TESTS AND REQUIREMENTS
All tests are carried out in accordance with the following
specifications:
Unless otherwise specified the following values apply:
Temperature: 15 °C to 35 °C
EN 60115-1, generic specification (includes tests)
Relative humidity: 45 % to 75 %
EN 140400, sectional specification (includes schedule for
qualification approval)
Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar).
The components are mounted for testing on boards in
accordance with EN 60115-1, 4.31 unless otherwise
specified.
EN 140401-801, detail specification (includes schedule for
conformance inspection)
The components are approved in accordance with the
European CECC-system, where applicable. The following
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 requirements stated in the Test Procedures and
Requirements table are based on the required tests and
permitted limits of EN 140401-801. However, some
additional tests and a number of improvements against
those minimum requirements have been included.
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.
