| Title | Plastics - Determination of puncture impact behaviour of rigid plastics - Instrumented impact testing |
| Scope | This international standard specifies a test method for the determination of puncture impact properties of rigid plastics, in the form of flat specimens, using instruments for measuring force and deflection. It is applicable if a force-deflection or force-time diagram, recorded at nominally constant striker velocity, is necessary for detailed characterization of the impact behaviour. |
| Comment | Recently, the trend has been to test plastics, reinforced and unreinforced, in the falling weight or falling dart test using either Part 1 (un-instrumented) or Part 2 (instrumented) of ISO 6603 [28]. For composites, when tested on the 40 mm diameter support, the failure can be limited and influenced by the proximity of the edge of the support ring. The 100 mm diameter support added during the latest revision in 1997 is much less likely to influence the failure. This difference in failure behaviour also applies to unreinforced plastics. The instrumented tests allow load, displacement and energy values to be obtained at different points throughout the test, such as at the peak, at any particular event and at test completion (ie test specimen puncture). |
