Abstract
The methodological problem of fast and low-cost selection of antiprenes for fire protection of wood-based panels is being solved. Peeled veneer was impregnated with phosphorus-containing compounds based on HEDPA (diacid) and amidophosphate KM (tribasic acid) at a rate less than required for fire protection. Specimens 800 × 56 mm were tested on a semicircle device under conditions of suppressed combustion due to the increasing heat removal as the combustion edge passed along a semicircle with a radius of 254 mm. The parameters of the test results are analyzed to assess the effectiveness of fire retardants. It is concluded that the method is suitable for the initial assessment of fire retardants and selection for the final and certified fire hazard test.
