TESTS AND REQUIREMENTS
Essentially all tests are carried out in accordance with the
following specifications:
EN 60115-1, generic specification (includes tests)
EN 140100, sectional specification (includes schedule for
qualification approval)
CECC 40101-806, detail specification (includes schedule
for conformance inspection)
The following table contains the applicable tests selected
from the documents listed above.
The tests are carried out in accordance with IEC 60068-xx
test method and under standard atmospheric conditions in
accordance with IEC 60068-1, 5.3. Climatic category
LCT/UCT/56 (rated temperature range: Lower Category
Temperature, Upper Category Temperature; damp heat,
long term, 56 days) is valid.
Unless otherwise specified the following values apply:
Temperature: 15 °C to 35 °C
Relative humidity: 45 % to 75 %
Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar).
For testing the components are mounted on a test board in
accordance with IEC 60115-1, 4.31 unless otherwise
specified.
In the Test Procedures and Requirements table only the
tests and requirements are listed with reference to the
relevant clauses of IEC 60115-1 and IEC 60068-2 test
methods. A short description of the test procedure is also
given.
