BS EN ISO 14270:2016

This standard BS EN ISO 14270:2016 Resistance welding. Destructive testing of welds. Specimen dimensions and procedure for mechanized peel testing resistance spot, seam and embossed projection welds is classified in these ICS categories:

• 25.160.40 Welded joints and welds

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 7√ t (where t is the sheet thickness in mm).

For welds of diameter between 5√ t and 7√ t, 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 5√ t or less.

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