Please pay attention to the following issues when testing thermal switch samples:
1.The internal temperature of testing equipment should be even and consistent. The temperature difference between any two points should be less than 1℃;
2.The temperature rising speed should be under control. The speed can be fast before the temperature reaches the 10℃ lower than bottom limit of rated temperature tolerance value. After that, the speed has to be at or lower than 1℃ per 2 minutes. And the ambient temperature rises to the rated range slowly.
3.When installing thermal switches to the testing equipment, the body of thermal switch should contact the testing facility tightly and effectively. The circuit connection should be workable. If there is a temperature sensing head or thermocouple inside of the equipment, it should be mounted on the effective position.
4.The test equipment should be calibrated on time and work properly.
