Board puncture resistance tester measures the energy required to puncture board with a pyramidal head affixed to a pendulum arm. This energy includes the energy to tear the material and the energy to bend it out of the way of the point. Board puncture resistance tester features 1. PVC menu type operation panel 2. Microcomputer control with data statistics, storage and printing function 3. Auto measuring and intelligent judgment, real time display of test result 4. Four gears adjustable 5. Protection design and stable performance Board puncture resistance tester technical data Test range: (1~48)J Four gears: A ＜6J; B＜12J; C＜24J; D＜48J; Resolution: 0.001J Pressure head: (100±2)kpa Friction sleeve resistance: ＜0.25J Pyramidal head: edge length 60mm×60mm×60mm height 25±0.7mm Dimension: 900mm*410mm*800mm Weight: 110kg Board puncture resistance tester standards ISO 3036 Board -- Determination of puncture resistance ASTM D781 standard test methods for puncture and stiffness of paperboard,and corrugated an solid fiberboard DIN 53142 Testing of board; puncture test TAPPI T803 Puncture test of container board
