Hi Doug, You are right that test with 1mm wire does not apply if no speaker terminals.
There are 3 requirements - protection against electric shock, clause 5, test figer shall not touch bare live parts. - protection against fire - openings shall comply with fire enclosure requirements (e.g. less than 5mm for side openings, max 3mm for bottom openings) - protection against foreign object - Annex P. I hope.this helps.

I'm examining audio equipment that has small ventilation holes above the AC Mains Inlet. Hastily my mind jumped to the rigid wire test (V.1.6) for stripped wire terminals intended for wiring speakers to audio power amps. But this particular unit is not a power amp and it does not have that sort of wiring terminal. My angst is about the mains voltage immediately behind the ventilation holes. Section, 5.3.2.4 says to check each wire terminal opening as well as any other openings within 25 mm. And I this case the 1mm x 100mm wire easily reaches inside. In my original thinking, I saw this as a potential end-user hazard and thought this wire probe might be a good idea to use in this case. So, my client balked, and I can definitely see his point. These vent holes are not for speaker terminals, and also not for stripped wire by the end user. As written in the standard, this is not a great fit for that purpose. So what section of the standard, if any, applies here? Thanks! ~Doug Douglas E Powell Vertex Compliance Consulting Laporte, Colorado, USA ________________________________ This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
