Destructive tests on welds in metallic materials. Method for taking samples for delta ferrite measurement1 Scope This European Standard specifies the determination of the delta ferrite content of welds, of surfacings with austenitic weld metal, welding being carried out on welding procedure tests and production coupon test plates using any fusion welding process that is suitable for austenitic materials, with or without filler metal including welds made on components. It is intended that the ferrite number be used exclusively for stating the delta
