DH-BMC-A Economical Falling Dart Impact Tester ASTM D1709 Dart Impact Tester

 

Characteristics:

 

1. Mechanical model is novel, operation simple and reasonable design;

2. Contains A method and B method two kinds of test mode;

3. Sample automatic clamping, clamping samples after high flatness, no slipping, fixture success rate 100%, effectively reduce the test personnel operating strength and skills;

4. Automatic discharge dart mechanism, make the dart body release more flexible, freely;

5. Automatic capturing institutions, improve the security of the instruments, make the test operation more simple. Reliable, cap-ture the successful rate was 100%;

6. Multiple interlock type safety device, effectively prevent the machine misoperation, greatly improving the instrument operation safety;

7. Sample bottom lighting device, we can clearly see sample damage or breakage (namely penetration), make more accurate data.

 

Standards: GB/T9639, ISO 7765-85, ASTMD1709

 

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:

 

l 2 test methods of A & B and automatic determination of testing status

l Electromagnetic suspension and automatic release of the falling dart reduce the errors caused by manual operation

l Pneumatic clamping, 2 starting modes of manual and pedal switch and built-in observation light are convenient to the user's operation

l Professional software supports multi-unit result display, graphic display of testing process and data export and printing

l 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 Δm. Start the test. If the first specimen fails, decrease the mass of the falling dart by Δm. If the first specimen is not a failure, increase the mass of the falling dart by Δm. Continue the test according to this rule. In brief, increase or decrease by Δm 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.
