ASTM D1709 Impact Resistance of Plastic Film by the Free-Falling Dart Method

ASTM D1709 is a standard test method used to measure the impact resistance of plastic films using a by the Free-Falling Dart. The test involves dropping a weighted dart onto a plastic film specimen and assessing its ability to withstand impact without puncturing or tearing. ASTM D1709 test method is useful to evaluate the durability and strength of plastic films used in various applications.

Introduction to ASTM D1709

ASTM D1709 provides a standardized procedure for determining the impact resistance of plastic films. The test method simulates real-world scenarios where films may experience impact forces, such as during transportation or handling. By assessing the film’s ability to resist punctures and tears, manufacturers and users can ensure that the films meet specific quality and performance requirements.

ASTM D1709 Test Method

ASTM D1709 employs a free-falling dart impact tester, consisting of a guided drop tower and a dart assembly. The dart assembly includes a weighted dart, typically made of steel, with a specified mass and a hemispherical head. The test is conducted in the following steps:

Test ProcedureThe plastic film specimen is clamped onto a circular frame, creating a taut surface for the impact test. The dart assembly is raised to a specified height within the drop tower. The dart is released to free-fall and strike the center of the film specimen. The test is repeated using different incremental dart masses to assess a range of impact energies.
Observation and ReportingAfter each impact, the film specimen is examined for punctures or tears. The test result is reported as the maximum dart energy or the mass of the dart that caused failure. 

ASTM D1709 Specimens

Specimen detailsASTM D1709 is applicable to plastic films, including polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET).
Specimen dimensionsRectangular or circular plastic film specimens are prepared according to specified dimensions.
Specimen preparationThe specimens are ensured to be free from any visible defects, wrinkles, or creases.

ASTM D1709 Results

The test method ASTM D1709 determines the impact resistance of the plastic film by the maximum energy or dart mass required to cause failure.  Higher impact resistance values indicate better durability and resistance to punctures or tears. The test results are used for quality control, product development, and material selection.
