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.
