It's probably a good idea to wipe older NR/SR cranks down and look for discolored spots in that long shallow milled groove in the outer surface. When I've seen Campy arms break in that area there is always discoloring on the outside and through the cross section, maybe indicating that the crack grew slowly and dirt infiltrated it.
