TESTS AND REQUIREMENTS

All tests are carried out in accordance with the following

specifications:

EN 60115-1, Generic specification (includes tests)

EN 140 400, Sectional specification (includes schedule

for qualification approval)

EN 140 401-801, Detail specification (includes schedule

for conformance inspection)

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 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

Table 5 Test procedures and requirements

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).

The components are mounted for testing on boards in

accordance with EN 60 115-1, 4.31 unless otherwise

specified.

The requirements stated in Table 5 are based on the

required tests and permitted limits of EN 140 401-801.

However, some additional tests and a number of

improvements against those minimum requirements have

been included.
