When can TFIFRM thickness tests be performed?

Thickness tests for TFIFRM (Thermal Fire Insulating Fire-Resistant Material) can be performed after the material has stabilized because this timing ensures that the testing accurately reflects the final cured thickness of the insulation. At this stage, the material has had sufficient time to set and will be less prone to deformation or shrinkage, providing a reliable measurement of the thickness required for effective fireproofing. Properly assessing the thickness after stabilization helps ensure compliance with fire safety regulations and structural integrity requirements.

Testing before installation might not yield accurate results since the material is yet to be applied, while testing during spraying would also present challenges in achieving a precise measurement due to the dynamic nature of the application process. Conducting tests during curing could lead to errors since the material is still transitioning, and properties may vary as it continues to harden. Thus, thickness tests are most valid when the material is fully stabilized and ready for assessment.
