Re: X-ray based NDT Test Equip. Mfger. seeking CE Mark - Must X-Ray Source be include
Have all applicable EC Directives, Regulations, Decisions etc. been identified? Typically, the governing directive would have the definitions and requirements to answer such questions, right in the first few articles.
In general I tend to agree that the CE marking relates to product use together with any specified accessories (= elements required for allowing it to achieve its designated goal).
