BS ISO 23598:2021 pdf download – Mechanical joining of sheet materials — Destructive testing of joints — Specimen dimensions and procedure for mechanized peel testing of single joints This document specifies the geometry of test specimens and the testing procedure for mechanized peel testing of single mechanical joints on single-lap test specimens up to a single sheet thickness of 4,5 mm. The term “sheet”, as used in this document, includes extrusions and cast materials. The purpose of the mechanized peel tests is to determine the mechanical characteristics and the failure modes of the joints made with different joining methods. This document does not apply to civil engineering applications such as metal buildings and steel constructions which are covered by other application standards. NOTE For mechanized peel testing of resistance spot, seam and embossed projection welds, see ISO 14270 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

The positional accuracy of the mechanical joints on the test specimen shall be ± 1 mm in every direction. The test specimen for mechanical joints shall be produced as a single joint specimen as shown in Figure 1 b), which is made of two coupons shown in Figure 1 a), and then the mechanized peel test specimen shall...
