Core testing of resistive thermostat

1. Operating temperature/reset temperature test (most critical)

- Cut-off temperature (Cut-off T)

- Reset temperature (Reset T)

- Temperature return difference

- Action accuracy and consistency

2. Static/dynamic resistance test

- Resistance value at room temperature

- Resistance change under high temperature

- Insulation resistance

- On-off resistance (on-resistance, off-insulation)

3. Durability/Lifespan Aging Test

- On-off cycle life

- Temperature shock cycle

- Long-term power-on aging

- Reliability of action frequency

4. Temperature difference and response performance

- Action characteristics under temperature rise rate

- Temperature overshoot

- Response time

- Temperature control accuracy

5. Electrical performance

- Breaking capacity under rated current and rated voltage

- Contact voltage drop

- Voltage resistance (dielectric strength)

- Overload protection performance

6. Mechanical properties

- Impact of installation stress

- Deformation of temperature sensing components

- Fixed structural strength

- Lead wire tensile strength, bending resistance

7. Environmental adaptability test

- Storage at high temperature

- Store at low temperature

- Damp heat cycle

- Temperature cycling
