Flame retardant grade or material or material after processing has obvious delayed properties of flame spread, and divide the hierarchy. Phenolic board of flame retardant grade B1 - then A2 is how to?

test phenolic board flame retardant grade way mainly for phenolic board thickness, burning time, and the distance of the flame. Phenolic plate is divided into 80 cm, 100 cm, 120 cm 3 kinds. In view of the flame on the three thickness of phenolic plate test, each burning respectively for 1 hour, 2 hours, 3 hours. And then testing fire distance resolution for direct combustion, high temperature burning, high temperature combustion for a long time. Get flame retardant grade of the phenolic panel data, the current according to the common data for design of building professional flame retardant grade A1 is the highest, phenolic plate in test scores for high temperature and direct combustion are A2 level, and the long time high temperature burning for B2.
