Plastic films used in packaging, medical devices, industrial products, and consumer goods must withstand accidental impacts during manufacturing, transportation, storage, and end use. A film that tears or punctures easily can lead to product damage, contamination, customer complaints, and increased production costs. JIS K 7124-1 provides a standardized method for evaluating the impact resistance of plastic films using the free-falling dart method, allowing manufacturers to compare materials objectively and maintain consistent product quality.
De FDT-01 Vallende Dart Impact Tester from Cell Instruments is designed to perform JIS K 7124-1 testing with high precision and repeatability. It automates the staircase testing procedure, minimizes operator influence, and delivers reliable impact resistance data for quality control, research, supplier qualification, and product development.
What Is JIS K 7124-1?
JIS K 7124-1 is the Japanese Industrial Standard that specifies the staircase method for determining the impact resistance of plastic film and sheeting using a free-falling dart. The test determines the dart mass that produces approximately a 50% probability of specimen failure, providing an effective measurement of film toughness.
The method is widely used because it:
- Simulates accidental impact during handling and transportation
- Produces highly repeatable laboratory results
- Allows comparison between different film formulations
- Supports process optimization and quality assurance
- Provides objective acceptance criteria for suppliers
Manufacturers of flexible packaging often use JIS K 7124-1 alongside international standards to ensure products meet customer specifications worldwide.
Why Is the Falling Dart Test Important?
De falling dart test evaluates how well a flexible material resists sudden impact. Unlike tensile testing, which measures gradual loading, impact testing reproduces the rapid loading conditions encountered during real-world handling.
Typical benefits include:
- Preventing package failure during shipping
- Optimizing film thickness without sacrificing strength
- Comparing resin formulations
- Evaluating multilayer structures
- Verifying production consistency
- Supporting product certification
Door JIS K 7124-1, manufacturers can improve both product reliability and production efficiency.
How Does the JIS K 7124-1 Falling Dart Impact Test Work?
De falling dart impact method uses a weighted hemispherical dart that falls freely from a specified height onto a clamped specimen.
The staircase procedure gradually adjusts the dart weight according to whether each specimen passes or fails until sufficient data are collected to calculate the 50% failure point.
Typical workflow includes:
- Prepare specimens according to the standard.
- Secure the specimen using the pneumatic clamp.
- Select Method A or Method B.
- Install the appropriate dart weight.
- Release the dart using the electromagnetic release mechanism.
- Record whether the specimen failed.
- Continue the staircase sequence.
- Automatically calculate the impact resistance result.
The final result is typically expressed as:
- Critical dart mass (g)
- Impact energy (J)
These values provide a quantitative measurement of film impact resistance.
