TESTS AND REQUIREMENTS
All tests are carried out in accordance with the following
specifications:
EN 60115-1, generic specification
EN 60115-8
(successor
of
EN 140400),
sectional
specification
EN 140401-803, detail specification
IEC 60068-2-xx, test methods
The parameters stated in the Test Procedures and
Requirements table are based on the required tests and
permitted limits of EN 140401-803. The table presents only
the most important tests, for the full test schedule refer to
the documents listed above. However, some additional
tests and a number of improvements against those
minimum requirements have been included.
The testing also covers most of the requirements specified
by EIA/ECA-703 and JIS-C-5201-1.
The tests are carried out under standard atmospheric
conditions in accordance with IEC 60068-1, 4.3, whereupon
the following values are applied:
Temperature: 15 °C to 35 °C
Relative humidity: 25 % to 75 %
Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar).
A climatic category LCT / UCT / 56 is applied, defined by the
lower category temperature (LCT), the upper category
temperature (UCT), and the duration of exposure in the
damp heat, steady state test (56 days).
The components are mounted for testing on printed circuit
boards in accordance with EN 60115-8, 2.4.2, unless
otherwise specified.
