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 following table contains the applicable tests selected

from 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, 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).

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-xx test

methods. A short description of the test procedure is also

given.
