PIT-01 Pendulum Impact Tester

The pendulum impact tester measures a material’s ability to resist sudden impacts by recording the energy required to cause rupture or penetration. ASTM D3420 provides a standardized method to evaluate the impact resistance of plastic films, ensuring consistent quality control and material characterization. Commonly tested materials include plastic films, laminates, composites, foils, and paper used in packaging, automotive, and construction applications.

How the Pendulum Impact Tester Works

The PIT-01 Pendulum Impact Tester by Impacttesting.net is designed to provide precise and repeatable impact resistance measurements. The testing process involves:

  1. Specimen Preparation: A sample of uniform thickness and consistency is selected.
  2. Specimen Clamping: The film is secured in place using a pneumatic clamping system.
  3. Pendulum Release: The pendulum, equipped with an impact head, is automatically released from a predefined height.
  4. Impact Measurement: The energy absorbed by the material upon impact is recorded.
  5. Data Analysis: The results are displayed on a digital interface, with an optional microprinter for immediate reporting.

ASTM D3420 and Spencer Impact Test

ASTM D3420 – Test Method for Pendulum Impact Resistance of Plastic Film

ASTM D3420 specifies a method for determining the impact resistance of plastic films by measuring the energy required for a pendulum impactor to penetrate a test specimen. The test is designed to provide insights into a material’s dynamic tensile behavior under high-strain-rate conditions, making it essential for packaging material evaluation.

Key aspects of ASTM D3420 include:

Measurement of energy loss due to the impact of a pendulum probe on the test specimen.
Two procedures (A and B) differing in sample size, with Procedure B often referred to as the Spencer Impact Test.
Importance in applications requiring high-impact resistance, such as food and pharmaceutical packaging films.

Spencer Impact Test: A Specialized Variation

The Spencer Impact Test is a variant of ASTM D3420, typically associated with Procedure B, which uses an 89-mm diameter specimen clamp. This method is widely used for evaluating films used in flexible packaging, ensuring that materials can withstand mechanical stress without tearing or puncturing.
