Free Falling Dart Impact Tester Features in Detail

Technical Specifications

Standard Compliance

The Free Falling Dart Impact Tester strictly complies with:

• ASTM D1709 – Standard Test Method for Impact Resistance of Plastic Film by the Free-Falling Dart Method

• ISO 7765 – Plastics—Film and sheeting—Determination of impact resistance by free-falling dart

These standards ensure that your testing procedures meet global quality and safety benchmarks.

Who Needs the Free Falling Dart Impact Tester

This instrument is ideal for a range of industries where packaging and plastic film performance is mission-critical. Primary users include:

• Packaging Manufacturers: Ensure high-quality film rolls for bags, pouches, and wraps.

• Quality Control Laboratories: Monitor production consistency and compliance with international standards.

• Pharmaceutical Industry: Confirm integrity and robustness of primary packaging materials.

• Food & Beverage Industry: Validate packaging film strength for products requiring barrier protection and durability.

• Colleges and Universities: Use for teaching and research purposes in material science and polymer engineering.

How It Works

1. Sample Preparation: A plastic film specimen of at least 150 mm × 150 mm is cut and fixed using the pneumatic clamp.

2. Dart Selection: Choose appropriate dart weight and method (A or B) based on the material type.

3. Testing: The dart is released from a fixed height, striking the center of the film.

4. Evaluation: If the dart punctures the film, it is considered a failure. Results are calculated based on dart mass and height.

5. Data Output: Results are displayed on the screen and can be printed or exported via software.

Why Impact Testing Matters

Material failure due to insufficient impact resistance can result in serious issues during transportation and storage—especially for vacuum-sealed, perishable, or sterile products. By conducting dart impact tests, manufacturers gain critical insights into:

• Material selection and design optimization

• Production quality control

• Supply chain reliability

• Customer satisfaction and safety assurance

Optional Software for Data Analysis

The optional professional software provides enhanced capabilities for managing and analyzing test results. Features include:

• Data trending and graphical output
