The tester is mainly used to determine the resistance to external blows of the thermalplastics pipes of circular crosssection.Test pieces are subject to blow from a falling striker,of specified mass and shape,dropped from a known height onto specified positions 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.
Standard: ISO3127,BS EN1411,BS EN744,ASTM D2444 and the equivalent.

characteristic

1.Catching rate of anti-rebound device is 100%.
2.Imported AC servo system guarantes the high locating precision and fast rising speed.
3.Impact height may be set between 50 and 2000mm,also impact height may be calibrated automatically.
4.Automatic security devices are provided in this instrument(specimen door,anti-rebound and striker window safeguard etc).
