Metodos
A Patented 2-Step Process Built for Accuracy, Efficiency, and the Future
Product example
A passive fire protection (PFP) firebox is used to protect an object - for example a flange - from HC pool fire, jet fire and/or high heat flux jet fire according to global ISO standards.
It is crucial that a firebox operates as per design requirements in order to maintain the integrity of the said flange in case of a fire incident. In order to prove this, a firebox has to be exposed to several large-scale fire tests on different weight of flanges for future interpolation purposes.
The ISO setup dictates that the firebox tested should not have an actual flange inside, but the flange should be represented by a "duty object" - a circular object with a wall thickness equal to the weight of a actual flange - in order to allow for interpolation between different sizes/weights of flanges.
The Problem with Traditional Fire Testing on passive fire protection products
Conventional fire testing is:
-
Time-consuming and costly
-
Inflexible, requiring repeated full-scale tests for design modifications in thickness of PFP or the underlying object requiring PFP
-
Environmentally taxing due to energy use and carbon footprint
-
Tests - for fireboxes - are not done on the geometry of the object in need of protection
The traditional approach delays progress, but also increases costs - particularly when approval processes must be restarted due to minor changes or you need to test several iterations of a passive fire protection product.
Most importantly, it is sometimes not done on the geometry of a valve, flange or actuator, but on a "lump of metal" that is supposed to represent said product.
The Metodos 2-Step Solution
Streamline testing with better results and faster results. Below, a full-scale fire test on firebox is used as an example
🔹 Step 1: Execute a large-scale fire test
Produce the firebox as usual. When exposing the firebox to a full-scale fire test, remove the object inside. The full scale fire test should be done on an "empty" box. Record the temperature curve inside the empty firebox which will generate what is referred to as the response curve.
🔹 Step 2: Execute a test in the Metodos container
The computer inside the Metodos container is programmed to replicate the response curve measured inside the empty firebox found in Step 1.
Introduce the actual object that is in need of a firebox in Step 2, and expose it to the response curve. Consequently, the heat sink effect is captured, and we can measure to the minute when Critical Core Temperature (CCT) is reached, or when e.g. an actual flange actually fails
The Benefits of Metodos
✅ Greater Accuracy – A data-informed process improves confidence in results
✅ Faster Turnaround – Streamlined testing enables quicker certification timelines
✅ Cost-Efficiency – Fewer repeated large-scale tests is needed
✅ Sustainability – Reduced carbon footprint and material waste
✅ Reusability – Results contribute to a knowledge platform, enabling long-term reuse of the response curve found in Step 1 through Type Approval Certificates (TACs) issued by classification societies such as DNV
A Platform for Long-Term Value
Unlike one-off fire tests, the Metodos approach transforms findings into reusable knowledge. This means future projects can leverage existing data to gain approvals more efficiently, ensuring consistency and long-term value across your portfolio.
