Introduction
Critical radiation flux is the main parameter for evaluating the fire risk of floor coverings. It represents the burning and spreading ability of floor coverings under the condition of external thermal radiation, and is an important index in the classification system of fire grading of floor coverings.
Working Principle
Flooring Radiant Panel Test Apparatus covering materials is used to measure the critical heat radiation flux of floor covering materials.The critical heat radiation flux is the incident heat per unit area. The greater the incident heat is, the higher the heat required by the material is, the more stable the material is and the less likely it is to catch fire.
