What condition must TFIFRM meet before it can be subjected to thickness measurements?

Before thickness measurements can be taken for Thermal Fused Intumescent Fire Resistant Materials (TFIFRM), it is essential that the material be stabilized. Stabilization refers to the point at which the material has achieved a certain level of set or structural integrity, allowing it to properly support the weight and function of thickness measuring tools. This ensures that the readings taken are accurate and reflect the true thickness of the fireproofing layer.

If TFIFRM is not stabilized, it may still be in a pliable or unstable state, which could lead to inaccurate measurements or alterations in the thickness due to movement or compression. Therefore, confirming that the material has reached the stabilized condition is crucial for any meaningful assessment of its thickness and, consequently, its performance in providing fire resistance.
