BSI informed me that this is published and covers, among other stuff, the items below. I guess it would be of interest to some of us. Unfortunately at £330 per copy not I. Why these documents are not publicly available I do not understand. Maybe some one on here has access and can say if there is relevance to us.

Changes in the latest version include:

the addition of requirements for flammable refrigerants,
a new table with requirements for external circuits,
the revision of requirements for openings in fire enclosures,
the revision of requirements for liquid filled components; and
the revision of battery charging requirements.

Hi @jancold , can you check that IEC standard number? EN IEC 62368 is for audio/video and IT equipment (?)

@allyfish yes I cut and pasted it, but I see the header said this:- The updated electronics safety standard is simplifying things.

If it is electronics the rest doesn't seem to make sense?

Two thoughts...

Firstly I agree with @jancold that it is frustrating to have Standards which aren't publicly accessible.
I think it's unacceptable within UK Law for a member of the public to be deemed to be in breach of regulations which they couldn't read in advance without paying money to see if they were relevant!

Secondly, it is theoretically possible for high-powered audio equipment to employ refrigerants...
and perhaps those could be designated 'flammable' 🤔

but if the British Standards Body can't issue announcements with adequate clarity of what they're trying to address,
then they've seriously undermined decades of international recognition!

Save energy... recycle electrons!
