Performance requirements of single-ended electric heating tube
1. Heating time
Under the test voltage, the time for the component to rise from the ambient temperature to the test temperature should not exceed 15 minutes.
2. Rated power deviation
Under the condition of sufficient heat generation, the deviation of the rated power of the component should not exceed the range specified below:
For components with rated power less than or equal to 100W: ¡À10%.
For components with a rated power greater than 100W, it is +5% to -10% or 10W, whichever is greater.
3. Leakage current
The cold leakage current and the leakage current after the water pressure and sealing test shall not exceed 0.5mA.
The thermal leakage current at operating temperature should not exceed the calculated value in the formula, but not more than 5mA.
I=1/6 (tT¡Á0.00001)

When multiple components are connected in series to the power supply, the leakage current test should be performed on this group of components as a whole.
4. Insulation resistance
The cold insulation resistance should not be less than 50M¦¸ during the factory inspection
After the sealing test, the insulation resistance after long-term storage or use should not be less than 2000M¦¸.
The thermal insulation resistance at operating temperature should not be lower than the calculated value in the formula, but the value should not be less than 1M¦¸.

5. Insulation compressive strength
The components should be kept under the specified test conditions and test voltage for 1 min without flashover and breakdown.
6. Ability to withstand power-on and power-off
The components should be able to undergo 2000 power-on and power-off tests under the specified test conditions without damage.
7. Overload capacity
The components should withstand 30 cycles of overload test under the specifi |
