| Surge Impact Performance | Test as per Figure 3; repeated switching for 100 cycles (2s ON, 2s OFF) should not result in an open circuit. |
| No. | Test Item | Test Method | Performance Requirement |
|---|---|---|---|
| 1 | Resistance | Measured by resistance error sorter. | Resistance value within nominal resistance and allowable deviation. |
| 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 ends in solder pot (2605) for 20.5s, depth 2+0/-0.5mm from body. Observe solder coverage. | Over 90% surface coverage in circumferential direction of the dipped part. |
| 4 | Voltage Proof | Place resistor in metal "V" groove, apply specified insulation voltage between leads and groove for 60s. | No visible damage, clear marking; no breakdown or arcing. |
| 5 | Resistance to Soldering Heat | Measure resistance before test, dip lead ends in solder pot (35010) for 3.50.5s, depth 2+0/-0.5mm from body. Recover 1h, measure resistance, calculate change rate. | Resistance Change: R(1%R+0.05) |
| 6 | Rapid Temperature Change | Cycle: Low temp (-553) (30min) -> Room temp (2-3min) -> High temp (1553) (30min) -> Room temp (2-3min). Repeat 5 cycles. Recover 1-2h, measure resistance, calculate change rate. | Resistance Change: R(1%R+0.05) |
| 7 | Endurance | Place in constant temperature oven (703), apply rated DC voltage (1.5h ON, 0.5h OFF) for 1000h. Recover 1-4h, measure resistance, calculate change rate. | Resistance Change: R(5%R+0.1) |
| 8 | Lead Strength | Tensile: 10N for 10s. Bending: Apply 5N load, tilt body ~90 (2-3s), recover, bend 90 in opposite direction (2 bends total). | Resistance Change: R(1%R+0.05) |
| 9 | Vibration | Resistor body 61mm from mounting point. Frequency 10-500Hz, amplitude 0.75mm or acceleration 98m/s (whichever is smaller). Directions Z, X, Y axes for 2h each (total 6h). Cycle 1min (10-55-10Hz). Measure resistance, calculate change rate. | 1) Appearance: No mechanical damage. 2) Resistance Change: R(1%R+0.05) |
| 10 | Climatic Sequence | Dry heat -> Cyclic damp heat (Db, 1st cycle) -> Cold -> Low pressure -> Cyclic damp heat (Db, remaining cycles) -> DC load. | Resistance Change: R(5%R+0.1). Insulation Resistance: 100M. |
| 11 | Accidental Overload | Install sample in single-layer wire mesh cylinder (253mm from body). Apply 5, 10, 16 times rated power overload for 5min or until open circuit. | Wire mesh cylinder does not ignite. |
