This International Standard specifies specimen dimensions and a testing procedure for shear testing of spot, seam and embossed projection welds, in overlapping sheets, in any metallic material of thickness 0,5 mm to 10 mm, where the welds have a maximum diameter of 7√t (where t is the sheet thickness in mm). With welds of diameter ＞ 5√t and ≤ 7√t, the value of shear strength can be underestimated when using the recommended test specimen dimensions.
The object of shear testing is to determine the shear force that the test specimen can sustain.
