Drop Dart (Free-falling Dart) Impact Tester

Drop Dart (Free-falling Dart) Impact Tester

Model: XJB-30E, ASTM D1709, ISO 7765-1

XJB-30E Heavy duty frame falling dart impact testing machine mainly used to test plastic, film, or sheet thickness below 1mm, impact by falling dart, check the energy when 50% of test specimen broken.

Conform with standard: ISO 7765-1, ASTM D1709, GB 9639.


Scope:

Falling dart impact is a traditional method for evaluating the impact strength or toughness of a plastic film. This test uses a single dart configuration and a single drop height, while varying the weight of the dart. Test results can be used either as a quality control evaluation or for end use comparisons.

ASTM D1709 Falling Dart Impact Resistance of Plastic Film

ASTM D1709: Standard Test Methods for Impact Resistance of Plastic Film by the Free-Falling Dart Method


ASTM D1709 test methods cover the determination of the energy that causes plastic film to fail under specified conditions of impact of a free-falling dart. This energy is expressed in terms of the weight (mass) of the missile falling from a specified height which would result in 50 % failure of specimens tested.

ISO 7765-1 Impact resistance by the free-falling dart method

ISO 7765-1:1988 Plastics film and sheeting — Determination of impact resistance by the free-falling dart method 

Part 1: Staircase methods


ISO 7765-1 and ASTM D1709 specifies methods for the determination of the energy, that causes plastics films and sheet less than 1 mm in thickness to fail under specified conditions of impact of a free falling dart from a specified height, that would result in failure of 50 % of the specimens tested. Two methods are described. Method A employs a dart with 38 mm diameter hemispherical head, dropped from a height of 0,66 m, and method B employs a dart with a 50 mm diameter hemispherical head dropped from a height of 1,50 m. The measurement technique is the staircase method.
