Smoke Toxicity Sampling System (NES 713 / ASTM E662)
With the increasing demand for self-extinguishing and fire-safe building and industrial materials, fire performance is commonly improved by adding flame retardants such as halogen- and phosphorus-based compounds. While these additives reduce flame spread, they often significantly increase the toxicity and opacity of gases released during combustion. In addition, certain flame retardants may generate extremely toxic and hazardous substances such as dioxins and furans during fire exposure.
Therefore, the evaluation of smoke toxicity and hazardous combustion gases generated in public-space fires is of critical importance for life safety assessment.
The Smoke Toxicity Sampling System is developed to meet this demand and is designed specifically for sampling and transfer of combustion gases during smoke toxicity testing.
The system mainly consists of a heated gas transfer line and a test and sampling module, ensuring stable, representative and contamination-free gas sampling for subsequent toxicological analysis.
