TESTS AND REQUIREMENTS

Essentially all tests are carried out in accordance with the schedule of

“IEC publication 60115-1”, category 55/155/56 (rated temperature range

-55 °C to +155 °C; 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 60068-2,

“Recommended basic climatic and mechanical robustness testing

procedure for electronic components” and under standard atmospheric

conditions according to “IEC 60068-1”, subclause 5.3.

In Table 5 the tests and requirements are listed with reference to the relevant

clauses of “IEC publications 60115-1 and 60068-2”; 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.
