What to put in 'Distribution reference' on forms?

No greater than IPX2 or IPX4.
In fact IPXXB is 0.5mm smaller than IPX2.
I just didn’t realise the XXB/D related to internal access to live parts.

I wouldn't agree that it's no greater. See this for example: IET Forums - Cable Trunking IP4X or IPXXD (BS 7671 Regulation 521.10.1) - https://---------------/forums/forum/messageview.cfm?catid=205&threadid=104323

(Just realised I got the numbers in the wrong place, IP2X and IP4X.)
This is the info I have:
IP2X = will not allow a sphere with 12.5mm diameter to enter,
IPXXB = will not allow a British Standard jointed Finger to come into contact with live parts. British Standard jointed finger is 12mm diameter and 80mm long.
IP4X will not allow 1mm diameter wire to enter,
IPXXD will allow a 1mm diameter wire to enter, but must not come into contact with live parts to a depth of 100mm.

Yes indeed, but a large object could enter so long as it doesn't come into contact with live parts. That is what I was pointing out about large gaps being possible with IPXXB/IPXXD.
