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 40 101-806, Detail specification (includes schedule

for conformance inspection)

Most of the components are approved in accordance with

the European CECC-system, where applicable. Table 5

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 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

1 060 mbar).

For testing the components are mounted on a test board in

accordance with IEC 60115-1, 4.31 unless otherwise

specified.

In Table 5 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.
