Hello John; The front & rear panel is painted metal. The base & sides are a plastic moulding. So yes; the secondary circuit is electrically accessible to the user as the circuit board is mounted to the front panel using metal pillars.
I have not started applying IEC 62368-1 as the testing agency I use has not recommend it. Is IEC 62368-1 the preferred option as opposed to IEC 60065 /60950 with most testing agencies now?

Do you not have those standards (60950-1 and 60065)? You should be looking at IEC 62368-1 as well for a new product development. -- OOO - Own Opinions Only.
