Full Description

This International Standard specifies specimen dimensions and a testing procedure for mechanised peel testing of single spot, seam and projection welds, in overlapping sheets, in any metallic material of thickness 0,5 mm to 3 mm, where the welds have a maximum diameter of 7t (where t is the sheet thickness in mm). With welds of diameter 5t and 7t, it is possible to underestimate the value of peel force when using the recommended test specimen dimensions.

The object of mechanized peel testing is to determine the peel force that the test specimen can sustain.
