rise to the test temperature should not be greater than 15min.

2, see the rated power deviation, in the full heat conditions, the rated power of the

heating tube deviation should not exceed the specified range.

3, see insulation resistance, electric tube factory inspection when the cold insulation

resistance should be not less than 50MΩ.

4, to see the insulation pressure strength, electric tube should be in the specified test

conditions and test voltage to maintain 1min, without flashover and breakdown phenomenon.
