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 nominal 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 to 4 mm. 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 moulding and extrusion materials, including filled and reinforced compounds, sheets and laminates; — fibre-reinforced thermoset and thermoplastic composites incorporating unidirectional or multi-directional reinforcements such as mats, woven fabrics, woven rovings, chopped strands, combination and hybrid reinforcements, rovings, milled fibres and sheets made from pre-impregnated materials (prepregs). The method is also applicable to specimens which are either moulded or machined from finished products, laminates and extruded or cast sheet. The test results are comparable only if the conditions of preparation of the specimens, their dimensions and surfaces as well as the test conditions are the same. In particular, results determined on specimens of different thickness cannot be compared with one another (see Annex E). Comprehensive evaluation of the reaction to impact stress can be obtained by determinations made as a function of impact velocity and temperature for different material 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 (see above) for tests by this method. Test data developed by this method is not intended to be used for design calculations. However, information on the typical behaviour of the material can be obtained by testing at different temperatures and impact velocities (see Annex D) by varying the thickness (see Annex E) and by testing specimens prepared under different conditions. It is not the purpose of this document to give an interpretation of the mechanism occurring on every particular point of the force-deflection diagram. These interpretations are a task for scientific research.
Abstract
Overview
ISO 6603-2:2023 - Plastics: Determination of puncture impact behaviour of rigid plastics - Part 2: Instrumented impact testing specifies an instrumented test method to measure the puncture impact behaviour of rigid plastics using instruments that record force and deflection (or force‑time) at a nominal constant striker velocity. Applicable to flat specimens with thicknesses from 1 mm to 4 mm, the standard produces force‑deflection diagrams and derived parameters (maximum force, puncture deflection, puncture energy) for detailed material characterization.
Key technical topics and requirements
- Test principle: instrumented puncture impact with recorded force‑deflection or force‑time curves at nominal constant striker velocity.
- Specimen scope: rigid thermoplastics, thermosets and fibre‑reinforced composites (moulded, extruded, cast or machined specimens).
- Thickness limitation: results are valid for specimens 1–4 mm thick; comparisons across different thicknesses are not permitted (see Annex E).
- Measured parameters: impact velocity, force, deflection, energy (integral of force‑deflection), maximum force (FM), puncture deflection (lP) and puncture energy (EP).
- Test conditions and comparability: specimen preparation, dimensions, surface finish, conditioning and test climate must be identical for comparable results.
- Guidance and annexes: interpretation of complex curves, friction effects, clamping methods, tough/brittle transitions, thickness influence, failure classification and precision data (Annexes A–G).
- Limitations: test data are for material characterization and trend analysis (e.g., temperature, velocity, crystallinity, moisture effects) - not intended for direct design calculations or to fully predict finished‑product behaviour.
Practical applications and users
Who uses ISO 6603-2:2023:
- Materials engineers and R&D teams characterizing impact toughness of rigid plastics and composites.
- Test laboratories performing standardized puncture impact testing and producing force‑deflection data.
- Manufacturers of plastic parts and sheets seeking comparative performance data (e.g., for grade selection, QA, or failure analysis).
- Regulatory and certification bodies requiring reproducible impact characterization.
How organizations use it:
- Generate force‑deflection and puncture energy metrics to compare materials, additives or processing conditions.
- Study tough/brittle transitions by testing across temperatures and velocities.
- Evaluate influence of reinforcement, filling or moisture on impact response.
