Abstract

1.1 This part of ISO 6603 specifies a method for the determination of the multiaxial impact behaviour of rigid plastics in the form of flat test specimens, such as discs and squares, moulded directly or cut from sheets. This test is used for the characterization of plastic sheeting or mouldings under the impact of a striker applied at a right angle to the plane of the sheet. Different test parameters are specified depending on the geometry of the striker. 1.2 ISO 6603-1 1) can be used if it is sufficient to characterize the impact behaviour of plastics by an impact-failure energy. This part of ISO 6603 is for use if a force-deformation or force-time diagram recorded at practically constant striker velocity is necessary for characterization of the impact behaviour. This applies if - measured quantities derivable only from this diagram are required; - only a small number of test specimens is available. 1.3 The test method is applicable to test specimens with a thickness between 1 mm and 4 mm. NOTE 1 For thicknesses less than 1 mm, ISO 7765-2 should be used. Thicknesses greater than 4 mm may be tested if the equipment is suitable, but the test then falls outside the scope of this part of ISO 6603. 1.4 The test results are comparable only if the conditions of the preparation of the specimens, their dimensions and surfaces as well as the testing conditions are the same. In particular, results determined on test specimens of different thicknesses cannot be compared with one another. Comprehensive evaluation of the reaction to impact stress requires that determinations be made as a function of deformation rate and temperature for different materials variables, such as crystallinity and moisture content, The impact behaviour of finished products cannot be predicted directly from this test, but specimens may be taken from finished products for tests by this method. 1) ISO 6603-1:1985, Plastics - Determination of multiaxial impact behaviour of rigid plastics - Part 1: Falling dart method.
