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 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.
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 D6110 test method is for measuring plastics’ ability to resist fracture under sudden flexural shock (high-strain-rate impact loading). It quantifies the energy a notched plastic bar absorbs during complete fracture via a single pendulum swing, with results primarily reported as absorbed energy per unit specimen width (J/m). Similar with ISO 179 (plastic Charpy impact) but has entirely distinct technical specifications.

ISO 9653 Adhesives — Test method for shear impact strength of adhesive bonds
ISO 9653 defines a unified pendulum impact test to quantify the comparative shear impact resistance of bonded joints under instantaneous shock load. UnitedTest, a leading material testing equipment manufacturer since 1985, designs and produces ISO 9653 compliant pendulum impact testing machines for determining the shear impact strength of adhesive bonds between wood-to-wood, metal-to-metal, and plastic-to-plastic substrates. Our adhesive shear impact tester employs a calibrated pendulum mechanism delivering a controlled 3.4 m/s impact head velocity, absorbing energy at the moment of bond failure and reporting the impact value in J/m² — fully conforming to ISO 9653, EN 29653, ASTM D950 and GB/T 6328.
