Falling Dart Impact Tester ISO 7765 Drop Dart Impact Testing Machine Dart Drop Impact Tester

The ISO 7765 Drop Dart Impact Testing Machine is an advanced and reliable instrument designed to evaluate the impact resistance of plastic films and sheets. Engineered to comply with ISO 7765, ASTM D1709, JIS K7124-1, and GB/T 9639.1-2008, this testing machine provides precise measurements of the energy required to cause failure in test samples under controlled free-fall dart impact conditions. With high-speed testing, user-friendly operation, and consistent performance, it is widely used in quality control laboratories across the packaging, food, pharmaceutical, beverage, and research industries.

Overview of ISO 7765 Drop Dart Impact Testing Machine

The ISO 7765 Drop Dart Impact Testing Machine applies a falling dart impact test to determine the mechanical strength of thin plastic films and flexible sheet materials. This destructive test is a critical quality assurance measure in various industrial applications to ensure the material can withstand mechanical handling and transportation stress.

By measuring the impact energy in terms of the weight of a dart dropped from a fixed height, this instrument quantifies material resistance. The test determines the mass at which 50% of test specimens fail (referred to as the 50% failure energy threshold), offering a standardized and reproducible metric for material durability and toughness.
