PTC Cartridge Heater Reliability Data
| Test Item | Test conditions | Requests |
|---|---|---|
| Environmental variation | Temperature：80℃ (+0/-5) On：3 hours Temperature：-15℃(±2) On: 3 hours With rapid change, change time <3 seconds, for 8 consecutive time. 24 hours at moiststatic room at 40℃, 100% relative humidity. |
PTC Thermistor characteristics curve shall not be changed. No damage to the cables and resin. |
| Vibration Test | Sinusoidal vibration test last on 12 hours, according to 3 axis, composed the following A and B items A) Frequency 10-60Hz, constant deplacement of 1.5mm from peak to peak. B) Frequency 60-200Hz, with accelerator 25g constant to peak. The brushing must occur in continuous way from minimum to maximum value, and vice versa, with a variation of 10Hz second. |
No visible mechanical damage. Function shall not be changed. |
| Control of the insulation layer | Apply voltage 500V, 50Hz to one of the 2 wires and containers for 1 second. | No damage, no discharge. |
