Crush squeeze tester

The falling weight tester is used to determine the external impact resistance of thermoplastic pipes using the staircase or round-the-clock method according to EN744. According to EN 744 , EN 1411 , ISO 3127 , ASTM D 2444 , digital height control , touch display , automatic control of number of impacts , motorized sample table

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. According to ISO 7765, ASTM D1709, touch displat, thermal printer report out, USB data out to excel, pneumatic sample grip

The RCP tester conveniently and accurately determines the critical pressure and critical temperature for rapid crack propagation in PE pressure pipes. According to ISO 13477 , motorized height adjust , trolley for sample , freezer , 40 bar air compressor , ring and baffles for samples , computer controlled
