Hmm. Interesting English usage statement.
If something fills an opening, the opening no longer exists. So, how do you
know how to apply the requirement?

Subject: [PSES] 62368-1 Openings in a fire enclosure
Hi Experts,
I have a EN 62368-1 question regarding openings in a fire enclosure…
6.4.8.2.2 Requirements for a fire enclosure
Material for components that fill an opening in a fire enclosure or that is
intended to be
mounted in such opening shall:
* comply with the flammability requirements of the relevant IEC component
standard; or
* be made of V-1 class material; or
* with Clause S.1.
For PS2 and PS3 circuits I have been told by a test house that connectors in
fire enclosure openings only have to be V-1 class material if they are close to
a potential ignition source (PIS).
My interpretation is that a fire enclosure is a fire enclosure, regardless of
where, within a fire enclosure a fire may start and so anything filling an
opening must be V-1.
I am interested to know how do other engineers interpret this clause.
Many thanks,
