din 1615:1984
hi everyone,
can anyone tell me if the din standard -
din 1615:1984fff"> - welded circular unalloyed steel tubes not subject to special requirements
has been superceeded by an en standard, and if so what is its new name?
it seems like an old enough standard, and the fact that most of the din and bs standards are now falling under the en standards, i thought there may have been some thing new.
i have trawled the information superhighway interweb thingy looking for it, but to no avail.  
if anyone can help, it would be much appreciated.

it appears to still be valid.
