Falling Dart Impact Tester

Product Name：

Falling Dart Impact Tester

Description：

WESTINGAREA supplied L583561 Falling Dart Impact Tester have the excellent performance displayed as:


Falling dart impact tester is designed and manufactured according to Chinese state
standard GB 9639 and ASTM D 1709. It is applicable in energy test that causes plastic
films and foils to fail under specified conditions of impact of a free-falling dart.
This energy is expressed in terms of the weight of the dart falling from a specified
height which would result in 50% failure of specimens tested

1. Characteristics

* Compatible with state and international standards.
* Novelty mechanical sculpts, considerate design.
* Two test methods integration: A & B.
* Special lighting design, easy to observe.
* Micro-computer processes test results.
* Intelligent test enhances test efficiency.
* Pneumatic clamping and releasing decrease test time and errors.
* Test procedure requires no manual drawing and mark, data and parameters are
displayed by LCD.
* System identifies, calculates test data automatically, and requires no manual
intervention.
* Test stops automatically, results are displayed by multifold units, micro-printer
prints results.

2. Test Principle

At the beginning of the test, choose a test method, and estimate an initial mass and
Δm. Test, if the first specimen is failure, decrease the mass of the falling dart by
decreasing poise of Δm. If the first specimen is not failure, add the mass of the
falling dart by increasing poise of Δm. Test as the same. In brief,increase or decrease
the Δm according to whether the former specimen is failure or not. After 20 specimens,
calculate the total number of failure specimens N. If N equals to 10, test over. If N
is less than 10, add specimen and continue to test until N is equal to 10. If N is more
than 10, add specimen and continue the test until the number of non-failure specimen is
10. Then calculate the test results according to special formula.

3. Operation demo

Power on -- choose test method -- estimate initial impact mass and
Δm -- increase or
decrease the Δm according to impact result -- system calculates
automatically -- estimate
whether the result satisfy the condition of stopping -- display test
results -- print test
results -- test over
