ENVIRONMENTAL CHARACTERISTICS (1) Insulation Resistance IEC 60115-1, 4.6: in V-block for 60 seconds, the test resistance should be high than 1,000 M Ohm. (2) Dielectric Withstanding Voltage IEC 60115-1 4.7: flashover. (3) Place resistors in V-block for 60 Seconds, no breakdown or Temperature Coefficient Test IEC 60115-1, 4.8: Test of resistors at room temperature and 60°C or 100°C on request above room temperature. Then measure the resistance. The Temperature Coefficient is calculated by the following equation and its value should be within the range requested. R  R0 1 Re sistor Temperature Coefficient    10 6 R0 t  t0 R = Resistance value under the testing temperature R0 = Resistance value at the room temperature t = the 2nd testing temperature t0 = Room temperature (4) Short Time Overload Test IEC60115-1 4.13: At 10 times rated voltage or 2 times the maximum working voltage whichever is lower for 5 seconds, the resistor should be free from defects. The change of the resistance value should be within ±(0.25%+0.05 Ω) for precision type and ±(1.0%+0.05 Ω) for commercial type as compared with the value before the test. (5) Solderability IEC 60115-1, 4.17: 235±5°C for 3±0.5 Seconds, there are at least 95% solder coverage on the termination. (6) Resistance to soldering heat: IEC 60115-1, 4.18: 260±3°C for 10±1 Seconds, immersed to a point 3±0.5mm from the body. The change of the resistance value should be within ±(0.25%+0.05 Ω) for precision type and ±(1.0%+0.05 Ω) for commercial type as compared with the value before the test. www.thunder-resistor.com sales@thunder-resistor.com page 9 of 10 (7) Damp Heat Steady State IEC 60115-1, 4.24: 40±2°C, 90-95% RH for 56 days, loaded with 0.1 times RCWV or the maximum working voltage whichever is lower.
