This document specifies the performance requirements of instruments as used in the NON -INVASIVE MEASUREMENT of X- RAY TUBE VOLTAGE up to 1 50 kV and the relevant compliance tests. This document also describes the method for CALIBRATION and gives guidance for estimating the uncertainty in measurements performed under conditions different from those during CALIBRATION .
Applications for such measurement are found in diagnostic RADIOLOGY including mammography,COMPUTED TOMOGRAPHY (CT), dental radiology and RADIOSCOPY . This document is not concerned with the safety aspect of such instruments. The requirements for electrical safety applying to them are contained in IEC 61 01 0-1 .
