This International Standard specifies the geometry of the test specimens and the method for the cross-tension 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 International Standard, includes extrusions and cast materials. The purpose of the cross-tension test is to determine the mechanical characteristics and the failure types of the joints made with different joining methods. This International Standard does not apply to civil engineering applications such as metal building and steel construction which are covered by other applicable standards.
