous storage conditions)
HD

= 3 months (maximum durability period with the present storage conditions

The remaining durability period of the interior gear-unit preservation is 1.5 months after combining the
storage types described in the example.
