Comply with GB/T5464, ISO1182 "building materials incombustible test methods applicable to the testing of construction materials, the composition of the constituent materials of the products tested, test methods and test results for composite products only used to describe experimentsunder heating conditions of the chamber system made of the flammability of materials or non-flammability. It should not be used to describe or assess fire risk material under actual fire conditions. Testing machine by the furnace, the specimen rack, the air steady flow, air flow hood, circuit control section, the temperature measuring device, and temperature recording, the heating furnace: high 150mm, inner diameter 75mm, outer diameter smaller than 90mm, the electric heating coil monolayer winding heating. Air regulator: the structure of the inverted cone open at both ends, length 500mm, the top of the inner diameter of 75mm uniform reduction in the end the Ministry of 10mm, the airflow cover: high 50mm, the inner diameter of 75mm, the insulation layer is 25mm thick asbestos materials. Fourth, the sample frame: made of heat-resistant steel wire, heat-resistant wire mesh tray mounted on the bottom, 15g five quality temperature measuring device: 1, with Ф1.5mm sheathed thermocouple temperature recorder, multi-channel recording , able to continuously monitor temperature and containing the curve is displayed. Capable of recording the initial temperature of the furnace, the maximum temperature in the furnace, the final temperature of the furnace, the maximum temperature of the center of the specimen, the final temperature of the center of the specimen, the maximum temperature of the surface of the sample, sample surface final temperature. Additional equipment: regulator, regulating transformers, electrical instruments, power controller, timer: 0 ~ 99.99S/M/H can be set
