What is the intuitive meaning of the strict norm and co-norm

The characterization of t-norm is that
WEAK(x,y) <= T(x,y) <= min{x,y} where WEAK(x,y) = min{x,y} if max{x,y}
=1 and 0 otherwise
Similarly a t-conorm satisfies
max{x,y} <= S(x,y) <= STRONG{x,y} where STRONG(x,y) = max{x,y} if
min{x,y} =0 and 1 otherwise
Are there any significant examples where we can attach a meaningful role
for WEAK and/or STRONG?
