TEST AND REQUIREMENTS
All tests are carried out in accordance with the following
specifications:
IEC 60115-1, generic specification (includes tests)
EN 140400, sectional specification (includes schedule for
qualification approval)
EN 140401-801, detail specification (includes schedule for
conformance inspection)
The testing also covers most of the requirements specified
by EIA/IS-703 and JIS-C-5202. The tests are carried out
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).
The components are mounted for testing on boards in
accordance with EN 60115-1, 4.31 unless otherwise
specified. The parameters stated in the Test Procedures and
Requirements table are based on the required tests and
permitted limits of EN 140401-801.
