|---|---|---|---|
| 1 | Resistance | Measured by resistance error sorter. | Resistance value within nominal resistance and allowable tolerance range. |
| 2 | Short-time Overload | Apply 2.5 times rated voltage for 5S, recover 1-2h, measure resistance, calculate change rate. | Resistance change: R(2%R+0.05) |
| 3 | Solderability | Dip lead into solder pot (2605) for 20.5S at depth 2+0/-0.5mm from body, observe coverage. | Over 90% surface coverage in circumferential direction of dipped part. |
| 4 | Withstand Voltage | Place resistor in metal 'V' groove, apply specified insulation voltage between leads and groove for 60S. | No visible damage, clear marking; no breakdown, arcing. |
| 5 | Withstand Soldering Heat | Measure resistance before test, dip lead into solder pot (35010) for 3.50.5S at depth 2+0/-0.5mm from body, recover 1h, measure resistance, calculate change rate. | Resistance change: R(1%R+0.05) |
