Hang on ... in 2001 edition, Table 41C (48A) is NOT an equivalent of what we have now in Table 41.1.


My apologies - I do not have the  copies to compare here, and the notes implied it was the same.  (and given even the 1977  version is 100 CHF it will be some time before we do have all possible standards here, an up to date copy of a few of them is quite enough...) However, it is interesting to know where the figures come from, as there are clearly some assumptions hidden . I will edit my post to delete the implication that it is the same.

There appear to be assumptions, some of which I may humbly not agree with.


IMO these values need to be revisited and discussed further.
