Falling Dart Impact Testing Machine

Product Description

Falling Dart Impact Testing Machine

Application:

It is used to measure the impact mass and energy of 50% plastic film or sheet when the plastic film or sheet with a thickness of less than 1mm is impacted by a free falling dart at a given height.

Features:

• 2 test methods of A & B and automatic determination of testing status
• Electromagnetic suspension and automatic release of the falling dart reduce the errors caused by manual operation
• Pneumatic clamping, 2 starting modes of manual and pedal switch and built-in observation light are convenient to the users operation
• Professional software supports multi-unit result display, graphic display of testing process and data export and printing
• Equipped with USB port and micro printer port which is convenient for data transmission and PC connection

Principle:

Before starting the test, choose test method, and estimate an initial mass and m. Start the test. If the first specimen fails, decrease the mass of the falling dart by m. If the first specimen is not a failure, increase the mass of the falling dart by m. Continue the test according to this rule. In brief, increase or decrease by m according to whether the former specimen is a failure or not. After 20 specimens, calculate the total number of failed specimens N. If N equals to 10, the test is over. If N is less than 10, add specimens and continue to test until N equals to 10. If N is greater than 10, add specimen and continue the test until the number of non-failure specimens reaches 10. Then the tester calculates the test results automatically according to specific formulas.
