Introduction:
Under the new standard EN 13631-4:2025, the traditional "drop hammer test" is now obsolete. The new compliance requirements explicitly stipulate that testing equipment must possess micron-level height control and microsecond-level waveform capture capabilities. Testech's newly launched intelligent BAM drop hammer tester is a precise solution tailored to meet this stringent standard.

Key technical indicators |
Testech performance parameters |
Traditional old equipment |
The new standard (2025) requires |
|
Drop hammer height control |
Servo motor drive + linear encoder feedback ; Accuracy: ±0.1mm ; range: 50mm - 1000mm; steplessly adjustable. |
Manual scale/pneumatic release has large errors and is prone to vibration. |
Forced automation, high-precision control |
|
Data acquisition frequency |
High-speed sampling up to 100 kHz, |
No data acquisition or low-frequency acquisition (<1kHz) |
Complete transient waveform needs to be captured |
|
Explosion detection system |
Tri-modal fusion detection: |
Artificial hearing and sight are highly subjective and have poor consistency. |
Objective automatic judgment |
|
Safety protection |
Fully enclosed explosion-proof chamber + remote control with safety interlock system, stops immediately when the door is opened. |
Open or simple protective measures result in close human-machine contact and high safety risks. |
Forced human-machine separation |
|
Hammer mass |
Standard configuration: 2kg / 5kg / 10kg; optional |
Fixed mass, not calibrated after long-term wear. |
Strict material and weight requirements |
II. In-depth analysis of technical highlights
The Revolution of Servo Drive Systems:
Unlike traditional pneumatic release (which involves air pressure fluctuations) or manual release (which involves human vibration), this system uses an industrial-grade servo motor paired with a high-precision grating ruler. The system can correct the hammer's position in real time, ensuring absolute consistency in impact energy (E=mgh) for each impact. This is crucial for determining the sensitive H50 value (50% probability of explosion height).
Waveform-level data analysis:
The device's built-in high-speed DAQ system can not only tell you "whether it exploded" but also "how it exploded." By replaying the impact waveform, researchers can analyze deeper parameters such as ignition delay time and reaction intensity, providing a scientific basis for formula improvement.
Software architecture compliant with FDA 21 CFR Part 11:
Our control software is designed for highly compliant environments. It features multi-level access control, electronic signatures, and an audit trail. All test data is encrypted and locked once generated to prevent tampering, perfectly meeting the audit requirements of European and American drug and safety regulatory authorities.
III. Global Application Cases and Validation
A leading European chemical company: After introducing the technology, the deviation between its internal laboratory data and that of an external authoritative institution (BAM Federal Institute for Materials Research and Testing) was less than 3%, and it successfully passed the registration of new substances under the REACH regulation.
A national-level civil explosives testing center in China used this equipment to complete the method verification of EN 13631-4:2025, and passed the on-site assessment of the CNAS review group in just two weeks, obtaining the testing qualification for the new standard.
