    Abstract - (Show below) - (Hide below)

    Applies to high-voltage generators of medical diagnostic X-ray generators and to their subassemblies including the following : - high-voltage generators that are integrated with an X-ray tube assembly; - high-voltage generators of radiotherapy treatment simulators. The object of this standard is to establish particular requirements to ensure safety and to specify methods for demonstrating compliance with those requirements.
