Thanks for bringing this to our attention. Hopefully I'll get a chance to review.

I've not read it in any detail yet but, since this is a new standard, is there some form of commentary providing justification for the various requirements? I expect most things will be obvious in intent but it might save "reverse engineering" the thinking and help contributions be more constructive.

Are you aware of a commercial / industrial equivalent in the offing?

Worth having a look. There is some info on the need and source of certain information.

You will not (as with any standard) get a complete justification for any individual requirement. But there is some commentary on the key lines of thought.

No, and thinking about it, it would be quite complex to provide a standardized approach given the variety of different types of premises and applications (from small "domestic-size" systems up to grid-scale size systems). Such premises have a Fire Safety Risk Assessment, and the guidance (IET Code of Practice for Electrical Energy Storage Systems) points to that as the starting point.

It's not something an electrical designer alone can tackle really?

At first glance there does seem to be some commonality with AS/NZS 5139 (which it also mentions in relation to arc flash). Google did find me a full copy on-line (which I suppose is OK to read for personal/academic research purposes, but probably shouldn't really copy/distribute). It looks quite interesting.
