Description / Abstract: The impact-penetration test described is used for the assessment of plastic films and thin sheets under an impact stress applied at right angles to the plane of the film. This part 2 is used if a force-deformation or a force-time diagram, recorded at practically constant velocity of the striker, is necessary for characterization of the impact behaviour. The test method is applicable to films of up to 1 mm thickness and makes it possible to compare impact-penetration forces, biaxial deformabilities and energy-absorption capacities of films.
