ISO 14270 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√.
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.
ISO 14270 specifies the object of mechanized peel testing is to determine the peel strength that the test specimen can sustain.
ISO 14270 on destructive testing of welds is useful for:
ISO 14270 guidance provides specimen dimensions and a testing procedure for mechanized peel testing of a single spot, seam, and embossed projection welds.
ISO 14270 helps to provide testing of welds made in high strength materials including ultra-high-strength materials as well as ordinary strength materials.
