ISO 179: Plastics -- Determination of Charpy impact properties
ASTM D6110: Standard Test Method for Determining the Charpy Impact Resistance of Notched Specimens of Plastics.
ISO 179 specifies a method for determining the Charpy impact strength of plastics under defined conditions. A number of different types of specimen and test configurations are defined. Different test parameters are specified according to the type of material, the type of test specimen and the type of notch.
The method can be used to investigate the behaviour of specified types of specimen under the impact conditions defined and for estimating the brittleness or toughness of specimens within the limitations inherent in the test conditions. It can also be used for the determination of comparative data from similar types of material.
ISO 180 specifies unified methods to measure the Izod impact strength of plastics under standardized conditions, evaluating material brittleness and toughness via pendulum impact tests.
ASTM D6110: Standard Test Method for Determining the Charpy Impact Resistance of Notched Specimens of Plastics
ASTM D6110 test method is used to determine the resistance of plastics to breakage by flexural shock as indicated by the energy extracted from standardized pendulum-type hammers, mounted in standardized machines, in breaking standard specimens with one pendulum swing. This test method requires specimens to be made with a milled notch. The notch produces a stress concentration which promotes a brittle, rather than a ductile, fracture. The results of this test method are reported in terms of energy absorbed per unit of specimen width.
The tests require specimens made with a milled notch, hence the test is often referred to as the “notched bar impact test”. In both the Charpy and Izod Tests, the notch produces a stress concentration which promotes a brittle, rather than a ductile, fracture.
ASTM D1822 Tensile Impact Energy to Break Plastics and Electrical Insulating Materials
ASTM D1822 standard outlines test procedures to find the energy required to rupture tension-impact specimens of plastic or electrical insulating materials. Test materials that are too bendable or too thin to be tested in accordance with the ASTM D256 standard are ideal for this test along with more rigid materials.
ISO 9854 specifying Charpy pendulum impact test to evaluate low-temperature and room-temperature toughness of fluid-transporting thermoplastic pipes. Part 1 defines universal test rules while Part 2 sets customized testing parameters for individual thermoplastic pipe grades (PVC‑U, PE, PP‑R, ABS, PVC‑O, PVC‑HI, etc.). It is a supplementary Charpy test alternative when the reference full-pipe drop-weight impact test (ISO 3127) cannot be implemented for factory QC or material R&D.
ISO 8256:2023 Plastics — Determination of tensile-impact strength
ISO 8256 specifies two methods (method A and method B) for the determination of the tensile-impact strength of plastics under defined conditions. The tests can be described as tensile tests at relatively high strain rates. These methods can be used for rigid materials (as defined in ISO 472), but are especially useful for materials too flexible or too thin to be tested with impact tests conforming to ISO 179 or ISO 180.These methods are used for investigating the behaviour of specified specimens under specified impact velocities, and for estimating the brittleness or the toughness of specimens within the limitations inherent in the test conditions. Similar with standard ASTM D1822.
These methods are applicable both to specimens prepared from moulding materials and to specimens taken from finished or semi-finished products (for example mouldings, films, laminates, or extruded or cast sheets).
