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 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.
Abstract
Overview
EN ISO 14270:2016 (ISO 14270:2016) specifies specimen dimensions and a mechanized peel testing procedure for destructive testing of resistance welds - specifically spot, seam and embossed projection welds. The standard applies to overlapping metallic sheets with thicknesses from 0.5 mm to 3.0 mm and to welds with a maximum diameter of 7√t (t = sheet thickness in mm). The primary objective is to determine the mechanized peel strength (MPS) - the maximum peel force a specimen can sustain.
Key topics and requirements
- Scope & limits
- Applicable sheet thickness: 0.5 mm ≤ t ≤ 3.0 mm.
- Maximum weld diameter: 7√t; note that for welds between 5√t and 7√t, results may be lower than expected using the recommended specimen width.
- Specimen dimensions and tolerances
- Table values for common thicknesses: flange length a = 50 mm, specimen width b = 50 mm, free length ≥ 160 mm, length between clamps 105 mm, edge distance 25 mm (for 0.5
