This Particular Standard is confined to those devices which are MEDICAL ELECTRICAL EQUIPMENT and in which
- the storage capacitor is in the high-voltage circuit and has a specified capacitance not exceeding 2F,
- the INITIAL X-RAY TUBE VOLTAGE is between 40 kV and 150 kV,
- an overcurrent protection, if provided, would not require a rating exceeding that which corresponds to an apparent power of 3kVA,
- LOADING of the X-RAY TUBE is controlled in the high-voltage circuit.
This Particular Standard does not exclude CAPACITOR DISCHARGE X-RAY GENERATORS that are capable of operation in CONTINUOUS MODE for DIRECT RADIOSCOPY or INDIRECT RADIOSCOPY. However, for this mode of operation the device will have to comply with the relevant requirements for dianostic HIGH-VOLTAGE GENERATORS and diagnostic X-RAY EQUIPMENT (see Sub-clause 1.3.102).
