Introduction:

Friction sensitivity testing is one of the most delicate and dangerous aspects of civil explosives safety. The EN 13631-3:2025 standard explicitly requires precise control of friction speed and normal force, and real-time monitoring of thermal effects and reaction signals during the friction process. TESTech's intelligent BAM friction meter, with its superior motion control and multi-sensor fusion technology, has become an industry benchmark under this new standard.

I. Core Parameters: Redefining the Friction Testing Benchmark

Based on the latest product information, new heights have been set in key performance areas:

II. Technological Breakthrough: The Leap from Qualitative to Quantitative

Constant speed and constant force closed-loop control:

In traditional equipment, speed often decreases as resistance increases during friction, leading to lower test results. By employing a servo linear module and force sensor closed-loop feedback, the system can dynamically adjust its output with millisecond-level response, ensuring constant speed and pressure throughout the entire friction stroke. This is a prerequisite for obtaining repeatable and comparable data.

Multimodal ignition identification system:

We have integrated a high-sensitivity acoustic emission sensor (to capture faint crackling sounds), a photodiode (to capture microsecond-level flashes), and a high-frequency force sensor (to capture sudden pressure changes). The system uses a proprietary algorithm to perform logical AND/OR checks on the three signals, significantly reducing false alarm and false alarm rates. Even faint decomposition reactions can be accurately captured and classified.

Real-time analysis of friction coefficient:

The accompanying software can calculate and plot friction coefficient-displacement curves in real time. This is not only used to determine whether an explosion has occurred, but also helps researchers to analyze the tribological properties of materials in depth, providing data support for optimizing insensitive formulations.

III. Why do the world's top laboratories trust TheStyle?

Data consistency verification: In comparative tests with the Shanghai Fire Research Institute of China and a third-party laboratory in Germany, the measured friction sensitivity data (explosion probability/load threshold) deviation was controlled within 5%, proving its excellent international standard.

High-end customization capabilities: Based on our experience in handling complex working conditions accumulated in the C919 large aircraft material testing project, we can provide customized modification solutions according to customers' special needs (such as friction testing in low-temperature/high-temperature environments).

Complete compliance documentation: Complete IQ/OQ/PQ (Installation/Operation/Performance Validation) document templates are provided with the equipment, significantly shortening the laboratory validation cycle.

IV. TESTech's Service Ecosystem

Standard sample package: We provide certified standard calibration samples to help you check the status of your equipment daily.
