BS 7375 - Why is this a separate Standard?

Hi all;

Long time no speak - I hope everyone is well.

I have just read BS 7375 as part of my CPD and other then some commentary on the uses and restrictions of PME and the ideas behind a Pilot Cable and Earth/PE monitoring and a couple of nice Appendices demonstrating typically site layouts - what is the point of this standard, why couldn't not of been absorbed into Chapter 7? Is there some "politicking" here (for a lack of suitable phrase) between the IET and BS and how the both co-exist?

My best.

I suspect it's historical - the two having grown up separately and never quite got harmonized (I've a feeling there are still technical differences between BS 7671's version of RLV and BS 7375's - especially around the need for automatic disconnection on Earth faults). Others here will know better - one occasional poster was I think very much involved with BS 7375 a few years ago.

Possibly similar situation with 721 and BS EN 1648 and perhaps 710 and HTM documents.
