Drop Dart (Free-falling Dart) Impact Tester

Drop Dart (Free-falling Dart) Impact Tester

Model: XJB-30E, ASTM D1709, ISO 7765-1. ISO 6603-1

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. ASTM D5628, ISO 6603-1.


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.

ISO 6603-1 Rigid plastics falling dart puncture-impact test

ISO 6603-1 specifies falling-dart methods to measure the puncture‑impact performance of rigid plastics using only the 50% impact‑failure energy (E₅₀) threshold, without recording force–time or force–deflection curves.

ASTM D5628 Falling Tup Impact Resistance Test of Rigid Plastics

ASTMD5628 specifies a falling‑dart/tup method to measure the threshold impact‑failure energy for flat rigid plastics. It uses the Bruceton Staircase (Up‑and‑Down) Method to determine the energy causing 50% of specimens to fail (mean‑failure energy, MFE).

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.

ASTM D5420 Gardner falling weight impact test for flat rigid plastic

ASTMD5420 measures the relative ranking of materials based on the energy required to crack or break a plastic sheet when struck by a falling weight (the "Gardner Impact" method).



ASTM D3029 Impact Resistance of Flat Rigid Plastic By Falling Tup Weight

ASTMD3029 is designed to determine the relative ranking of rigid plastic materials based on the energy required to crack or break them under specified impact conditions.
