1. Product name: Digital drop hammer impact tester
2. Specification model: DT-450
3. Based on standards: GB/T 2611-2007 "General Technical Requirements for Testing Machines"
JB/T 6147-2007 "Technical Requirements for Testing Machine Packaging, Packaging Marking, Storage and Transportation"
ASTM D3763 "Plastic High-speed Puncture Test Method"
4. Product Description:
The double-guide column design is used to complete the plastic sheet and film puncture impact test. The hammer is driven by the moving beam to lift and store energy, and the pneumatic hanging hammer mechanism releases the hammer; the sample is fixed on the clamping device above the workbench by the pneumatic clamping device, and the hammer falls freely to impact the sample. The digital display touch screen controls the hanging hammer to rise to the specified height and displays the energy value, and the manual button releases the impact hammer.
