Scope: This standard specifies the bridge method and voltage divider method for testing the interelectrode capacitance of electron tubes. The bridge method is suitable for testing the capacitance between electrodes of the electron tube in the range of 0.000 1 pF to 4 000 pF. The measurement method of arbitration is the bridge method. This standard is applicable to the test of interelectrode capacitance of space charge control tubes, cathode ray tubes, gas-filled tubes, vacuum photoelectric tubes and microwave tubes.
