The lower and upper category temperature and the duration of the damp heat, steady state shall be chosen from the following: Lower category temperature: 55 C, 40 C, 25 C and 10 C. Upper category

39、temperature: +85 C, +100 C, +125 C and +155 C. Duration of the damp heat, steady state test: 4, 10, 21 and 56 days. The severities for the cold and dry heat tests are the lower and upper category temperatures respectively. Because of the construction of some surface mount resistor networks these tem

40、peratures will occur between two of the preferred temperatures given in IEC 60068-2-1 and IEC 60068-2-2. In this event, the nearest preferred temperature within the actual temperature range of the surface mount resistor network shall be chosen for this severity. 2.1.2 Temperature coefficients and te
