There are many standards for medical/dental applications, but most use one or more sections of UL/EN 60601-1.

There are typically two (2) options: • The transformer manufacturer submits the transformer to the applicable safety agencies for component approval(s), or, • The end product manufacturer submits the transformer for investigation along with the end product. In this case, the transformer manufacturer provides the end product manufacturer with the requisite transformer documentation needed by the investigating agency.
