scope:

This document 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. The test method is applicable to specimens with a thickness between 1 mm and 4 mm. NOTE - For thicknesses less than 1 mm, ISO 7765-2 should preferably be used. Thicknesses greater than 4 mm may be tested if the equipment is suitable, but the test falls outside the scope this document. The method is suitable for use with the following types of material: - rigid thermoplastic moulding and extrusion materials, including filled, unfilled and reinforced compounds and sheets; - rigid thermosetting molding and extrusion materials, including filled and reinforced compounds, sheets and laminates; - fibre-reinforced thermoset and thermoplastic composites incorporating unidirectional or multidirectional reinforcements such as mats, woven fabrics, woven rovings, chopped strands, combination and hybrid reinforcements, rovings, milled fibers and sheets made from pre-impregnated materials (prepregs).
