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)

EN 140101-806 (successor of CECC 40101-806), detail

specification (includes schedule for conformance inspection)

The Test and Requirements table contains only the most

important tests. For the full test schedule refer to the

documents listed above. The testing also covers most of the

requirements specified by EIA/IS-703 and JIS-C-5202.

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.
