Applies to those components of X-ray equipment which influence the image quality and patient dose of diagnostic X-ray systems using radiographic and radioscopic imaging systems.Defines:- the parameters which describe the performance of X-ray equipment with regard to imaging properties and patient dose;- methods of testing wether measured quantities related to those parameters comply with the specific tolerances.The aim is to verify compliance of the installation with specifications relating to the image quality and patient dose, and to detect malfunctions that are not in agreement with those specifications.
