What is the maximum allowable temperature when drying SFRM for density testing?

The correct answer is 119 degrees F. This temperature is specified to ensure that during the drying process, the structural fire-resistant material (SFRM) maintains its integrity and the moisture content can be adequately evaluated without causing any thermal degradation or other unintended effects on the material's properties.

Keeping the drying temperature below this threshold is crucial for accurately determining the density of the SFRM, as excessive heat can alter its physical characteristics and result in misleading test results. This standard is put in place to ensure consistency in the testing process and to reflect the material's true performance in fire-resistive applications.

Higher temperatures could lead to problems like evaporation of moisture leading to inaccuracies or even damaging the SFRM, which could misrepresent its efficacy and reliability in actual fire scenarios.
