ASTM D1709 Free-Falling Dart Method Impact Tester Stair Case Dart Impacting Test Machine Impact Resistance Test

The ASTM D1709 Free-Falling Dart Method Impact Tester is a precision-engineered laboratory instrument designed to measure the impact resistance of plastic films and sheets. This critical testing device evaluates the energy required to cause material failure under controlled impact conditions, aligning with the rigorous criteria of ASTM D1709, ISO 7765, JIS K7124-1, and GB/T 9639.1-2008 standards.

Ideal for manufacturers and quality assurance teams in packaging, food, pharmaceuticals, and other industries, this impact tester ensures material performance under real-world stress conditions. By determining the weight of a free-falling dart that results in a 50% failure rate among test specimens, the device provides quantitative data that supports material optimization, compliance, and product development.

Product Overview: Reliable Testing for Impact Resistance

The ASTM D1709 Free-Falling Dart Method Impact Tester offers two methods—Method A and Method B—for evaluating the impact strength of plastic films and sheets:

• Method A: Uses a dart with a diameter of 38±1 mm and an impact height of 660 mm.

• Method B (optional): Utilizes a larger dart of 50±1 mm diameter and a higher impact height of 1500 mm.

The instrument delivers highly accurate test results, expressed in grams (g) and joules (J), with a resolution of 0.1 g or 0.1 J. This enables precise analysis of material toughness, consistency, and suitability for applications such as flexible packaging, medical films, laminated materials, and industrial sheets.

Key Features of the ASTM D1709 Free-Falling Dart Method Impact Tester

To ensure high performance and user-friendly operation, the tester is equipped with advanced features, including:

• Intelligent PLC Control System: Ensures stable, programmable testing operations.

• User-Friendly Touch Screen Interface: Simplifies navigation and configuration.

• Electromagnetic Suspension: Guarantees accurate and repeatable dart release.

• Pneumatic Clamping: Ensures firm and consistent sample fixation.

• Dual Testing Methods: Offers both A and optional B test modes for versatile applications.

• Integrated Observation Light: Enhances sample visibility during testing.

• Micro-Printer: Enables quick and clear printout of test results.

• Professional Data Analysis Software (Optional): Facilitates in-depth results interpretation and digital record-keeping.

• Manual and Foot Switch Operation: Enhances operational flexibility.

These features make the ASTM D1709 Free-Falling Dart Method Impact Tester suitable for routine quality control, R&D, and conformance testing in both production and laboratory settings.

Technical Specifications

Applications Across Industries

The ASTM D1709 Free-Falling Dart Method Impact Tester is widely applied in testing:

• Packaging Films: Including polyethylene (PE), polypropylene (PP), polyester (PET), and multi-layer structures used in flexible packaging.

• Medical Films: For sterile barrier systems and pharmaceutical packaging.

• Food Contact Materials: Ensuring impact durability in packaging for beverages, snacks, frozen foods, and more.
