ISO/TC 44/SC 6/WG 4 - Joint ISO/TC 44/SC 6 - ISO/TC 2 WG: Mechanical joining of sheet materials

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

This document gives recommendations for test specimens and procedures for performing constant load amplitude fatigue tests on single- and multi-joint sheet specimens in the thickness range from 0,5 mm to 6 mm at room temperature and a relative humidity of max. 80 %. NOTE The thickness range for advanced high strength steels (AHSS) and ultra high strength steels (UHSS) is generally below 3,0 mm. Greater thicknesses apply for aluminium alloys, for example. This document covers: — testing of joints to evaluate materials; — evaluation of the influence of joint type and joint size on the test results; — evaluation of the influence of load type and load mode on the test results; — testing of component-like specimens to evaluate their structural performance. Depending on the specimen used, it is possible from the results to evaluate the fatigue behaviour of joints under shear-, peel-, normal-tension and combinations of loads and that of the tested specimen. The results of fatigue testing obtained with component like specimens are suitable for deriving criteria for the selection of materials and thickness combinations for structures and components subjected to cyclic loading. This statement is especially relevant for results obtained with specimens with boundary conditions, i.e. a local stiffness, similar to that of the structure in question. The results of fatigue testing are suitable for direct application to a design only when the loading conditions in service and the stiffness of the design in the joint area are similar. This document does not apply to civil engineering applications such as metal building and steel construction which are covered by other applicable standards.

ISO 16237:2015 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. ISO 16237:2015 does not apply to civil engineering applications such as metal building and steel construction which are covered by other applicable standards.

ISO 13469:2014 specifies the requirements for the testing procedures for interference-fit/form-fit blind rivet joints and lock bolt joints made of metallicand non-metallic materials. The tests required for a particular joint depend upon the performance requirements of the component/assembly and shall be established before any testing is undertaken. The term sheet as used in ISO 13469:2014 includes extrusions, cast material, plastics, and fibre-reinforced plastics, e. g. carbon and glass fibre-reinforced plastics. ISO 13469:2014 does not apply to civil engineering applications such as metal building and steel construction which are covered by other applicable International Standards.

ISO 12996:2013 specifies the geometry of the test specimens and the procedure for the tensile shear testing of single mechanical joints on single and multilayer specimens up to a single sheet thickness of 4,5 mm. The term sheet, as used in ISO 12996:2013, includes extrusions and cast materials. The purpose of the tensile shear test is to determine the mechanical characteristics and failure modes of the joints made with the different methods. ISO 12996:2013 does not apply to civil engineering applications such as metal building and steel construction which are covered by other applicable standards.
