This Nordtest method specifies procedures for weld examination in thin materials by manually operated ultrasonics. The method is limited to ordinary carbon steel, aluminium alloys and austenitic steel with commonly accepted qualities for conventional ultrasonic testing. The thickness range covered is from 7 mm down to 3 mm, i.e. below the ranges covered by ordinary procedures for ultrasonic weld examination which often apply a lower limit of around 8 mm.


Nordtest is a trademark of Nordic cooperation in conformity assessment. The emphasis of Nordtest is to develop, promote and innovate Nordic test methods and pre-normative activity. Nordtest endeavours to remove technical barriers to trade and promotes the concept: “Approved once, accepted everywhere”.
