Thermostat: Testing and Inspection
INSPECTION
Replace the thermostat if the valve does not close completely at an ambient temperature or if the following test shows unsatisfactory results.

Inspection method
Immerse the thermostat and a thermometer in water. Raise water temperature gradually, and measure the temperature and valve lift when the valve
begins to open and when the valve is fully opened. During the test, agitate the water for even temperature distribution. The measurement should
conform to the specification.
Starting temperature to open: 80 - 84°C (176 - 183°F)
Fully opens: 95°C (203°F)
NOTE:
^
Leave the thermostat in the boiling water for more than five minutes before measuring the valve lift.
^
Hold the thermostat with a wire or the like to avoid contacting with container bottom.
