The smoke toxicity test apparatus (squirrel cage method) is applicable to the GB/T 20285 "Material Smoke Toxicity Hazard Classification" test standard. The test principle is: the uniform quality of the strip sample is subjected to a constant velocity through a ring furnace with stable heating,using constant velocity moving scanning heating, the constant velocity carrier gas flow blows the flue gas in the quartz tube to obtain a stable flue gas flow, which is sent to an independent squirrel cage, and then the state of the experimental white rat is observed and the test result is judged.
