What Is ISO 180 Izod Impact Strength?
ISO 180 is a test standard that specifies a method for determining the Izod impact strength of plastic materials. The test assesses the plastic material’s resistance to impact loading. The test measures the energy that the plastic material can absorb under impact loading using a pendulum hammer.
This test method is essential for determining the toughness of plastic materials. The test is important for assessing plastic materials subjected to impact loading. The test helps manufacturers understand the performance of plastic materials under impact loading.

Our ISO 180 Testing Procedure
Specimen Preparation
Specimens (typically ~80 × 10 × 4 mm) are prepared with or without a V-notch and conditioned at ~23°C and 50% RH.
1Specimen Mounting
The specimen is vertically clamped in the Izod impact tester, with the notch facing the striking edge (for notched tests).
2Pendulum Impact
A calibrated pendulum hammer strikes the specimen, causing it to fracture under sudden impact.
3Energy Measurement & Calculation
The instrument measures the energy absorbed during fracture and calculates the Izod impact strength based on the specimen dimensions.

ISO 180 Izod Impact Strength FAQs
ISO 180 is a test standard that measures the impact resistance of plastics. The test determines the amount of energy that the plastic absorbs after the pendulum hammer hits it, thus giving an idea of the plastic’s toughness when subjected to an impact.
ISO 180 is primarily used to conduct tests on plastics and polymer-based materials such as thermoplastics, thermosets, and fibre-reinforced composites.
Izod tests help manufacturers understand the behaviour of the material when it is subjected to a sudden mechanical impact. It is critical for parts that could be subjected to shocks, such as car parts, packaging materials, electronic devices, and other consumer products.
The results obtained from the impact test can depend on the thickness of the test piece, the quality of the notch, the temperature, the makeup of the material, and the rate at which the test is conducted.
ISO 180 testing is commonly applied in various industries such as the automotive industry, the packaging industry, the electronics industry, the construction industry, the consumer goods industry, and the polymer industry.
An ISO impact tester measures a material’s resistance to sudden impact or fracture. A pendulum strikes a prepared specimen, and the energy absorbed during fracture is calculated from the pendulum’s energy loss. Depending on the material and test method, ISO 179 is commonly used for Charpy impact testing of plastics, while ISO 180 covers Izod impact testing. Results help compare impact resistance and material toughness.
Impact strength is commonly reported in kilojoules per square metre (kJ/m²) or joules per square centimetre (J/cm²) when the absorbed impact energy is normalized by the specimen’s cross-sectional area. Some tests report absorbed energy directly in joules (J). The correct unit depends on the test method, specimen geometry, and material being tested.
