The GB/T 20285 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.
Application
The apparatus is widely applied in fire safety research, material performance evaluation, and regulatory compliance testing. Typical applications include:
Smoke toxicity assessment of building and construction materials
Combustion toxicity evaluation of composite (sandwich) panels
Fire performance classification testing for interior decoration materials
Safety evaluation of insulation materials and polymer-based products
Toxicological smoke studies in fire research institutes
Type testing and routine inspection in third-party testing laboratories
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
