Approval sheet  
TEST AND REQUIREMENTS(JIS C 5201-1 : 1998)  
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.
