ASTM D6110 Charpy Impact Resistance of Notched Specimens of Plastics

    ASTM D6110 Introduction

    ASTM D6110 (Standard Test Method for Determining the Charpy Impact Resistance of Notched Specimens of Plastics) is a pendulum impact test that establishes the impact resistance of plastic materials. Measures the plastic material’s energy absorption when broken at the notch. The pendulum impact test determines the energy needed to break the standard impact specimen of a specified size under standardized conditions of specimen mounting, specimen notching (stress concentration), and notched pendulum velocity at impact. ASTM D6110 tests the toughness, fracture properties, and brittleness of plastics in industry under impact loading.

    • The applications in thermoplastics and reinforced plastics. 

    ASTM D6110 Equipment and Sample Preparation

    Specimen DetailsThermoplastics, polymer blends, and molded plastic materials.
    Specimen PreparationNotched, smooth, and uniformly machined specimens.
    Specimen DimensionsDimensions follow ASTM Charpy impact specimen requirements: length 80 mm, width 10 mm, and thickness 4 mm.

    Use of ASTM D6110

    • Carries out tests on the impact resistance of plastic materials 
    • Guides the development of material and its comparison 
    • Helps determine the nature of brittle fractures. 
    • Creates and reliably implements statistical process control (SPC) systems 

    What is Charpy impact resistance?

    Charpy impact resistance is the resistance of a material to energy absorption under sudden impact. High impact resistance means higher toughness and fracture resistance in rapid loading.

    Why is notch sensitivity important?

    The notch focuses the stress in a small region of the specimen. This condition helps engineers in assessing the impact of the loading performance of materials with cracks or defects.

    Common Challenges and Troubleshooting 

    Technical problems consist of notch dimensions, specimen alignment, specimen conditioning, and pendulum calibration. These affect the impact energy measurement. However, proper specimen preparation, proper calibration of equipment, and controlled testing conditions improve accuracy and repeatability.

    Testing Technique, Process, and Data Collection

    The technician prepares the plastic specimen. Then the technician places the specimen in the Charpy impact machine. A pendulum comes down at a set velocity and hits the specimen. The system measures the absorbed fracture energy automatically. Last, the technician notes the impact resistance data and fracture notes.

    Testing Procedures and Requirements

    The technician prepares a notched plastic specimen according to standard dimensions first. Then, the operator places the specimen in the Charpy impact testing machine, side up and side down. The pendulum hits the notched specimen at a controlled speed. The system measures the fracture absorbed energy. Lastly, the expert writes about the effects of impact and fracture on the sample.

    Analysis Results and Interpretation

    ASTM D6110 states impact resistance in kJ/m² and/or ft·lbf/in². High impact resistance values mean high toughness and resistance to sudden fracture. Lower values mean greater brittleness and less impact performance. Engineers use these findings to evaluate, improve formulations, and assess product durability.
