5.4.2.1.2 Pull-through resistance under shear loadsSample strips are mechanically fixed to a wooden batten or a metal profile with one fixing.On specimens of the cladding and substructure at least 5 shear tests each according to Figure8 shall be carried out.When testing, the edge distances a min and b min (accord. to figure 8) shall be conform tothe smallest edge distances intended to be used for the cladding kit.On the test specimens with the lowest ultimate loads the number of tests shall besupplemented so that for a statistical evaluation at least 7 test results are available.For fixings of parts of the exterior wall cladding which have nearly the same stiffness, the testsshall be performed according to Figure 8.c).If a part is almost rigid in comparison with the other, the tests shall be performed according toFigure 8.d).If the relative stiffnesses are between those requiring tests to Figure 8.c) and 4.d), then bothtests shall be carried out.The speed rate shall be adjusted to 5 mm/min.a) view b) viewF Q : shear forcea min : smallest intended edgedistance of the claddingb min : smallest intended edgedistance of the subframes 1 : thickness of the claddings 2 : thickness of thesubframec) section, case 1 d) section, case 2Figure 8 - Examples of shear load testETAG 03442
