you seem to have a knack of making other peoples minds up about things dont you!ban-all-sheds said:I may disagree with their pronouncements/policies/attitude/etc., but if a research association says "we have measured the resistance of water in a 15mm plastic pipe and found it to be 115kohms/m", I can't find much basis on which to disagree.
Feel free to add to the list, if you can think of any more reasons, but right now all I can think of is that you disagree because
a) You think they are lying
b) You think they are incompetent
c) You think their instruments were faulty
This is not a case of disputing an opinion or a decision, you are disputing what someone has told you is a fact. You are claiming that the figures published by the ERA are false, in which case you must be able to show why this is, or what evidence you have which leads you to the conclusion that they have published incorrect figures.
I don't subscribe to any of the above things you mention but i base my views on what i consider to be flawed research done under laboratory conditions with fresh water, clean pipes etc and not done in practise using the type of system you'd encounter in your house, lots of people have removed radiators in the past to decorate and the contents are definitely not pure water but contain a sludge (even if inhibitors are used) which is rich in oxides etc and if the test had been conducted properly then the results would be more practical and useful, seems to me that a lot of research is out of touch with really goes on in practise.
Why would they say water can produce a hazard in the first place if it wouldn't? because they could back up the claims using practical means.
when i was at college many years ago we asked the reasons why things were as they were and got good answers that satisfied, what good answer can you come up with why the results you mention have practical meaning in the real world? In other words show me the results that state the composition of the water used and how that relates to water found in practise.
