If the ISO standard (which will be agreed by a vote among nations) is to be accepted (not just ‘passed’) it has to be relevant. The key missing ingredients so far are a) the discussion of what is done during a test has not been extended to the concepts that under lie it, - we have just been rehashing the old WBT pioneered 25 years ago. And b) it has not been externally reviewed by a competent authority. Obviously both these issues have been brought to the attention of the relevant parties. The world of ISO standards is not like the garage mechanic stove inventers writing their own ad hoc tests of what they think should happen or be looked at. Do in a large amount of work does not always overcome fundamental obstacles. > 3.

How is this: I give you 5 litres of water in a pot and ask you to bring it to a boil. You put it in a fire and bring it to what we agree is ‘a boil’ by which time 100 cc has evaporated. I ask you how many litres of water you have just boiled. What is your answer? That is an example of a conceptual difference. The WBT says you boiled 4.9. An engineering will say you boiled 5.0. Is this cognitive dissonance or conceptual error? Regards Crispin
