The Material Smoke Toxicity Test Apparatus (Mouse Cage Method) is a specialized testing system developed in accordance with GB/T 20285-2006 for evaluating the toxicity hazards of smoke generated by building materials during combustion. The apparatus is primarily used to assess the biological toxicity of smoke under stable smoke-generation conditions and serves as an important basis for determining the combustion performance classification of B- and C-grade composite (sandwich) building materials. By combining controlled thermal decomposition with animal exposure testing, the system provides a scientific and reliable method for fire safety evaluation of construction materials.
Standards
The test apparatus complies with the following national and international standards:
(1) GB/T 20285-2006 – Classification for Toxic Hazard of Smoke Generated by Materials
(2) ISO 19700:2006 – Controlled Equivalence Ratio Method for the Determination of Hazardous Components of Fire Effluents
(3) DIN 53436 – Testing of Thermal Decomposition Products of Materials under Ventilated Conditions and Their Toxicological Evaluation

Features
Designed specifically according to GB/T 20285-2006 for smoke toxicity hazard classification of materials.
Ring furnace adopts an energy-saving full-fiber furnace tube structure with stable thermal performance.
High-precision temperature control system ensures furnace temperature meets the requirements of Chapter 7 of GB/T 20285.
Stepper-motor-driven furnace displacement system provides low noise, high accuracy, and flexible speed selection.
Quartz tube and joints are precision ground and paired during processing to ensure excellent sealing performance.
Waste gases generated during testing are directly discharged into the ventilation duct through plastic hoses, preventing smoke leakage in the working area.
Transparent exposure chamber allows visual observation of test animals during exposure.
Mouse rotating cages are designed to rotate freely, preventing fixed postures and reducing the risk of mechanical injury.
Integrated carrier gas and dilution gas supply system ensures stable smoke concentration control.
Computer-based control system enables high automation and real-time monitoring of test parameters.
