TESTS AND REQUIREMENTS
All executed tests are carried out in accordance with the The testing also covers most of the requirements specified following specifications: by EIA/IS-703 and JIS-C-5201-1. EN 60115-1, generic specification The tests are carried out under standard atmospheric EN 60115-8, sectional specification conditions in accordance with IEC 60068-1, 4.3, whereupon the following values are applied: EN 140401-802, detail specification Temperature: 15 °C to 35 °C IEC 60068-2-xx, test methods Relative humidity: 25 % to 75 % The parameters stated in the Test Procedures and Requirements table are based on the required tests and Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar). permitted limits of EN 140401-802. The table presents only A climatic category LCT / UCT / 56 is applied, defined by the the most important tests, for the full test schedule refer to lower category temperature (LCT), the upper category the documents listed above. However, some additional temperature (UCT), and the duration of exposure in the tests and a number of improvements against those damp heat, steady state test (56 days). The components are minimum requirements have been included. mounted for testing on boards in accordance with EN 60115-8, 2.4.2 unless otherwise specified.
