LabTest Certification Expands and Enhances Fire Testing Capabilities
At LabTest Certification, precision and reliability in Fire Testing have always been our top priorities. And now, we’ve taken them even further. We’re excited to announce a series of major upgrades to our Flame Spread Testing Tunnel (Steiner Tunnel), designed to enhance accuracy, efficiency, and turnaround time for your projects.
More samples! | Faster process! | Greater precision!
Our Steiner Tunnel: Fully Refurbished for Peak Accuracy – Completely rebuilt tunnel, with new fire bricks for cleaner, more accurate, and repeatable results.
Over time, the fire bricks that make a Steiner tunnel get aged, burned, cracked, and “soaked” with residues, leading to less efficient equipment. Replacing only the damaged bricks is considered a band-aid approach and can only last for so long. That’s why we’ve completely rebuilt the Steiner Tunnel with new fire bricks, ensuring a cleaner, more stable, and more efficient testing environment. The result? Greater accuracy and repeatability in every test we perform, giving clients even more confidence in their product’s fire performance data.
New Airflow Control System for Smarter Testing – Allows our engineers to fine-tune airflow during tests for better control and data consistency.
We’ve added a new airflow control panel to better manage the tunnel’s behavior before, during, and after testing. Although fully automated, our upgraded system setup also allows our engineers to manually fine-tune airflow in real-time, if and when needed, a flexibility that can make all the difference during critical moments of a test. Think of it like having a skilled driver behind the wheel instead of a driverless car: smarter adjustments, smoother performance, and better overall control.

Software Upgrade: Real-Time Insights and Streamlined Data – Real-time monitoring, automatic plotting, and immediate preliminary results.
Efficiency isn’t only about hardware. Our newly upgraded software now provides:
- Live monitoring of test parameters during each run.
- Automatic data capture and plotting at the push of a button.
- Immediate calculation of Flame Spread & Smoke Developed Index.
This eliminates the need for manual data entry and post-test calculations, significantly reducing reporting time while improving data accuracy.
New Conditioning Room for Larger and Multiple Samples – Accommodates larger and multiple samples under controlled temperature and humidity.
To meet the growing demand for testing larger or multiple materials simultaneously, we’ve added a new conditioning room. This space allows for pre-conditioning a higher volume of samples under controlled temperature and humidity conditions, ensuring each test starts under the most consistent and reproducible circumstances.
If you’re planning upcoming fire tests for building or construction materials, insulation, or any product requiring flame spread or smoke development testing, we’re ready to help!
