The DX8788 Steiner Tunnel is mainly used to test the flame-retardant performance of CMP grade wire and cable, typically used in horizontal subsystems where cables are laid directly in ventilated or forced-ventilation environments without metal conduit. This standard represents the most stringent flame test in the US UL and the entire wire and cable flame-retardant testing field. Only fluoropolymer-sheathed cables can pass this test. Because fluoroplastics have a high decomposition temperature (above 400 C) and a high ignition point (above 800 C), they are not easily ignited when the fire is small, giving them better fire performance than other organic materials.
