only one or several aspects of the product are evaluated. As in the
United States, medical devices such as the United States, medical X-ray
diagnostic apparatus to comply with US law and the relevant radiation
and beam Flow accuracy, but because UL only X-ray as a grading product, so only
to evaluate its mechanical properties, electrical performance and other
non-radiative performance of these aspects. 4.
