The toxicity test evaluates the potential impact of smoke and other combustion products on human health. This test is essential for understanding the potential hazards associated with fires and for developing fire safety standards.

Sample Preparation and Burning

To perform the toxicity test as per EN 17084, a sample of the material being tested is burned in a controlled environment, and the effluent produced is collected and analyzed. The test method involves the use of a cone calorimeter, which exposes the sample to a specific heat flux and measures the mass loss rate, heat release rate, and other important parameters.

Toxicity Assessment

The effluent produced during the test is then analyzed for its toxicity using various methods, including Fourier-transform infrared (FTIR) spectroscopy. The FTIR method is used to analyze the chemical composition of the effluent and to identify the presence of toxic gases such as carbon monoxide (CO), hydrogen cyanide (HCN), and other combustion products.

Conventional Index of Toxicity (CITg)

The conventional index of toxicity (CITg) is calculated based on the concentration of toxic gases identified during the FTIR analysis. The CITg is used to determine the potential hazard of the combustion effluent and to compare the toxicity of different materials. A lower CITg value indicates a lower toxicity level of the combustion effluent.
