IEC 60806:2022 is applicable to X-RAY SOURCE ASSEMBLIES and X-RAY TUBE ASSEMBLIES.
This document specifies a method for the determination of the greatest geometrically symmetrical RADIATION FIELD at a specified distance from the FOCAL SPOT for which the percentage AIR KERMA RATE along the major axes of the RADIATION FIELD does not fall below a permitted value.
In case multiple FOCAL SPOTS are not super-imposed, each FOCAL SPOT has its own REFERENCE AXIS. Then the maximum RADIATION FIELD can be given for each FOCAL SPOT separately.
IEC 60806:2022 cancels and replaces the first edition published in 1984. This edition constitutes a technical revision.
This edition includes the following significant technical change with respect to the previous edition:
a) addition of solid state detectors as they have become more common since the first edition of 1984.
