3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1 Filament characteristics
Relationship between X-ray tube filament current and filament voltage.
3.2 Maximum operating tube voltage
Since the half-wave rectifier circuit, X-ray tube anode rated current between the anode and cathode of the maximum allowed forward anode voltage
Peak.
3.3 Maximum peak reverse voltage
X-ray tube anode current provisions, the maximum allowed withstand peak reverse voltage between the anode and the cathode.
3.4 Overvoltage
In the anode current and test time prescribed between the X-ray tube anode and cathode by adding a predetermined overvoltage coefficient determined
Peak voltage.
3.5 Filament emission characteristics
Under the given conditions of tube voltage, anode current and filament current (voltage) relationship between the X-ray tube.
3.6 Anode current stability
X-ray tube under specified operating conditions and within the stipulated time, the amount of the maximum anode current variation of the rated current value of the ratio of the anode.
