This International Standard specifies specimen dimensions and a testing procedure for mechanized peel testing of single spot, seam and embossed 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 7Öt (where t is the sheet thickness in mm). For welds of diameter between 5Öt and 7Öt, it is possible to underestimate the value of peel strength when using the recommended test specimen dimensions because the test specimen width is designed for welds of diameter of 5Öt or less. The object of mechanized peel testing is to determine the peel strength that the test specimen can sustain.
