FDT-01 Falling Dart Impact Tester

The falling dart impact tester is a specialized instrument used to assess the impact strength of plastic films, composite materials, foils, and paper with a thickness of less than 1mm. This test evaluates the material’s resistance to impact by determining the energy required to cause failure under controlled conditions. It is widely used in packaging, food, pharmaceutical, and electronics industries to ensure product durability and performance.

How the Free Falling Dart Test Works

The free falling dart test involves the following steps:

  1. A film sample is securely clamped in place.
  2. A dart with a pre-determined weight is suspended electromagnetically.
  3. The dart is released from a controlled height.
  4. The impact strength is recorded based on pass/fail results from multiple trials.
  5. The system calculates the material’s impact resistance in grams or joules.

Dart Impact Test Methods & Standards

ASTM D1709 & ISO 7765-1

The dart impact test for plastic film follows internationally recognized standards such as ASTM D1709 and ISO 7765-1, ensuring consistent and accurate results. These standards outline the methodology for conducting a free falling dart test, where a weighted dart drops from a specified height onto a film sample, determining the minimum weight required to cause material failure.

Test Methods: Method A & Method B

Both ASTM D1709 and ISO 7765-1 define two distinct test methods:

  • Method A: Uses a dart with a 38mm diameter and an impact height of 660mm.

  • Method B: Uses a dart with a 50mm diameter and an impact height of 1500mm (optional in some test setups).
