In 2026, the field of civil explosives testing will undergo a major transformation unseen in two decades. EN 13631-3/4:2004 will be officially repealed, and the new standard will impose revolutionary requirements on data acquisition frequency, automated control accuracy, and safety interlocks. This article provides an in-depth analysis of the technical logic behind the standard change and reveals how TESTECH, leveraging its verification experience from top global projects such as UL, TUV, and COMAC, can provide you with compliance solutions that meet the highest international standards.
I. The Eye of the Storm: The Leap from "Human Experience" to "Digital Ironclad Evidence"
The older standard (2004 version) relied on operator visual observation and mechanical readings, which inherently suffered from large subjective errors and lack of data traceability. The core change in EN 13631-3:2025 and EN 13631-4:2025 lies in the principle of "data as evidence":
High-frequency sampling mandate: The new standard requires recording the complete impact/friction waveform at a sampling rate of kHz to capture the reaction start point at the millisecond level.
Objectifying the explosion judgment logic: It must be automatically determined through a multi-sensor fusion algorithm of sound, light, and pressure to eliminate human error.
Rigid security isolation: Mandatory separation of humans and machines, with remote control and safety interlock functions.
Current situation warning: According to preliminary research, more than 60% of the equipment in use worldwide are still mechanical or semi-automatic equipment manufactured before 2010. These devices cannot meet the new standards through software upgrades and face the risk of being phased out as a whole.
II. TESTECH: Core Strength Validated by Top Global Projects
Faced with stringent compliance requirements, choosing a supplier is not just about buying equipment, but also about securing a higher success rate. TESTECH is led by a PhD in fire engineering from the US, and its core team members have backgrounds at multinational giants such as Honeywell and 3M. We are not just a manufacturer, but also practitioners of global safety testing standards.
Our Trust Markers:
Preferred by authoritative bodies: We are a globally contracted supplier for UL Solutions (USA), TÜV SÜD (Germany), Intertek (UK), and SGS (France). When these powerful certification bodies use Testech equipment, the credibility of their data speaks for itself.
Verification of Major National Projects:
C919 Large Aircraft Project: We developed the first domestic material combustion testing system that meets FAA/EASA standards for COMAC, helping the domestically produced large aircraft soar into the blue sky.
A benchmark for new energy safety: We provided CATL and BYD with the first battery thermal runaway testing system that meets the UL 9540A standard, setting a new standard for testing in the industry.
R&D Strength: A 4,000㎡ modern base in Suzhou, a high-tech enterprise with over 30 independent intellectual property rights. Every piece of our equipment undergoes a correlation test with European reference laboratories to ensure consistency and reproducibility of results.
III. More Than Just Equipment: Full Lifecycle Compliance Service Package
In response to the revision of EN 13631:2025, Testech launched the "Worry-Free Compliance Program":
Gap Analysis: Free assessment of the gap between your existing equipment and the new standard, with a professional report.
Method Validation Support: Assisting laboratories in completing validation reports for new methods, which is crucial for passing the ISO 17025 expansion review.
Global calibration network: Connects with internationally accredited laboratories such as CNAS and DAkkS, providing traceable calibration certificates.
Expert-level training: Taught by senior engineers involved in the standard research, the training not only teaches operation but also explains the physical mechanisms behind the standard.
Conclusion:
There is no middle ground in compliance. At this crucial juncture of 2026, TESTECH is committed to providing you with the strongest support, leveraging its two decades of technological expertise and global service network. Let the data speak for itself, and let security safeguard your peace of mind.
