New edition of IEC 60364-7-701 (Special locations containg a bath or shower)

-2400-
Just posting in case it is of interest...

IEC have recently published IEC 60364-7-701:2019. This is the standard that Section 701 of BS7671 is based on, so the changes might or might not roll through in a future update of '7671.

The Abstract is free to view (along with a longer preview) on the IEC website at https://webstore.iec.ch/publication/28906 and is pasted below:

Abstract



IEC 60364-7-701:2019 applies to electrical installations in indoor or outdoor locations where a bath tub and/or a shower is intended to be permanently placed in a specific location.
The extent of the location containing a bath tub and/or a shower is limited by:

– the lowest finished floor level;

– a horizontal plane 3 m above the lowest finished floor level;

– a vertical circumscribing virtual surface at a distance of 4 m from the fixed water outlet for the bath tub or shower; and

– the volume within the walls, floor and ceiling that border the location containing a bath or shower, measured to a depth of 6 cm.

The requirements of this document also apply to fixed electrical installations in mobile applications, for example caravans, mobile homes, shower containers. This document does not apply to emergency facilities, for example emergency showers used in industrial areas or laboratories.

This third edition cancels and replaces the second edition published in 2006. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous edition:

– the scope gives precisions relevant to the application of this document;

– the description of zones is improved;

– relevant terms are defined.

    Earlier this year I worked in a domestic wet room that measures 5.000 metres x 6.000 metres with welded vinyl flooring turned up the walls all around as skirting, some wet rooms are huge.


    On my theme of odd coincidences, a few days after I did that job I was looking at this forum and thought I must have been working close to where Dave Z lives as I read one of his posts and had a look at his website then had a look at Google maps. I had been to hire a ladder to get up to an extractor fan outlet and the hire shop was behind his house, when we were getting the ladder out of the rack I was literally at the bottom of his garden and had drove past his front door four times that day without realising it.


    Life is full of coincidences.
