ISO 14270:2016

OVERVIEW

ISO 14270:2016 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 7vt (where t is the sheet thickness in mm).

For welds of diameter between 5vt and 7vt, the peel strength values obtained may be lower than expected when using the recommended test specimen dimensions because the test specimen width is designed for welds of diameter of 5vt or less.

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