Application
It is used to determine the resistance to external blows of thermoplastics pipes of circular cross-section.
Test pieces are subject to blow from a falling striker, of specified mass and shape, dropped from a known height onto specified position around the circumference of the test piece.
The true impact rate of the batch, or production run from an extruder, is estimated.
The maximum value acceptable for the TIR is taken to be 10%.
There are two test methods--round-the-clock method and staircase method.
Features
· Anti-rebound device has the catching rate of 100%.
· High precise servo system guarantees the high locating precision and fast rising speed.
· Adjust height between 50 to 2000mm; Also the impact height may be automatically calibrated.
· Automatic personal safeguards are considered, e.g. specimen door, anti-shock and striker window safeguard etc. Test can only be carried out when the test chamber and window are closed.
