If you know your material, product, or building component will be exposed to high temperatures for extended periods of time, why not find out if they can take the heat? Our new International Standards Organization (ISO) 22899-1 compliant testing rig can quantify exactly how long a material can withstand exposure to extreme heat, which allows you to confidently use your heat resistant materials for life’s extreme applications – whether that be for personnel protection, air travel, or even space launch!

ISO 22899-1 Jet Fire Test Rig allows for controlled application of thermal load.

Our new test rig is compliant with the ISO 22899-1 jet fire testing standard, which is located at our Wilfred E. Baker Test Facility (WEBTF) in La Vernia, TX. The purpose of this testing standard is to determine the resistance of passive fire protection materials exposed to jet fires and provides a standardized classification of the material based on its performance. This test is seen as complementary to the ISO/TR 834-3 testing standard. Using this testing apparatus, we can determine how long a particular material can withstand a direct impingement from a jet fire. We hold the flow rate constant and measure the temperature rise in the sample over time. The “time to reach critical temperature rise” is the data point of value we are providing.

How does the Test Rig work?

The testing standard aims to simulate the thermal and mechanical loads imparted to a material by a large-scale hydrocarbon jet fire resulting from a high-pressure flammable release. The fire is applied to a shallow test chamber, which secures the test specimen. Temperature is measured at up to 24 locations on the test specimen, providing an accurate thermal profile over time. BakerRisk has the capability to test to the specified 0.3 kg/s flow rate for up to 1 hour, with expansion capabilities to test for longer periods of time.

The test can be performed in two configurations: an internal configuration where the test specimen is placed inside the box, or an external configuration where the test specimen is installed in front of the box.
The internal configuration is useful for testing the following:

  • Protection systems for plane surfaces
  • Protection systems for edge features
  • Bulkheads and other separating units
  • Penetration systems used in conjunction with bulkheads

The external configuration is useful for testing the following:

  • Protected hollow sections
  • Assemblies mounted on hollow sections

In general, a sample up to the chamber configuration dimensions of 1.620 m × 1.620 m must be provided by the test sponsor. BakerRisk can work with the test sponsor to properly prepare each sample for testing.

Our Testing Services Are a One-Stop-Shop

This new ISO Rig adds to our already impressive testing capabilities, which allow us to test both the thermal and blast

resistance of materials. Combine your ISO 22899-1 certification requirements with the additional blast testing at the WEBTF using our state-of-the-art shock tube, allowing for more comprehensive testing at a competitive cost. Additionally, high‑definition thermal IR video can be recorded throughout the duration of the test – another ability unique to our testing capabilities. We are excited to offer this new testing expertise and we look forward to serving your material testing and classification needs!
