What is Impact Resistance?
Impact resistance refers to a material's ability to withstand cracking, breaking, or deformation when subjected to sudden external forces, such as impacts or drops. It is a critical property that directly influences the material’s safety, durability, and reliability in real-world applications.
Dart Drop Testing Standards
ASTM D1709, ISO 7765-1-1988, JIS K7124-1, GB/T 9639.1-2008
Dart Impact Testing Principle
Before starting the test, select the test method and estimate the initial impact mass and increment Δm. Once the test begins, if the first specimen fails (breaks), reduce the mass of the falling dart by Δm; if it does not fail, increase the mass by Δm. Continue testing according to this rule. After testing 20 specimens, count the number of failed specimens N:
- If N = 10, the test is complete;
- If N < 10, continue testing until the number of failed specimens reaches 10;
- If N > 10, continue testing until the number of non-failed specimens reaches 10.
Finally, the tester will automatically calculate the test result according to specific formulas.

The Importance of Falling Dart Tester
Ensure the impact resistance of packaging materials
The core function of the dart impact tester is to determine the critical point of rupture of plastic film or sheet under impact load. This is extremely important for the packaging industry.
- Transportation safety: Packaging must resist impacts from drops during transport and handling.
- Shelf performance:Accidental impacts during shelving or stacking may damage packaging and affect sales.
- User experience: Damaged packaging upon receipt harms brand image.
impact resistance testing
Comply with international standards and improve market access
Dart impact testing is usually carried out according to international standards such as ASTM D1709 and ISO 7765-1, which are quality requirements that many export products must meet.
- ASTM D1709: Method A and Method B are used to determine the resistance of films to free-fall impact respectively.
- ISO 7765-1: Applicable to free-fall impact testing of plastic films or sheets.
impact resistance testing
An important tool for quality control
During the production process, the dart tester is a key quality control device.
- Raw material screening: Test results reveal impact strength differences among suppliers, aiding in selecting quality materials.
- Process optimization: Adjust temperature, speed, and cooling during production based on test results.
- Batch consistency detection: Ensure consistent impact resistance across batches to maintain product quality.
