JBD...
The term comes from Bussman...
And their little known calculations in Uglies...
This has been discussed up thread.
Times, terms ...
They do change.
As an identifiable calculation...
It's been out there for quite some time.
Must you stand as King Knute damning the tides?
It's not as if I or any poster here came up with the notation.
Instead, it comes from the premier manufacturer of fuses.
I understand that as of 2011 the Code expects this calculation to be done across the board.
BTW, if you were a real historian of scientific/technical notation then you'd know of the CONSTANT shift of terms of art. If you were to read Newton - you'd choke on his writing. The Physics is the same -- but NOT the notation.
Against the influence of Uglies and Bussman...
Your purity of notation must be for nought.
INRE your assumption that I was wildly off base: I think I've answered that.
The purpose of ECN is to expand knowledge...
NOT to get into personal disputes and putdowns.
That kASC is, in your view, not a correct/traditional notation does not mean that the term is not in use -- constantly, if Bussman is to be followed.

From here on, such calculations are destined to be ever more common. I don't particularly care WHAT the notation is.
But that kASC/kSCA point to the SAME metric works for me.
