BS EN ISO 16526-1:2020

Non-destructive testing. Measurement and evaluation of the X-ray tube voltage. Voltage divider method | Status: Under review, Current

1 Scope This part of ISO 16526 specifies a method for the direct and absolute measurement of the average high voltage of constant potential (DC) X-ray systems on the secondary side of the high voltage generator. The intention is to check the correspondence with the indicated high voltage value on the control unit of the X-ray system. This method is applied to assure a reproducible operation of X-ray systems because the voltage influences particularly the penetration of materials and the contrast of X-ray images and also the requirements concerning the radiation protection.
