| Test Item | Test Method | Performance Requirements |
| Resistance | Resistance Tolerance Sorter measurement. | Resistance value within nominal resistance and allowable tolerance. |
| Short-time overload | Apply 2.5 times rated voltage for 5 seconds, recover for 1-2h, measure resistance and calculate change rate. | Resistance change: R2%R+0.05 |
| Weldability | Groove welding: dip terminal in (2605) solder for 20.5s, depth 2+0/-0.5mm from body. Observe solder coverage. | More than 90% of the immersed surface is covered. |
| High voltage | Apply specified insulated voltage between pigtails and V-shaped groove for 60 seconds. | Appearance without visible damage, clear mark; no breakdown, arcing. |
| Resistance to Soldering Heat | Measure resistance before test. Dip terminal in 35010 solder for 3.50.5s, depth 2+0/-0.5mm from body. Measure resistance after 1h recovery and calculate change rate. | Resistance change: R1%R+0.05 |
| Rapid temperature change | Cycles: -553 (30min), Room temp (2-3min), 1553 (30min). Perform 5 cycles. Measure resistance after 1-2h recovery and calculate change rate. | Resistance change: R1%R+0.05 |
| Endurance | Place in (703) constant temperature box. Input rated DC voltage, 1.5h on, 0.5h off, cycle 1000h. Measure resistance after 1-4h recovery and calculate change rate. | Resistance change: R5%R+0.1 |
| Outlet strength | Pull: 10N force for 10s. Bending: 5N load, tilt body ~90 in 2-3s, repeat in opposite direction (2 bends total). | Resistance change: R1%R+0.05 |
| Vibration | Distance from body to mounting point 61mm. Frequency 10-500Hz, amplitude 0.75mm or acceleration 98m/s. 2h each on Z, X, Y axes (total 6h). Cycle: 1min (10-55-10Hz). Measure resistance after test and calculate change rate. | 1) Appearance: no mechanical damage. 2) Resistance change: R1%R+0.05 |
| Climate order | Dry heat; circulating wet heat (test Db, 1st cycle); cold; low pressure; circulating wet heat (test Db, remaining cycles); DC load. | Resistance change: R5%R+0.1; Insulation resistance: 100M. |
| Accidental overload | Install sample in wire mesh cylinder 253mm from body. Apply 5, 10, 16 rated power overload for 5min or until open circuit. | Screen cylinder does not fire. |
