The PDF-60A oxygen index tester is mainly used to evaluate the combustion performance of polymers under specified test conditions, that is, to determine the volume percentage concentration of the lowest oxygen at which the polymer just maintains combustion. The oxygen index tester is suitable for the determination of the combustion performance of polyurethane materials, flame-retardant wood, plastics, rubber, fibers, foam plastics, insulation materials, soft sheets, artificial leather and textiles. It can also be used to determine the performance of building materials B1 and B2.
