TESTS PROCEDURES AND REQUIREMENTS
All tests are carried out in accordance with the following
specifications:
• IEC 60115-1, generic specification (includes tests)
The test and requirements table contains only the most
important tests. For the full test schedule refer to the
documents listed above.
The tests are carried out in accordance with IEC 60068-2-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, steady state, test duration: 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 performing some of the tests, the components are
mounted on a test board in accordance with IEC 60115-1,
4.31.
In 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-xx test methods.
A short description of the test procedure is also given.
