TESTS AND REQUIREMENTS
Essentially all tests are carried out in accordance with the schedule of
“IEC publication 60 115-8”, category LCT/UCT/56 (rated temperature
range: Lower Category Temperature, Upper Category Temperature;
damp heat, long term, 56 days). The testing also covers the requirements
specified by EIA and EIAJ.
The tests are carried out in accordance with IEC publication 60 068,
“Recommended basic climatic and mechanical robustness testing
procedure for electronic components” and under standard atmospheric
conditions according to
“IEC 60068-1”, subclause 5.3.
Unless otherwise specified the following values apply:
Temperature: 15
°Cto35 °C
Relative humidity: 25% to 75%
Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar).
In Table 4 the tests and requirements are listed with reference to the
relevant clauses of
“IEC publications 60 115-8 and 60068”; a short
description of the test procedure is also given.
In some instances deviations from the IEC recommendations were
necessary for our method of specifying.
All soldering tests are performed with mildly activated flux.
