TESTS AND REQUIREMENTS

Essentially all tests are carried out in accordance with the

following specifications:

EN 140000/IEC 60115-1, Generic specification (includes

tests)

EN 140100/IEC 60115-2, Sectional specification (includes

schedule for qualification approval)

CECC 40101-806, Detail specification (includes schedule for

conformance inspection)

Most of the components are approved in accordance with the

European CECC-system, where applicable. The Test

Procedures 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 60 068 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; a short

description of the test procedure is also given.
