DX8399 Vertical Combustion Tester for Rigid Foam
【Product Introduction】This machine is suitable for evaluating the
vertical combustion performance of rigid foam or foam rubber under
laboratory conditions;
This machine is suitable for evaluating the horizontal combustion
performance of small specimens of foam with a density of less than
250kg/m3 determined by ISO 845:1985 under small flame under
laboratory conditions.
