Toxicity Index Tester
Brief Introduction
The ZONSKY Toxicity Index Tester evaluates the safety of wire, cable, and polymer materials by measuring the toxic gases they release when burned. It completely combusts material samples in a controlled chamber, allowing operators to accurately analyze the concentration of harmful gases—such as carbon monoxide and hydrogen cyanide—and calculate a total Toxicity Index.
Description
In compliance with:
- EN 50305:2020 “Railway Facilities. Test Methods for Railway Locomotive Cables with Special Flame Resistant Properties”;
Test process:
- First, a preliminary qualitative analysis is carried out to determine whether it contains nitrogen and sulfur
- If it is determined that nitrogen and sulfur are present, a quantitative analysis of SO2, NOX and HCN should be carried out. If it is confirmed that there is no nitrogen and sulfur, a quantitative analysis of SO2, NOX and HCN can be omitted.
