TESTS AND REQUIREMENTS

Essentially all tests are carried out in accordance to the schedule of IEC publications 60115-1, category 65/275/56 (rated

temperature range - 65 °C to + 275 °C; damp heat, long term, 56 days and along the lines of IEC publications 60068-2);

“Recommended basic climatic and mechanical robustness testing procedure for electronic components” and under standard

atmosphere conditions according to IEC 60068-1 subclause 5.3, unless otherwise specified. In some instances deviations from

IEC applications were necessary for our method specified.
