ISO 180:2019 - Plastics — Determination of Izod impact strength

ISO 180 defines methods for determining the Izod impact strength of plastics using a pendulum-type impact tester. The test evaluates the energy required to break a plastic specimen, providing valuable data on its toughness and resistance to sudden impact.

Scope:

• Testing Methodology: Details the procedure for testing notched and unnotched specimens under standardized conditions.
• Energy Measurement: Measures energy absorbed during the breakage, normalized to the specimen’s cross-sectional area.
• Material Suitability: Applicable to thermoplastics, thermosetting plastics, and composites, whether reinforced or not.
• Environmental Factors: Allows testing under different temperatures and environmental conditions to assess material behavior.

Applications:

• Material Evaluation: Used to determine the suitability of plastics for applications requiring specific impact strength.
• Quality Control: Ensures consistency in the production of plastic materials.
• Performance Testing: Helps in understanding how plastics perform under impact conditions.
• Research and Development: Assists in improving the mechanical properties of polymers for various industrial applications.
