Drop Hammer Test Equipment for International Standards Compliance
Designed to comply with international testing standards for consistent and comparable results, this falling weight impact testing machine ensures reliable performance evaluation.
Application
Crafted to satisfy testing requirements in ISO3127 and equivalent normative documents, this falling weight impact testing machine is extensively adopted within research laboratories, third-party inspection institutions, and production facilities engaged with plastic pipes such as PVC-U and PVC-O. It evaluates the impact-resistant performance of pipe specimens, serving as a preferred testing apparatus for building-material manufacturers and research-oriented establishments.
Fitted with a complete drop-hammer assembly covering a mass scope from 0.5 kg up to 16 kg, the unit enables automatic calculation of impact height alongside real-time visual readout of relevant data. Supporting both the pass-fail method and staircase-gradient testing approach, this equipment delivers user-friendly workflows while maintaining high-level operational safety and dependable running performance.
Testing Principle
Specimens receive impacts delivered by a falling striker with defined mass and geometry, which is released from a predefined height onto designated positions across the test sample.
Test severity may be modulated by adjusting either the striker mass, the drop height, or both. Modifying TIR values outside the stipulated specifications shall not be adopted as a valid technical means to alter test severity.
The maximum permissible TIR threshold is set at 10%.
Product Features
- Built-in safety protection mechanism fully complies with the 89/392/EEC machinery safety directive
- Industrial-grade colorful human-machine interface paired with PLC distributed control architecture for outstanding operational stability and reliability
- Impact height supports arbitrary parameter setting within 200mm to 2000mm with 100% capture efficiency throughout the entire height adjustment range
- Impact hammer adopts vacuum adsorption technology for automatic release and secondary locking capture with maximum operating speed of 2 m/s
- Automatic lifting height calibration with tolerance controlled within ±1mm relative to preset height value
- Standalone dedicated impact hammers with each corresponding to specific impact energy grades for simplified model selection and extended service life
