Portāls Falling Dart Impact Test is a key procedure used to assess the strength and durability of films, particularly in industries where packaging materials need to withstand sudden impacts. The test simulates real-world conditions where packaging materials may be exposed to physical stresses.

What is the Dart Impact Test?

Portāls Falling Dart Impact Test is a widely used test to evaluate the resistance of films and flexible materials to impact damage. In this test, a dart is dropped from a set height onto the film specimen, and the energy absorbed by the material is measured. The test helps manufacturers determine the material’s toughness and its ability to withstand real-world handling, which is critical for packaging in various industries such as food, medical, and sterile packaging.

Portāls Falling Dart Impact Test is especially important for materials used in food films un sterile packaging, where the packaging needs to protect contents from external forces during transportation and storage. By performing this test, manufacturers can ensure their materials meet the necessary durability requirements.

ASTM D1709 Standard for Dart Impact Test

Portāls ASTM D1709 standard provides the guidelines for performing the Dart Impact Test on plastic films. This standard specifies the test procedure, the required equipment, and the interpretation of results. The test involves dropping a dart of known mass from a predefined height onto a film sample. The energy absorbed by the film before it punctures is recorded, providing valuable insights into the material’s impact resistance.

The ASTM D1709 standard outlines two test methods: Method A and Method B. A metode uses a smaller dart (38 mm) and a lower weight range (50-2000g), while B metode uses a larger dart (50 mm) and a higher weight range (300-2000g). Both methods ensure consistent and comparable results, allowing manufacturers to test different types of films under various conditions.

Key Features of the FDT-01 Falling Dart Impact Tester

Cell Instruments' FDT-01 krītošo šautriņu trieciena testeris is an advanced tool designed to perform accurate Impact Tests with efficiency and ease. Here are some of the key features of the FDT-01:

1. PLC vadība un HMI skārienekrāns: The FDT-01 is controlled by a programmable logic controller (PLC), offering industrial-level stability. The human-machine interface (HMI) touch screen ensures ease of use, allowing for quick setup and operation.
2. Two Test Methods: The tester supports both A metode un B metode, giving flexibility in testing various types of films and materials.
3. Pneumatic Sample Clamping: The pneumatic clamping system ensures the film specimen is securely held in place during testing, improving the consistency and accuracy of results.
4. Automatic Falling Dart Mechanism: The electromagnetic suspension and automatic dart release system ensure precise and repeatable testing, eliminating manual errors.
5. Test Results Displayed in Grams and Joules: The FDT-01 provides test results in both grams (weight) and joules (energy absorbed), helping manufacturers assess the material’s performance comprehensively.
6. Dot Matrix Micro-Printer: The tester includes a built-in micro-printer for immediate data output, allowing for quick analysis of test results.
7. Professional Software (Optional): Optional software is available for further data analysis and storage, enhancing the testing process for advanced users.
8. Safety Features: The FDT-01 is equipped with both test buttons and a foot switch, ensuring safe and easy operation during testing.

How to Perform the Drop Dart Impact Test

To perform the Falling Dart Impact Test, follow these simple steps:

1. Prepare the Sample: Cut the film specimen to the required size (minimum size of 150 mm x 150 mm).
2. Set Up the Test Equipment: Ensure the FDT-01 krītošo šautriņu trieciena testeris is properly calibrated and the specimen is securely clamped in place using the pneumatic clamping system.
3. Select Test Method: Choose either A metode or B metode, depending on the type of film and testing requirements.
4. Conduct the Test: Initiate the test by pressing the start button or foot switch to release the dart. The dart will fall from a specified height and impact the film sample.
5. Analyze the Results: After the test, the results will be displayed in grams and joules. The energy absorbed by the material before puncturing will indicate the film’s impact resistance.

Applications of the Dart Impact Test

Portāls Falling Dart Impact Test is widely used in industries where film materials are required to provide protection against physical damage, such as:

• Pārtikas iepakojums: Ensuring the durability of packaging materials that will protect food from contamination and physical damage during shipping and handling.
• Sterile Packaging: Testing packaging materials used for medical and pharmaceutical products to ensure they remain intact and provide proper protection.
• Consumer Products: Testing films used for electronics, textiles, and other consumer goods that require durable packaging.
• Farmaceitiskie produkti: Ensuring that pharmaceutical packaging maintains the integrity of sensitive products during transportation.
