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.
