TEST AND REQUIREMENTS

Essentially all tests are carried out according to the schedule of IEC publication 115-8, category

LCT/UCT/56(rated temperature range : Lower Category Temperature, Upper Category Temperature; damp

heat, long term, 56 days). The testing also meets the requirements specified by EIA, EIAJ and JIS.

The tests are carried out in accordance with IEC publication 68, "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 value supplied :

Temperature: 15°C to 35°C.

Relative humidity: 45% to 75%.

Air pressure: 86kPa to 106 kPa (860 mbar to 1060 mbar).

All soldering tests are performed with midly activated flux.
