Is that pipe likely, inclined, tending, disposed, apt, predisposed, prone or given to come into contact with a live wire?
If not then it is not an exposed-conductive-part. Why do you completely refuse to recognise that?

It is not impossible, maybe a low risk of it happening but not impossible
I do recognise that as a definition of pipework come into a romm through the wall. floor or ceiling., I also recognise that floating pipe work can aquire potentials that are different to the potential ( most often Earth potential ) on other pipe work.
Bernard and PBC:
You are, of course, entirely free to earth all the pipes in your house and then hope the more likely danger never happens - especially to another member of your family.
Don't wear your seat belts either; in an accident you may all be thrown clear

The risk of being involved in a accident where the seat belt is necesary is very small. Yet it is a legal requirement to wear a seat belt when travelling in a car.
Sometimes when extracting people from a crashed vehicle the seat belt delays the extraction.
NOTE unless there is immediate danger to life from fire or further impacts to the vehicle casualties should not be extracted until trained emergency crews are on scene to deal with the extraction.

Far, far less small (20/3000?) than being electrocuted even though it is mandatory.
Instead of scraping them of the windscreen (If they did not fly through it) and removing the steering wheel from the chest, you mean?
Instead of leaving them on the windscreen?
Although, what has that got to do with anything?
I don't think there is any hope.
It does not have to be merely possible.
It has to be liable.
Liable means likely, inclined, tending, disposed, apt, predisposed, prone or given to.
So I repeat, and you can have another chance to answer each of these.

But is it liable to acquire such potentials?
You are playing with words.
Is the electrical bonding of the two taps of a wash basin liable to increase the risk of serious injury. ?
The argument that bonding them would make one of them "earthed" and hence increase the risk of a serious electrical shock has a big flaw
Consider the cold tap. It is not bonded to the hot tap. It is being claimed that bonding the cold tap to the hot tap will make the cold tap more dangerous if touched by someone already in contact with a Live conductor or faulty appliance. If the bonding the taps together will make the cold tap more dangerous than when it was not bonded then ask yourself what would happen if the person touches the hot tap instead of the cold tap.
Yes - If you mean compared to one being earthed and the other isolated.
It would make both of them earthed.
Yes.
I think you are still referring to the hot tap being earthed by its connection to immersion/boiler.
If so, then the hazard exists only on the hot tap but it would on both taps in your world.
Insert a plastic flexible connector on the hot if you are concerned or, better still, at the immersion/boiler.
However, you do not seem to be concerned because you want the hazard on both taps and everything else.
Or perhaps they're wrong now. Changes in the wiring regs. don't always make things stricter as is often assumed - Removal of supplementary bonding requirements, increasing the current rating of cables, relaxing the standards for maximum voltage drop, etc.
Fair enough, but that will involve a lot of such strategically placed isolating sections in many cases - A plastic coupling on the inlet and outlet of every radiator to ensure that an earthed appliance pushed back onto the radiator won't extend earth potential around the system, similar couplings where a pipe goes from one room to another so that an accidental earth on the pipe in one room isn't extended into the next room, and so on.
It may be. In some cases in may be just as likely (or unlikely) to happen as the casing of a class I appliance coming into contact with a live wire from inside.
If it's metallic and exposed to touch, then by definition it's an exposed conductive part whether or not it's likely/possible/probable/liable to come into contact with anything else.
Indeed, a length of floating pipework running parallel for some distance to a cable could well sit at a significant potential due to capacitive coupling.
Oh. Come on Bernard.
You were the one who mentioned a hot tap earthed by the immersion or boiler and the cold not.
Obviously both are likely to be connected, aren't they?
If isolating them was chosen to make them safer, then the same would be done to both.

I don't think they are.
No - I am using words according to what they mean, not pretending that they are either not in the definition of an e-c-p or that in that definition they actually mean something different to normal.
Are the taps likely to come into contact with a live wire? Yes or no?
Are the taps inclined to come into contact with live wires? Yes or no?
Do the taps tend to come into contact with live wires? Yes or no?
Are the taps disposed to come into contact with a live wire? Yes or no?
Are the taps apt to come into contact with a live wire? Yes or no?
Are the taps predisposed to come into contact with a live wire? Yes or no?
Are the taps prone to coming into contact with live wires? Yes or no?
Are the taps given to coming into contact with live wires? Yes or no?
Well "may be" simply isn't good enough.
It either is or is not liable to introduce a potential.
It either is or is not an e-c-p.
