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.
